3022628 - I57 INTERIOR LIGHTS NOT WORKING WITH DOORS UNLOCKED BY REMOTE CONTROL

The interior timed lights work if controlled manually and when the doors are opened, but the time period is not activated when the remote control is operated (the door lock/unlock works normally) (If the door lock does not work see Table P10-P11).
When one of the side doors is opened, the courtesy light is turned on for a period of 3 minutes. When the car is unlocked after activation of the remote control, the courtesy light is switched on for a period of 15 seconds, which is interrupted by the ignition ON signal. If the ignition ON signal is present following the opening of a door, the courtesy light comes on.
