Verifying Vehicle Repair

Verification of vehicle repairs will be more comprehensive for vehicles with the OBD II system diagnostics. Following a repair, the technician should perform the following steps:
1. Review the Failure Records and the Freeze Frame data for the DTC that was diagnosed. Record the Freeze Frame/Failure Records data. The Freeze Frame data will only store for an A or B type diagnostic and only if the MIL has illuminated.
2. Clear the DTCs.
3. Operate the vehicle within the conditions noted in the Freeze Frame/Failure Records data.
4. Monitor the DTC status information for the specific DTC that was diagnosed until the diagnostic test associated with that DTC runs.

Following these steps is very important in verifying repairs on the OBD II system. Failure to follow these steps could result in unnecessary repairs.
