For serious DIY on trucks and SUVs, bidirectional capability lets you command components like the ABS pump or cooling fans directly.

❓ FAQ
What is the best OBD2 scanner for a Chevy or GM?
The Autel MK808 is the best overall for GM DIY, offering bidirectional tests and full-system scans. The Foxwell NT604 Elite is the best value, and BlueDriver is best for phone-based enhanced data.
Do I need enhanced GM coverage?
For engine codes, no. But many GM issues live in ABS, airbag, or body modules, so a tool with enhanced GM coverage diagnoses far more than a generic reader.
Can these tools do ABS bleeds on a GM?
Bidirectional tools like the Autel MK808 and Foxwell NT809 can perform automated ABS bleeds and other active tests on supported GM models. Confirm coverage for your vehicle.
Will a scanner work across Chevy, GMC, Buick, and Cadillac?
Yes. GM shares platforms across its brands, so a tool with GM enhanced coverage generally works across Chevrolet, GMC, Buick, and Cadillac.
Is BlueDriver good for GM trucks?
It is good for reading enhanced codes and generating repair reports, but it is not fully bidirectional. For active tests on trucks, a tool like the MK808 is better.
Do these read transmission codes?
Yes. All the recommended tools read transmission codes, and the more capable ones also read ABS, airbag, and other modules on GM vehicles.
