Description And Operation
DESCRIPTION
The Integrated Center Stack (ICS) Module (1) is located on the lower center stack.
OPERATION
This ICS module is available in multiple configurations, which vary depending upon the equipment in the vehicle. The ICS module allows manual control of the multiple vehicle systems. The ICS module communicates on the Controller Area Network - Interior High Speed (CAN-IHS) data bus and controls all connected vehicle systems via CAN messages.
The switch housing and the push buttons are constructed of molded plastic. Each push button has a smooth finish and is clearly identified with the appropriate text and International Control and Display Symbol icons. Several of the push buttons feature Light Emitting Diode (LED) units to give the vehicle operator an indication when the function of that switch is currently active. The back of the switch housing has an integral connector receptacle containing terminal pins that connect the switch to the vehicle electrical system through a dedicated take out and connector of the instrument panel wire harness. Panel lamps dimmer controlled illumination lamps integral to the circuit board within the switch provide back lighting for visibility at night.
The ICS module is the user interface for many functions and features in the vehicle.
The following features can be accessed through the ICS module as equipped:
- All radio functions
- Lane Departure Warning (LDW)
- Parking Assist System (PAS)
- Climate Control System
- Front and Rear defroster
- Passenger airbag ON/OFF
- Audio MUTE
- Radio SCREEN OFF
- Hazard Switch
For additional information regarding each system the ICS module controls, refer to the information related to the feature.
The ICS module receives fused B+ from a fuse in the Power Distribution Center (PDC) and ground through a connection at a ground stud behind the right kick panel.
The individual controls located in the ICS module cannot be adjusted or repaired. If any control on the ICS module or control indicator lamp is inoperative or damaged, the entire ICS module must be replaced. Refer to MODULE, INTEGRATED CENTER STACK (ICSM), REMOVAL AND INSTALLATION .
The individual controls located in the radio touch screen cannot be adjusted or repaired. If a radio touch screen control or control indicator lamp is inoperative or damaged, the entire radio must be replaced. Refer to MODULE, RADIO RECEIVER, REMOVAL AND INSTALLATION .
Prior to replacing an ICS module, check for any Diagnostic Trouble Codes (DTCs) related to the affected system, and run any related calibration procedures to verify that the concern is not a calibration issue. Refer to STANDARD PROCEDURE .
