- Verdict: which OBD2 scanner fits your Ram 1500?
The best OBD2 scanner for Dodge Ram 1500 owners is the MOTOPOWER MP69033, because it reads and clears check engine codes on any 1996+ OBD II truck and shows the fault definition on its own screen. If your Ram is a 2018 or newer FCA truck and you need ABS or airbag codes, the BlueDriver is the smarter buy.
Ram 1500s are simple to scan at the engine level. Every US-market truck since 1996 speaks standard OBD II, so a basic reader tells you why the check engine light is on and lets you clear it after a fix.
The tricky part is the newer trucks. FCA added a Security Gateway on many 2018+ models, and that gate can block code clearing unless the tool supports it.
Autel warns that its MS309 cannot clear codes on FCA vehicles built after 2017.
So the real question is what you want to scan. For engine and emissions codes only, a handheld reader is the cheapest way in.
For ABS, airbag and tire pressure codes on a newer truck, an app-based scanner with Stellantis coverage is the safer bet. If you own other VW or Audi vehicles in the household, our roundup of the best OBD2 scanner for VW covers the same choice for those brands.

Best OBD2 scanners for Dodge Ram 1500 by job
Every scanner here reads engine codes on a Ram 1500. They split on price, screen, live data and how deep into the truck's systems they reach.
Pick by the job you need done, not by the longest feature list.
MOTOPOWER MP69033 Car OBD2 Scanner Code Reader: Best for basic check engine light scans
- Built-in OBD2 DTC lookup library
- 2.8 in LCD screen with contrast adjustment
- Reads and clears check engine codes
- 9 OBD II protocols, 6 languages
A cheap, simple code reader that handles the check engine light jobs most Ram owners actually need. The built-in lookup library means no phone and no app.
Pros
- Built-in DTC definitions on screen
- No battery or charger needed
- 6 languages
Cons
- No ABS or airbag codes
- No Bluetooth or app
MOTOPOWER's MP69033 is the pick for the driver who sees a check engine light and wants an answer without a phone or an app. It's a classic handheld reader: plug it into the 16-pin port, turn the key, press OK, and the fault code shows on the 2.8 in LCD with its definition from the built-in library.
That built-in lookup matters more than the screen size on a Ram. You get the code and the meaning in one place, so you don't have to search the web in a parking lot.
It also reads freeze frame data, readiness monitors and vehicle info, and shows live data as numbers and a real-time curve once the engine is running.
The trade-offs are clear. It covers engine and emissions codes only, so the ABS light or an airbag warning stays invisible to it.
There's also no Bluetooth, so nothing logs to your phone. For basic Ram diagnostics, that's fine.
It's the strongest value in this group because it does the common job well without extra hardware.
Autel OBD2 Scanner MS309 Universal Car Engine: Best for smog check prep
- Reads generic and manufacturer-specific codes
- Freeze frame and VIN readout
- I/M readiness status
- 12-month warranty
Shows the fault code definition right on the screen and tracks readiness monitors, so you know whether the truck will pass an emissions test.
Pros
- DTC definitions on screen
- Freeze frame and vehicle info
- Built-in database of 1000+ codes
Cons
- Does not clear codes on post-2017 FCA vehicles with the security gateway
- No ABS or service functions
The Autel MS309 is the reader to pick if a smog or emissions test is coming up. Its I/M readiness screen shows whether the truck's monitors have finished their self-tests, so you know before you drive to the test center whether you'll pass.
It also reads and clears generic, manufacturer-specific and pending codes, and it displays the definition under each code from a database of more than 1000. Freeze frame and VIN readout help when you're checking whether a used truck's computer matches its paperwork.
The screen is small at 1 in, so this is not the tool for watching live data while you drive. And the FCA security gateway is the real limit: Autel states the MS309 cannot clear codes on Chrysler, Dodge and Jeep vehicles made after 2017.
On an older Ram 1500 it's an excellent buy. On a newer one, treat it as a reader that may be blocked from clearing.
