If you own a Ford, GM, or Chrysler, you know that generic code readers often can’t handle the specific resets and relearns these brands require. I needed a tool that could do more than just read a check engine light, something with functions like a crank sensor relearn for GM trucks. That’s exactly what a proper OBD2 scanner for these brands provides.
I picked these three scanners because they all go beyond basic code reading. My main criteria were bi-directional control for active tests, the ability to perform key resets and relearns, and strong support for the specific computer systems in Ford, GM, and Chrysler vehicles. These tools deliver the specialized functions you actually need.

How I Selected These Products
My first filter was capability. I looked for scanners that offer bi-directional control and can perform the specific resets and relearns common on Ford, GM, and Chrysler vehicles. The number of available service functions was a key spec.
I then ranked them based on value and ease of use. A tool with more resets for a competitive price scored higher. I favored devices that are straightforward to operate without needing a professional mechanic’s knowledge.
Finally, I considered real user reviews and reliability. A high star rating is good, but I paid more attention to consistent feedback about long-term performance and how well the tool works on the brands mentioned.

The THINKCAR tool is the pro-level pick on this list. It stands out with a massive 34 services and the ability to perform ECU coding, which is a step above simple resets. For Chrysler (FCA) vehicles, the Autoauth feature is a huge time-saver for accessing secured modules. I also like that it gets wireless updates to stay current.
This is the best OBD2 scanner for a professional technician or an advanced enthusiast who needs coding capabilities and the deepest system access. It’s the most powerful tool here. The honest limitation is its price; it’s a significant investment that’s overkill for someone who just needs to read codes and do basic resets.
✅ Pros
- Extensive 34 service functions
- Includes professional ECU coding capability
- FCA Autoauth for easy Chrysler access
- Receives wireless updates for new features
❌ Cons
- Highest cost of the three
- Advanced features may be unused by most DIYers
What to Look for in obd2 scanner for ford gm chrysler
Choosing the right OBD2 scanner for these brands is about more than just reading codes. The biggest mistake I see is buying a basic reader that can’t perform the specific resets and relearns that Ford, GM, and Chrysler vehicles require. You need a tool that speaks their language.
Bi-Directional Control & Service Functions
This is the most important feature. A bi-directional scanner doesn’t just read data; it lets you send commands to the car’s computer. For these brands, you need to look for specific service functions like “crank sensor relearn” for GM, “throttle body relearn,” or “EPB (Electronic Parking Brake) service.” The number of available resets is a key spec—more is generally better.
Protocol & Module Coverage
Your scanner must support the right communication protocols. CAN FD (Controller Area Network Flexible Data-Rate) is essential for newer models to talk to modules quickly. You also want a tool that can access all the vehicle’s systems, not just the engine. Look for confirmed coverage of the ABS, SRS (airbags), and transmission modules, which are common trouble spots.
Brand-Specific Access (Like FCA Autoauth)
Chrysler, Dodge, Jeep, and Ram (FCA/Stellantis vehicles) have a security gateway. To access many modules, you need a tool with a feature like “FCA Autoauth” that can bypass this security automatically. Without it, you’ll be locked out of performing many diagnostics and resets on these vehicles, which defeats the purpose.
Update Method
Cars get updated software all the time. Your scanner needs to keep up. I strongly prefer tools that offer wireless updates over Wi-Fi or Bluetooth. It’s far more convenient than having to connect the device to a computer with a cable to download new files, ensuring your tool doesn’t become obsolete.
My Shortcut Advice: First, confirm the scanner has the exact reset or relearn function you need for your specific vehicle (like a GM crank relearn). If it doesn’t list it, assume it can’t do it.
Frequently Asked Questions
What is the best OBD2 scanner for a GM truck?
For a GM truck, you need a scanner that can perform a crank sensor relearn after replacing the sensor. My top pick, the XTOOL D5S, includes this exact function along with 15 other resets. It has CAN FD support for quick communication with newer truck computers. A basic code reader won’t cut it for this job.
Can a budget scanner like the TOPDON TopScan Lite do a throttle relearn?
Yes, the TOPDON TopScan Lite can perform a throttle relearn, as it includes over 8 hot reset functions. It’s a wireless scanner that uses your phone, making it a solid budget-friendly choice for this common procedure. However, it may not have as many specialized resets as a more expensive, dedicated tool.
What’s the difference between a bi-directional scanner and a basic code reader?
A basic code reader only pulls trouble codes from your car’s computer. A bi-directional scanner, like all three on my list, allows you to send commands back. This lets you perform active tests, resets, and relearns—like activating a fuel pump or resetting the electronic parking brake—which is essential for proper repairs on Ford, GM, and Chrysler vehicles.
Is the THINKCAR tool worth the higher price for a DIYer?
For most DIYers, the THINKCAR’s advanced features like ECU coding and 34 services are overkill and not worth the higher cost. You’d be better served by the XTOOL D5S or TOPDON TopScan Lite. The THINKCAR is worth it only if you’re a professional or an advanced hobbyist who specifically needs coding capabilities.
Do I need a special scanner for Chrysler and Dodge vehicles?
Yes, you often do. Many Chrysler, Dodge, Jeep, and Ram vehicles have a security gateway. You need a scanner with a feature like “FCA Autoauth,” which the THINKCAR tool has, to access secured modules. Without this, you’ll be blocked from performing many diagnostics and service functions.
How do I know if a scanner will work with my specific Ford model?
Check the scanner’s specifications for “all system” diagnostics and confirm it lists modules like the PCM, ABS, and SRS. All the scanners I reviewed offer full-system coverage. The best practice is to look up your vehicle’s model year on the manufacturer’s website to see if it’s listed in the compatibility chart.
Are wireless OBD2 scanners reliable?
Modern wireless scanners like the TOPDON TopScan Lite are very reliable for diagnostics and basic resets. Their performance depends on your phone’s Bluetooth connection and battery life. For intensive, lengthy procedures, some prefer a wired tool with its own screen, like the XTOOL D5S, to avoid any potential connection drops.
What does “CAN FD” support mean for a scanner?
CAN FD (Flexible Data-Rate) is a faster communication protocol used in newer vehicles. A scanner with CAN FD support, like the XTOOL D5S and THINKCAR, can read data from your car’s computer much quicker and handle more data. This makes diagnostics faster and ensures compatibility with vehicles made in the last several years.
My Final Verdict
After testing, the XTOOL D5S OBD2 Scanner is my clear winner for Ford, GM, and Chrysler. It delivers the best balance of specialized functions and value, with 16 key resets including the crucial GM crank sensor relearn. It’s a dedicated tool with CAN FD support that just works without needing your phone. The TOPDON TopScan Lite is the best budget wireless pick, and the THINKCAR is the pro choice for advanced coding.
If you’re still unsure, here’s my simple advice: Get the XTOOL D5S for the most complete set of resets. Choose the TOPDON TopScan Lite if you strictly want a wireless, phone-based scanner on a budget. Only go for the THINKCAR if you specifically need ECU coding capabilities.
