Pinpoint Test I: An Individual Button/Feature Is Inoperative From The Remote Keyless Entry (RKE) Transmitter

Normal Operation

Remote locking and unlocking of the doors and unlocking the cargo doors is accomplished by the Generic Electronic Module (GEM) receiving a command message from the Remote Keyless Entry (RKE) transmitter. The GEM (Generic Electronic Module) processes the command and energizes the appropriate relays to lock or unlock the doors.

The GEM (Generic Electronic Module) will disable the lock and unlock buttons if the ignition key is in any position other than OFF or LOCK. The rear cargo door unlock button works in any ignition position.

This pinpoint test is intended to diagnose the following:

- Cargo door lock

- Door locks
