D6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0140:XX OR U0422:XX SET IN OTHER MODULES
Using a diagnostic scan tool, carry out the self-test for all modules. Retrieve and record the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0140:xx or U0422:xx set in 1 or more modules in addition to the ABS module?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Click here to access Guided Routine (BCM). |

No | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern and DTC U0140:00 was set by the ABS module, INSTALL a new ABS module. REFER to: Anti-Lock Brake System (ABS) Module (206-09 Anti-Lock Brake System (ABS) and Stability Control, Removal and Installation). |
The Traction Control System Cannot Be Disabled
Refer to Wiring Diagrams Cell 60 for schematic and connector information.
NOTE: This test requires the use of at least 2 keys programmed to the vehicle, one admin key and one restricted 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 HS-CAN2. The ABS module continues to monitor for excessive wheel spin, but no longer takes any action when a traction event is detected.
The ABS module then sends a message to the GWM over the HS-CAN2 to illuminate the stability-traction control disabled indicator (sliding car OFF icon). The GWM relays this message to the IPC over the HS-CAN3. The IPC responds by illuminating the stability-traction control disabled indicator (sliding car OFF icon). The traction control system remains deactivated until the driver changes the traction control state in the message center or until the ignition is cycled.
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 AdvanceTrac® always on feature configured to "on", the traction control system cannot be disabled. An admin key must be used to enable and disable the traction control system.
