Verifying Vehicle Repair

Verifying Vehicle Repair
Verification of vehicle repair will be more comprehensive for vehicles with OBD II system diagnostics. Following a repair, the technician should perform the following steps:
1. Review and record the fail records and/or freeze frame data for the DTC which has been diagnosed (Freeze Frame data will only be stored for an A or B type diagnostic and only if the MIL has been illuminated).
2. Clear DTC(s).
3. Operate the vehicle within conditions noted in the fail records and/or freeze frame data.
4. Monitor the DTC status information for the specific DTC which has been diagnosed until the diagnostic test associated with that DTC runs.

NOTE: Following these steps are very important in verifying repairs on OBD II systems. Failure to follow these steps could result in unnecessary repairs.
