Pinpoint Test An: The Stability-Traction Control (Sliding Car Icon) Indicator Or RTT (RECONFIGURABLE Telltale) Indicator Is Never Or Always On
- Normal Operation and Fault Conditions
See Stability-Traction Control (Sliding Car Icon). REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the stability-traction control indicator request is missing or invalid for less than 5 seconds, the IPC defaults the stability-traction control (sliding car icon) indicator or RTT indicator to the last indication state (on or off), based upon the last message received.
If the IPC does not receive the stability-traction control indicator request for 5 seconds or longer, the IPC defaults the stability-traction control (sliding car icon) indicator on.

- AN1 IDENTIFY THE IPC (INSTRUMENT PANEL CLUSTER) LEVEL
- Determine if the vehicle is equipped with a base or mid-level IPC. REFER to: Instrument Panel Cluster (IPC) - Overview
Is the vehicle equipped with a base or mid-level IPC?
Yes GO to AN3 No GO to AN2 - AN2 CHECK THE MESSAGE CENTER OPERATION
- Ignition ON.
- Close all doors, liftgate and hood.
- Clear all message center warnings by pressing the OK button for each warning present.
- Monitor the door ajar RTT warning indicator.
- Open the driver door.
- Clear the message center popup warning.
- Monitor the door ajar RTT warning indicator.
Is the door ajar RTT warning indicator off with the door closed, and on with the door open?
Yes GO to AN4 No GO to Pinpoint Test A - AN3 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) INDICATOR LAMP CONTROL ACTIVE COMMAND
- Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).
- Access the IPC and control the TC/IVD/RSCLMPPID
- Command the stability-traction control indicator (sliding car icon) on and off while observing the indicator.
Does the stability-traction control (sliding car icon) indicator illuminate when commanded on and turn off when commanded off?
Yes GO to AN4 No GO to AN6 - AN4 PERFORM 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 the IPC DTC Chart. No GO to AN5 - AN5 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Communications Network No If the stability-traction control (sliding car icon) indicator is never on, the system is operating correctly. If the stability-traction control (sliding car icon) indicator is always on, DIAGNOSE all ABS module Diagnostic Trouble Codes (DTCs). REFER to:Anti-Lock Brake System (ABS) And Stability Control - AN6 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPC connector.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the IPC connector. Make sure it seats and latches correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
