Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Verifying Vehicle Repair
Verification of vehicle repair is more comprehensive for vehicles with OBD-II diagnostic systems. Following a repair, perform following steps:
- Review and record Fail Records and/or Freeze Frame data for stored DTC.
- Clear DTC(s). See CLEARING DIAGNOSTIC TROUBLE CODES .
- Operate vehicle within Fail Records and/or Freeze Frame data.
- Monitor DTC status information for DTC which has been diagnosed, until diagnostic test associated with DTC runs. After diagnostic test runs, and no new fault is recognized, testing is complete.
