KEY LOCK±IN PREVENTION FUNCTION DOES NOT WORK
PROPERLY (MANUAL OPERATION AND OPERATION
INTERLOCKED WITH KEY ARE ACTIVE)
CIRCUIT DESCRIPTION
The unlock warning switch turns ON when the key is inserted into the ignition key cylinder. The courtesy
lamp switch turns ON when the driver side door is opened. These 2 switches are monitored by the integration
relay. In order to prevent the key from being locked in, the integration relay controls door locking operation
according to the conditions of these switches so that the doors are not locked with the key locked in.
