GM Enhanced OBD II

The General Motors Enhanced OBD II software upgrade enables access to manufacturer-specific diagnostic trouble codes using your Dyno-Scan for Windows software. Access trouble codes from ABS, BCM, airbag and more. Read and clear B (body) and C (chassis) diagnostic trouble codes from the enhanced systems and turn off the ABS and airbag dashboard light. Thousands of enhanced DTC definitions are included.
