Verifying Vehicle Repair

Verification of the 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 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 requested.
2. Clear the DTCs.
3. Operate the vehicle within conditions that are noted in the 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.

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