OBDLink MX+ Bluetooth Scanner: Best for app-based diagnostics on a phone
- Bluetooth for iPhone, Android and Windows
- Enhanced OEM support for Ford, GM, Mazda and more
- Over-voltage and battery drain protection
- Free lifetime firmware updates
A pocket adapter that turns your phone into a scan tool. The included app graphs and logs live engine data, and the unit stays out of the way in the footwell.
Pros
- Works with iPhone, Android and Windows
- Graphs and logs live data
- Sleep mode prevents battery drain
Cons
- Needs a phone or PC to see anything
- Enhanced OEM support covers Ford, GM, Mazda and others, not Stellantis
The OBDLink MX+ is the adapter for someone who wants a real scan tool on their phone. It's a small Bluetooth plug that pairs with iPhone, Android or Windows, and the free OBDLink app graphs, logs and exports live engine data.
You can watch fuel trims and coolant temperature on the road and save a log to share with a mechanic.
It's built to stay plugged in. The over-voltage and battery drain protection plus intelligent sleep mode mean it won't kill the truck's battery between drives.
The maker also provides free lifetime firmware updates, so the adapter doesn't go stale.
The honest catch for Ram owners is coverage. OBDLink lists enhanced OEM support for Ford, GM, Mazda, Nissan and Toyota, not for Stellantis.
So on a newer Ram, expect standard engine and emissions codes rather than ABS or airbag access. For live engine data and long-term logging on a phone, it's the best in this group.
Our roundup of the best OBD2 scanners for iPhone covers the app side in more detail.
VDIAGTOOL VD10 OBD2 Scanner Check Engine Code: Best for a dedicated truck-glovebox reader
- 2.1 in LCD with backlight
- Built-in database of 3000+ codes
- Live data and freeze frame
- I/M readiness for emissions checks
A standalone reader with a screen you can read in daylight. It covers the engine and emissions checks a Ram owner needs without tying up a phone.
Pros
- Built-in code definitions
- Live data and freeze frame
- 6 languages
Cons
- No ABS or airbag codes
- No Bluetooth or app
The VDIAGTOOL VD10 is the truck-glovebox reader. It's a standalone handheld with a 2.1 in backlit LCD and a built-in database of more than 3000 codes, so it shows the fault definition on screen without a phone.
The screen is small, but the backlight makes it readable in a dim garage.
It reads and clears codes, shows live data such as RPM and fuel trim, captures freeze frame, and checks I/M readiness. For a Ram owner who mostly deals with an engine light after a rough week of towing or hauling, that covers the essentials.
VDIAGTOOL also says it supports all five OBD II protocols, so a 1996+ Ram is in scope. The limits are the same as the cheaper readers: engine and emissions only, no ABS, airbag or transmission codes.
Pick it if you want a dedicated tool with a screen that never depends on your phone's battery.
BlueDriver Bluetooth OBD2 Scanner: Best for Stellantis-era Ram 1500s
- Bluetooth adapter for iOS and Android
- Reads ABS, SRS, TPMS and transmission codes on supported vehicles
- Technician-verified repair reports by VIN
- No subscription fees
BlueDriver lists Stellantis (RAM, Jeep, Chrysler) among its strong coverage, so it is the app scanner to look at first for a newer Ram. It reads more than engine codes.
Pros
- ABS, SRS and TPMS codes on supported trucks
- Repair reports matched to your VIN
- One-time price, no subscription
Cons
- Needs a phone
- Enhanced coverage varies by model year
BlueDriver is the app scanner to look at first for a newer Ram 1500. It lists Stellantis (RAM, Jeep, Chrysler) among its strongest coverage, and it reads and clears ABS, SRS, airbag and TPMS codes on supported vehicles.
That matters when the ABS light comes on after a winter of salted roads or the tire pressure warning won't clear.
It also gives repair reports matched to your VIN, with definitions and confirmed fixes. You monitor live data, view freeze frames and check smog readiness from the app.
There's no subscription, so one purchase covers all the features.
The trade-off is that everything runs through your phone, and enhanced coverage varies by model year. It costs more than a basic reader, but for a 2018+ truck with more than engine codes, it's the pick.
Owners with a fleet of vehicles will also get value from the multi-system scans.
