Illuminated Entry

The interior lamp control module supplies a ground path for the interior courtesy lighting. When the interior lamp control module receives a signal from any of the door jamb switches in the vehicle indicating that a door has been opened. This signal will come from CKT 157 (TAN) off of one of the door jamb switches. When the interior lamp control module receives a signal form the door jamb switches, the module provides a ground path for CKT 156 (WHT), which in turn lights all of the interior courtesy lighting. Lighting will remain on for 20 seconds or until the ignition switch is in the on position, whichever occurs first.
