Interior Lighting Module: Description and Operation

CIRCUIT OPERATION
On vehicles equipped with Remote Keyless Entry (RKE) the Body Control Module (BCM) will turn ON the interior lamps with a valid UNLOCK signal from the RKE transmitter. Circuit M22 is used connected between the RKE module and the BCM. when the signal is received the BCM provides a ground path for circuit M2. This causes the interior lamps to illuminate. The BCM also controls the amount of time ON for the lamps.