Foxwell NT301 Code Reader: Best for live data graphing on a budget
- 2.8 in color screen
- Live sensor data in graphs
- One-click I/M readiness with red-yellow-green LEDs
- EVAP and O2 sensor tests
Graphs live sensor data such as oxygen sensors and fuel trims without a phone. The three-color readiness indicator makes emissions prep simple.
Pros
- Graphs live engine data
- EVAP and O2 sensor tests
- Lifetime free updates
Cons
- No ABS or service functions
- Updates need a Windows PC
The Foxwell NT301 is the best cheap way to get live data graphs. Its 2.8 in color screen plots oxygen sensors, fuel trims, coolant temperature and RPM, so you can spot a lean condition or a lazy sensor without a phone or app.
The readiness check is easy to read: three LEDs show red, yellow or green for your emissions status. The NT301 also runs EVAP and O2 sensor tests, which is more than the basic readers here offer.
For a Ram that has to pass an annual test, that's practical.
It only covers engine and emissions codes. There are no ABS, airbag or service functions, and updates require a Windows PC.
If you want the deepest engine-side diagnosis at a low price, this is the one. If you need ABS coverage, step up to BlueDriver instead.
ANCEL AD310 Code Reader: Best for first-time DIY owners
- 2.4 in screen with clear results
- Reads and clears emission-related codes
- Freeze frame and live data
- 2.5 ft cable with thick insulation
A sturdy, easy-to-hold reader for someone who just wants to know why the check engine light is on. No phone, no app, no setup.
Pros
- Simple for beginners
- Rugged cable and case
- Reads live data and freeze frame
Cons
- Engine and emissions codes only
- No ABS or reset functions
The ANCEL AD310 is the reader for a first-time DIY owner. It's built to be dropped: a 2.5 ft cable with thick, flexible insulation, a rugged case and clearly labelled buttons.
Plug it in, turn the key and read the code.
It reads and clears emission-related engine codes and shows live data and freeze frame, and it supports all five OBD II protocols. The 2.4 in screen displays results clearly, and there's no battery or charger to manage.
The honest limit is depth. It handles engine and emissions codes only, and it can't read an engine fault that isn't emission-related.
There are no reset or service functions either. For someone who just wants to know why the check engine light is on and clear it after a repair, it's simple and sturdy.
For anything beyond that, look higher up this list.
ANCEL AD410 Code Reader: Best for used Ram shopping checks
- 42,000+ built-in DTC lookups
- 2.4 in color screen
- Live data with graphs
- Freeze frame and VIN readout
A color-screen reader with a big code library and live data graphs. Handy when you are checking a used truck's history before you buy.
Pros
- Large built-in code library
- Live data graphs
- No app needed
Cons
- Engine and emissions codes only
- No ABS or service resets
The ANCEL AD410 suits someone checking a used Ram 1500 before buying. Its built-in database covers more than 42,000 code lookups, so the definition is on screen for almost any code the truck throws.
The 2.4 in color screen shows live data graphs for RPM, coolant temperature, fuel trim and oxygen sensors. You can verify a repair after fixing a problem and confirm the readiness monitors before a smog check.
The 16-pin plug needs no battery, Bluetooth or app.
Like the other ANCEL models, it reads engine and emissions codes only. It does not support ABS, SRS or transmission codes.
If you're buying a used truck and want to know whether the engine light is a real problem or a loose gas cap, the AD410 gives you a fast answer without a phone.
Autel AutoLink AL319: Best for a spare reader in the toolbox
- 2.4 in color TFT display
- One-click I/M readiness
- Built-in speaker and LED indicator
- Reads and clears engine codes
A small color-screen reader for occasional use. It covers the basic engine and emissions checks and fits easily in a toolbox.
Pros
- Small and easy to store
- One-click readiness check
- 7 languages
Cons
- Lowest score in this group
- No ABS or airbag codes
The Autel AutoLink AL319 is a small, spare reader to keep in the toolbox. It's compact, has a 2.4 in color TFT display and covers the basic engine and emissions checks, including a one-click I/M readiness check and a built-in speaker for audio feedback.
It reads and clears engine codes and shows the definition on screen. The cable is long enough without getting in the way.
It's the lowest-scored tool here because it offers less depth than the others, and like them it can't read ABS or airbag codes.
