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 into the ignition key cylinder and the door courtesy switch turns on when the driver side door is opened. The integration relay monitors the condition of both switches. If the integration relay detects that both the unlock warning switch and door courtesy switch are on, the integration relay prevents door lock operations so that the key cannot be locked in the vehicle.
