Is the concern still present?

Ignition OFF. Disconnect and inspect the APIM connector. Repair:

Corrosion (clean module pins or install new connectors or terminals) Damaged or bent pins (install new terminals or pins) Pushed-out pins (install new pins as necessary)

Reconnect the APIM connector. Make sure it seats and latches correctly. Operate the system and determine if the concern is still present.