Choose it as a backup or for a second vehicle that only needs occasional engine scans. If this is your only scanner for a Ram 1500, spend a little more on the MOTOPOWER or the VDIAGTOOL for a bigger screen and more code coverage.
How these OBD2 scanners for Dodge Ram 1500 were compared
We compared these scanners by what a Ram 1500 owner needs in daily use: reading and clearing engine codes, checking emissions readiness, and reaching systems beyond the engine on newer trucks. We checked each tool's stated protocol support, its screen, its live data features, its code database and its FCA security gateway limits.
We also weighed whether each tool needs a phone and how it handles a plugged-in life in the truck. Our score weighs specs, features and buyer feedback against what you're shopping for.
The top picks earn their place on the everyday jobs, and the lower scores reflect narrower coverage or fewer features, not a bad tool for the right buyer.

Does a Dodge Ram 1500 use standard OBD2?
Yes. A Ram 1500 sold in the US from 1996 onward uses standard OBD II with the 16-pin connector under the dash, so any scanner in this roundup can read engine and emissions codes.
The protocol support covers CAN, ISO9141, KWP2000 and both J1850 variants, which is what the MOTOPOWER, VDIAGTOOL and ANCEL readers list.
The catch is the newer trucks. FCA added a Security Gateway on many 2018+ models, and that gateway can block a tool from clearing codes unless it supports the system.
So "works on a Ram" depends on the model year as much as the connector.
What changes on 2018 and newer Rams?
The Security Gateway sits between the OBDII port and the truck's modules. Autel states its MS309 cannot clear codes on Chrysler, Dodge and Jeep vehicles made after 2017.
BlueDriver lists Stellantis coverage and reads ABS and airbag codes on supported trucks, which makes it the safer pick for a newer Ram. Check the tool's gateway support before you buy if your truck is 2018 or newer.
Will an older Ram 1500 work with any of these?
Yes. A 1996 to 2017 Ram 1500 has no security gateway barrier for basic engine codes, so even the cheapest reader here works.
The MOTOPOWER MP69033, VDIAGTOOL VD10 and ANCEL AD310 all handle engine codes and readiness checks on those trucks. Pick by screen size and live data needs rather than by gateway support.
Do you need ABS and airbag codes on a Ram 1500?
Only if those warning lights are on. Basic readers like the MOTOPOWER and the ANCEL models read engine and emissions codes only, so an ABS, airbag or tire pressure light stays invisible to them.
BlueDriver reads ABS, SRS and TPMS codes on supported vehicles and lists Stellantis among its strong coverage. If your Ram shows more than a check engine light, that's the tool to buy.
What does BlueDriver add for a Ram owner?
It reads and clears codes for the engine plus ABS, SRS, airbag, TPMS and transmission on supported vehicles. It also gives technician-verified repair reports matched to your VIN, so you see likely causes and confirmed fixes.
For a newer truck with multiple systems, that's a real step up from an engine-only reader. The catch is that enhanced coverage varies by model year.
When is an engine-only reader enough?
For most Ram owners, most of the time. The check engine light is the warning that shows up first, and a reader like the MOTOPOWER or the Foxwell NT301 tells you why and lets you clear it after a fix.
If you only ever see the engine light, an engine-only reader saves money. Save the multi-system scanner for the day another light appears.
Which OBD2 scanner shows live engine data on a Ram?
The Foxwell NT301 and the OBDLink MX+ are the best live data choices here. The NT301 graphs sensor data on its own color screen, while the MX+ logs to your phone with the free OBDLink app.
The MOTOPOWER MP69033 and VDIAGTOOL VD10 also show live data, but as numbers and simple curves rather than full graphs. Pick the NT301 for a screen and the MX+ for logging and sharing.
Our roundup of the best OBD2 scanners with live data compares the app and screen options in more depth.
Is a phone app better than a handheld for live data?
A phone app gives you bigger graphs, logs you can save and share, and free updates. The OBDLink MX+ is built for that, and its app graphs and exports real-time engine data.
A handheld is simpler: no pairing, no phone battery to manage. The Foxwell NT301 gives you graphs on its own screen.
