Symptom Chart

Condition	Possible Sources	Actions
A module does not respond to the scan tool	Fuse Wiring, terminals or connectors Module	REFER to: COMMUNICATIONS NETWORK .
All illumination (networked and non-networked sources) does not dim or increase brightness	Refer to PINPOINT TEST	GO to PINPOINT TEST G
All networked illumination is inoperative (non-networked illumination functions correctly)	Network communication concern BCM	Using a scan tool, PERFORM a network test. If all modules pass the network test, INSTALL a new BCM . If all modules do not pass the network test, REFER to: COMMUNICATIONS NETWORK .

The LH front window control switch illumination is inoperative or always on (one-touch up and one-touch down window)	Window control switch	VERIFY the operation of the power windows from the LH front window control switch. If the power windows operate correctly from the LH front window control switch, INSTALL a new window control switch. REFER to: FRONT DOOR WINDOW CONTROL SWITCH . If the power windows do not operate correctly from the LH front window control switch, REFER to: GLASS, FRAMES AND MECHANISMS .
The RH front, RH rear or LH rear window control switch illumination is inoperative or always on	Refer to PINPOINT TEST	GO to PINPOINT TEST E
All non-networked illumination is inoperative (networked illumination functions correctly)	Refer to PINPOINT TEST	GO to PINPOINT TEST A
One or more non-networked illumination is inoperative	Refer to PINPOINT TEST	GO to PINPOINT TEST D
A single non-networked illuminated switch or component is always on	Illuminated switch or component	INSTALL a new illuminated switch or component.
The steering wheel switch(es) illumination is inoperative	Refer to PINPOINT TEST	GO to PINPOINT TEST C
All non-networked illumination is always on (networked illumination functions correctly)	Refer to PINPOINT TEST	GO to PINPOINT TEST B
The IPC illumination is inoperative/does not dim	Network communication concern IPC	PERFORM a network test. If the scan tool communicates with the IPC , INSTALL a new IPC . REFER to: INSTRUMENT PANEL CLUSTER (IPC) . If the scan tool does not communicate with the IPC , REFER to: COMMUNICATIONS NETWORK .
The FCIM illumination is inoperative/does not dim (with 8-inch (203 mm) touchscreen only)	FCIM	VERIFY that all FCIM controls function correctly. If all the FCIM controls operate correctly, INSTALL a new FCIM . REFER to: FRONT CONTROLS INTERFACE MODULE (FCIM) . If the FCIM controls do not function correctly, REFER to: INFORMATION AND ENTERTAINMENT SYSTEM .
The CD slot illumination is inoperative (with 8-inch [203 mm] touchscreen only)	Refer to PINPOINT TEST	GO to PINPOINT TEST H
The FDIM illumination is inoperative/does not dim	APIM	VERIFY the audio system can be operated from the FDIM . If the audio system operates correctly from the FDIM inputs, INSTALL a new APIM . REFER to: SYNC MODULE [APIM] . If the audio system does not operate correctly from the FDIM inputs, REFER to: INFORMATION AND ENTERTAINMENT SYSTEM .
The FCDIM illumination is inoperative/does not dim (with 4.2-inch display)	Network communication concern FCDIM	PERFORM a network test. If the scan tool communicates with the FCDIM , INSTALL a new FCDIM . REFER to: FRONT CONTROL/DISPLAY INTERFACE MODULE (FCDIM) . If the scan tool does not communicate with the FCDIM , REFER to: COMMUNICATIONS NETWORK .
The FCIM illumination, including the CD slot illumination, is inoperative/does not dim (with 4.2-inch display)	FCIM	VERIFY that all FCIM controls function correctly. If the FCIM controls function correctly, INSTALL a new FCIM. REFER to: FRONT CONTROLS INTERFACE MODULE (FCIM) . If the FCIM controls do not function correctly, REFER to: INFORMATION AND ENTERTAINMENT SYSTEM .
The HVAC (with Dual Automatic Temperature Control [DATC]) illumination is inoperative/does not dim	Network communication concern HVAC	PERFORM a network test. If the scan tool communicates with the HVAC module, INSTALL a new HVAC module. REFER to: HEATING, VENTILATION AND AIR CONDITIONING (HVAC) CONTROL MODULE . If the scan tool does not communicate with the HVAC module, REFER to: COMMUNICATIONS NETWORK .
