DEFINITION: The interior courtesy lights do not activate when a door is open.

Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

1. Place the ignition in the RUN position.
2. Turn the dimmer switch to the DOME position.

Do the courtesy lights illuminate?

Go to Step 3

Go to Courtesy Lamps Inoperative

1. Turn the interior lamps override switch to the ON position.
2. Close all doors and the liftgate.
3. Open and close all doors and liftgate one at a time using the following procedure:

3.1.	Open one of the doors or liftgate.

3.2.	Close the door or liftgate and wait for the courtesy lamps to turn OFF.

Do the courtesy lights illuminate when each door or liftgate is opened?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 4

Important: The body control module (BCM) has 4 separate modes that can disable or enable the illuminated entry lamps. Determine the interior illumination mode before preceding. Refer to Vehicle Personalization in Personalization.

Is the BCM in the appropriate personalization mode for illuminated entry operation?

Go to Step 5

Go to Vehicle Personalization in Personalization

1. Disconnect the door lock or door jamb switch of the inoperative door or liftgate.
2. Connect a fused jumper between the switch signal circuit of the door lock or door jamb switch connector and ground. Refer to Circuit Testing in Wiring Systems.

Do the courtesy lamps illuminate?

Go to Step 6

Go to Step 7

Connect a fused jumper between the switch signal circuit and the ground circuit of the door lock or door jamb switch connector. Refer to Circuit Testing in Wiring Systems.

Do the courtesy lamps illuminate?

Go to Step 8

Go to Step 10

Test for an open, high resistance, or short to battery positive voltage in the switch signal circuit of the inoperative door lock or door jamb switch. Refer to Circuit Testing or Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 13

Go to Step 9

Inspect for poor connections at the harness connector of the inoperative door lock switch or door jamb switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 13

Go to Step 11

Inspect for poor connections at the harness connector of the BCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 13
