Verifying Vehicle Repair

Verification of the vehicle repair will be more comprehensive for vehicles with on-board diagnostic (EOBD) system diagnostics. Following a repair, the technician should perform these steps:

IMPORTANT: Follow the steps below when you verify repairs on EOBD systems. Failure to follow these steps could result in unnecessary repairs.
• Review and record the Failure Records and the Freeze Frame data for the DTC which has been diagnosed. Freeze Fame data will only be stored for an A or B type diagnostic and only if the MIL has been requested.
• Clear the DTCs.
• Operate the vehicle within conditions noted in the Failure Records and Freeze Frame data.
• Monitor the DTC status information for the specific DTC which has been diagnosed until the diagnostic test associated with that DTC runs.
