Computers and Control Systems: Service and Repair

Following a repair, the technician is to verify that the malfunction is repaired. Verify the repair by performing the following steps:

1. Review and record the Freeze Frame/Failure Records data for the DTC which was diagnosed. The control module will store Freeze Frame/Failure Records data for type A or a type B DTC only, and only then if the MIL has illuminated.

2. Clear the DTCs.

3. Operate the vehicle within the conditions recorded in the Freeze Frame/Failure Records data.

4. Monitor the DTC Status data for the specific DTC which has been diagnosed until the diagnostic test associated with that DTC runs.
