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 the fail records and the Freeze Frame data for the DTC which was diagnosed. The Freeze Frame data will only store for an A or B type diagnostic and only if the MOIL has illuminated.
2. Clear the DTCs.
3. Operate the vehicle within the conditions noted in the fail records or the Freeze Frame data.
4. Monitor the DTC status information for the specific DTC which has been diagnosed until the diagnostic test associated with the DTC runs.
Following these steps are very important in verifying repairs on the OBD II system. Failure to follow these steps could result in an unnecessary repair.
