- Transmission issues: A scan tool programmer can help you identify and fix transmission problems, which can be expensive and frustrating.
- Airbag errors: The airbag system is critical for safety, and a scan tool can help you pinpoint and address any issues.
- ABS problems: A scan tool can help you diagnose and repair problems with the anti-lock braking system.
