Cargo Door Ajar Indicator Inoperative

Step	Action	Yes	No
Schematic Reference: Body Rear End Schematics
1	Did you perform the Body Rear End Diagnostic System Check?	Go to Step 2	Go to Diagnostic System Check - Body Rear End
2	Open the lift glass or cargo doors. Did the cargo door ajar indicator illuminate?	Go to TESTING FOR INTERMITTENT AND POOR CONNECTIONS	Go to Step 3
3	Connect a scan tool. Turn ON the ignition, with the engine OFF. With a scan tool, command the cargo door ajar indicator ON and OFF. Does the message turn on and off with each command?	Go to Step 4	Go to Step 12
4	Open the cargo door or lift glass. With a scan tool, observe the cargo door or lift glass ajar switch parameter in the BCM data list. Does the scan tool display the switch as active?	Go to Step 9	Go to Step 5
5	Gain access to and disconnect the cargo door or lift glass ajar switch. Connect a 3 amp jumper wire between the signal circuit of the switch and the ground circuit of the switch. With a scan tool, observe the cargo door or lift glass ajar switch parameter in the BCM data list. Does the scan tool display the switch as active?	Go to Step 8	Go to Step 6
6	Test the cargo door or lift glass ajar switch signal circuit for an open, high resistance and a short to voltage. Refer to CIRCUIT TESTING , TESTING FOR CONTINUITY and TESTING FOR A SHORT TO VOLTAGE . Did you find and correct the condition?	Go to Step 13	Go to Step 7
7	Test the cargo door or lift glass ajar switch ground circuit for an open and high resistance. Refer to CIRCUIT TESTING and TESTING FOR CONTINUITY . Did you find and correct the condition?	Go to Step 13	Go to Step 8
8	Inspect for poor connections at the cargo door or lift glass ajar switch(s). Refer to TESTING FOR INTERMITTENT AND POOR CONNECTIONS and CONNECTOR REPAIRS . Did you find and correct the condition?	Go to Step 13	Go to Step 10
9	Inspect for poor connections at the harness connector of the body control module (BCM). Refer to TESTING FOR INTERMITTENT AND POOR CONNECTIONS and CONNECTOR REPAIRS . Did you find and correct the condition?	Go to Step 13	Go to Step 11
10	Replace the door ajar switch. Refer to Latch Replacement - Liftgate or Latch Replacement - Door (Cargo Door Lower) or Latch Replacement - Door (Cargo Door Upper) . Did you complete the replacement?	Go to Step 13	-
11	IMPORTANT: When replacing the BCM refer to BODY CONTROL MODULE (BCM) PROGRAMMING/RPO CONFIGURATION . Replace the body control module (BCM). Refer to BODY CONTROL MODULE REPLACEMENT . Did you complete the replacement?	Go to Step 13	-
12	Replace the instrument panel cluster. Refer to INSTRUMENT PANEL CLUSTER (IPC) REPLACEMENT . Did you complete the replacement?	Go to Step 13	-
13	Operate the system in order to verify the repair. Did you correct the condition?	System OK	Go to Step 3
