312000237 - I057 INTERIOR LIGHTS NOT WORKING WITH DOORS UNLOCKED BY REMOTE CONTROL

The timed interior light works if it is switched on manually and when the doors are opened, but the timer is not activated when using the remote control (the doors lock/unlock normally)
When one of the side doors is opened, the timed courtesy light comes on for 3 minutes. When the vehicle is unlocked after operating the remote control, the courtesy light comes on for 15 seconds, which is interrupted by the key on signal. If the key ON signal is present continuously when opening a door, the courtesy lights come on.
