I/P Courtesy Lamps Inop

Possible Causes are:

• BCM I/P COURTESY LAMPS INOP
• BULBS OPEN
• OPEN FUSED B (+)
• COURTESY LAMP CONTROL CIRCUIT OPEN

1. Remove and check inoperative bulbs. Are the bulbs OK? If yes, go to next step. If no, replace the bulbs. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
2. Measure the voltage of the Fused B (+) circuit to the Lamp. Is the voltage more than 10 volts? If yes, go to next step. If no, repair the open Fused B (+) circuit back to splice. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
3. Turn ignition off. Disconnect the BCM C1 connector. Gain access to an inoperative bulb. Measure the Courtesy Lamp Control circuit from the BCM C1 connector to the bulb connector. Is the resistance less than 5 ohms? If yes, replace the Body Control Module. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, repair the open Courtesy Lamp Control circuit. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS.
