Pinpoint Test AE: The Stability-Traction Control Indicator (Sliding Car Icon) Is Never Or Always On

Normal Operation and Fault Conditions
See Stability-Traction Control Indicator (Sliding Car Icon). REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .

If the stability-traction control indicator request message is missing or invalid for less than 5 seconds, the IPC defaults the stability-traction control indicator (sliding car icon) to the last indication mode (on/off) based upon the last message received.

If the stability-traction control indicator request message is missing or invalid for 5 seconds or longer, the IPC defaults the stability-traction control indicator (sliding car icon) on.

AE1 CARRY OUT THE IPC (INSTRUMENT PANEL CLUSTER) INDICATOR LAMP CONTROL ACTIVE COMMAND USING A DIAGNOSTIC SCAN TOOL
- Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).
- Select the IPC stability-traction control indicator (TC/IVD/RSCLMP) PID.
- Command the stability-traction control indicator (sliding car icon) on and off while observing the stability-traction control indicator (sliding car icon).
Does the stability-traction control indicator (sliding car icon) illuminate when commanded on and turn off when commanded off?

Yes GO to AE2

No INSTALL a new IPC. Refer to Instrument Panel Cluster (IPC)

AE2 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Ignition ON.
- Using a diagnostic scan tool, perform the IPC self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?

Yes REFER to DTC Chart: IPC .

No GO to AE3

AE3 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?

Yes REFER to: Communications Network .

No GO to AE4

AE4 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE SELF-TEST

Using a diagnostic scan tool, perform the ABS module self-test.

Are any Diagnostic Trouble Codes (DTCs) recorded?

Yes	REFER to: Anti-Lock Brake System (ABS) and Stability Control .

No	If the stability-traction control indicator (sliding car icon) is never on, the system is operating correctly. If the stability-traction control indicator (sliding car icon) is always on, INSTALL a new IPC. Refer to Instrument Panel Cluster (IPC) .