For a Ram owner who wants to study fuel trims over a long tow, the app route is better.
What can live data tell you about a Ram?
Live data shows what the engine is doing in real time: RPM, coolant temperature, fuel trims, oxygen sensor readings and misfire counts. A lean fuel trim or a lazy oxygen sensor shows up as a pattern, not a single code.
That helps you decide whether a fault is a sensor, a vacuum leak or something worse before you pay a shop.
How much should you spend on a Ram 1500 scanner?
Start with the job. A basic engine-only reader covers the check engine light for most owners.
An app scanner with ABS and airbag coverage costs more but reaches the systems that matter on a newer truck. The MOTOPOWER MP69033 sits at the budget end and covers the common jobs.
BlueDriver sits at the top of this group for multi-system coverage. The Innova 5210 is another option if you want to compare a mid-range handheld against these; our Innova 5210 review covers what it does.
Is a cheap reader good enough for a Ram?
For engine codes, yes. The MOTOPOWER MP69033 reads and clears check engine codes on any 1996+ Ram and shows the definition on screen.
What you give up is ABS and airbag access and app logging. If the check engine light is your only concern, a cheap reader is the right buy.
If you plan to keep the truck for years and want full diagnostics, spend more once.
What do you get by spending more?
More systems. BlueDriver reads ABS, SRS, TPMS and transmission codes on supported trucks and gives repair reports by VIN.
The OBDLink MX+ gives you phone-based live data logging with enhanced support on some brands. Neither is required for a basic engine light.
They pay off when a warning light other than the engine light shows up or when you want to study live data.
What should you check before buying an OBD2 scanner for a Dodge Ram 1500?
Check three things: your model year against the FCA security gateway, whether you need ABS and airbag codes, and whether you want a screen or a phone app. A 2018+ Ram needs a tool with gateway support for code clearing.
An engine-only reader is enough if the check engine light is your only concern. A screen reader suits a glovebox; an app scanner suits live data logging.
Does the scanner need a subscription?
No. Every tool in this roundup works without a subscription.
BlueDriver charges once and includes all its features with no add-ons. The OBDLink MX+ app and firmware updates are free.
The Autel MS309 and Foxwell NT301 offer free updates as well. Avoid any scanner that pushes a monthly fee for basic code reading.
Can a scanner stay plugged into the Ram?
Yes. The OBDLink MX+ and BlueDriver both draw power from the OBDII port and include protection against battery drain.
Leave the adapter in place and pair your phone when you need a scan. Handheld readers like the MOTOPOWER are meant to be plugged in for a scan and then unplugged.
Either way, a plugged-in adapter is not a problem on a Ram 1500.
Verdict: which OBD2 scanner fits your Ram 1500?
For most Dodge Ram 1500 owners, the MOTOPOWER MP69033 is the best OBD2 scanner to buy. It reads and clears engine codes on any 1996+ truck, shows the definition on a 2.8 in screen, and needs no phone or app.
Pick the BlueDriver if you have a 2018 or newer Ram and want ABS and airbag codes too. Pick the Foxwell NT301 if live data graphs on a budget matter more than ABS coverage.
For a dedicated glovebox reader that never depends on your phone, the VDIAGTOOL VD10 is the value pick. Whichever you choose, confirm the security gateway support on a newer truck before you order.

Frequently asked questions
Will a generic OBD2 scanner work on a Dodge Ram 1500?
Yes. A Ram 1500 sold in the US from 1996 onward uses standard OBD II, so any scanner here can read engine and emissions codes.
The limit is the security gateway on newer FCA trucks, which can block code clearing unless the tool supports it.
Why won't my scanner clear codes on a newer Ram?
FCA added a Security Gateway (SGW) on many newer vehicles, including Ram. It blocks access to OBDII modules for tools without SGW support.
Autel says its MS309 cannot clear codes on FCA vehicles made after 2017.
Check that your scanner supports the gateway before you buy.
What does I/M readiness mean for a Ram emissions test?
I/M readiness shows whether the truck's emissions monitors have finished their self-tests since the last code clear. If monitors are not ready, the truck can fail a smog or inspection test.
Readers like the Autel MS309 and VDIAGTOOL VD10 show this status.
