Key Confinement Prevention Function Does Not Work Properly (Unlock Warning Switch Circuit)

KEY CONFINEMENT PREVENTION FUNCTION DOES NOT WORK PROPERLY (UNLOCK WARNING SWITCH CIRCUIT)

CIRCUIT DESCRIPTION

The unlock warning switch turns on when the key is inserted in the ignition key cylinder, and the door courtesy switch turns on when the driver's door is opened. The integration relay monitors both of these switches. The integration relay controls the door locking operation so that doors do not lock while both switches are on in order to prevent the key from being locked in the vehicle.
