Terminal And Connection Inspection

1. Disconnect the PCM connectors and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Reconnect the connectors.
2. Connect the GDS and go to "Current Data".
3. Monitor PCM values in Current Data, check and wiggle the harness (es), connector (s), and terminal (s).
4. Any change in the values indicates a poor connection. Was a connector problem found?

YES 

• Repair the connector. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

NO 

• Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
