Pinpoint Test E: The Traction Control System Is Inoperative Or Cannot Be Disabled Using The Message Center
- NOTE: If equipped, MyKey allows users to configure traction control to be either always on or selectable. If a MyKey restricted key is in use with the MyKey traction control feature configured to always on, traction control cannot be disabled. An admin key must be used to enable and disable traction control.NOTE: This test requires the use of at least 2 ignition keys (passive or IKT) programmed to the vehicle; one admin ignition key and one restricted ignition key.
Normal Operation and Fault Conditions
The stability-traction control disabled indicator (sliding car OFF icon) in the IPC provides traction control system status to the driver. When the driver deactivates the traction control, the IPC sends a message to the GWM over the HS-CAN3 indicating the driver has requested the traction control to be disabled. The GWM relays this message to the ABS module over the FD-CAN. The ABS module continues to monitor for excessive wheel spin, but no longer takes any action when a traction event is detected. The traction control system remains deactivated until the driver changes the traction control state in the message center or until the ignition is cycled.
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition ABS C1109:24 Vehicle Dynamics Control Switch: Signal Stuck High Sets when the message from the IPC indicates the traction control switch message is sent for too long. This is likely due to an internal failure of the IPC. Possible Causes
- A MyKey restricted key is in use
- Network communication concern
- GWM concern
- Message center concern
- IPC concern
- E1 VERIFY THE IGNITION KEY IN USE IS NOT RESTRICTED
- Ignition ON.
- Monitor the message center.
Does the message center display MYKEY ACTIVE DRIVE SAFELY?
Yes The current ignition key is a restricted key and is operating correctly. REPEAT the test step using a different ignition key until the message center does not display MYKEY ACTIVE DRIVE SAFELY. GO to E2 No GO to E2 - E2 VERIFY THE MYKEY® TRACTION CONTROL SETTING
- Using the message center, verify the MyKey traction control setting.
- Refer to the Owner's Literature for instructions on setting the MyKey functions.
Is the MyKey traction control setting configured to always on?
Yes GO to E3 No GO to E4 - E3 VERIFY TRACTION CONTROL FUNCTION CAN BE DISABLED USING THE ADMIN IGNITION KEY
- Using the message center, verify traction control can be enabled and disabled using the admin ignition key.
- Refer to the Owner's Literature for instructions on enabling and disabling traction control.
Can traction control be enabled and disabled using the admin ignition key?
Yes The system is operating correctly at this time. The concern may have been caused by the use of a restricted key. INFORM the customer the traction control can only be disabled using an admin key when the MyKey® traction control setting is configured to always on. No GO to E4 - E4 CHECK FOR ABS (ANTI-LOCK BRAKE SYSTEM) MODULE DTC (DIAGNOSTIC TROUBLE CODE) S
- Ignition OFF.
- Ignition ON.
- Using a diagnostic scan tool, carry out the ABS module self-test.
Are any DTC s present?
Yes REFER to the ABS Module Diagnostic Trouble Code (DTC) Chart . No GO to E5 - E5 CHECK FOR GWM (GATEWAY MODULE A) DTC (DIAGNOSTIC TROUBLE CODE) S
- Ignition OFF.
- Ignition ON.
- Using a diagnostic scan tool, carry out the GWM self-test.
Are any DTC s present?
Yes DIAGNOSE any GWM DTCs. REFER to: Controller Area Network (CAN) Module Communications Network . No GO to E6 - E6 CHECK FOR IPC (INSTRUMENT PANEL CLUSTER) DTC (DIAGNOSTIC TROUBLE CODE) S
- Ignition OFF.
- Ignition ON.
- Using a diagnostic scan tool, carry out the IPC module self-test.
Are any DTC s present?
Yes DIAGNOSE any IPC DTCs. REFER to: Instrument Panel Cluster (IPC) . No The system is operating correctly at this time. The concern may have been caused due to high network traffic or an intermittent fault condition.
