Pinpoint Test P: The Auto Stop-Start Indicator Or RTT (RECONFIGURABLE Telltale) Indicator Is Never Or Always On
- Normal Operation and Fault Conditions
See Auto Stop-Start. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the stop-start standby indicator message is missing for less than 5 seconds, the IPC defaults the auto stop-start warning indicator or auto stop-start RTT indicator to its last indication state (on or off), based upon the last message received.
If the stop-start standby indicator message is missing for 5 seconds or longer, the IPC defaults the auto stop-start warning indicator or auto stop-start RTT warning indicator off.

Using the message center controls, verify the auto stop-start feature is enabled.
Is the auto stop-start system enabled?
Yes GO to P2 No ENABLE the auto stop-start feature and INFORM the customer how to enable the feature. - P2 IDENTIFY THE IPC (INSTRUMENT PANEL CLUSTER) LEVEL
- Determine if the vehicle is equipped with a base IPC. REFER to: Instrument Panel Cluster (IPC) - Overview
Is the vehicle is equipped with a base IPC?
Yes GO to P4 No GO to P3 - P3 CHECK THE MESSAGE CENTER OPERATION
- Ignition ON.
- Close all doors, liftgate and the 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 P5 No GO to Pinpoint Test A - P4 PERFORM 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).
- Access the IPC and control the W_STRTSTP_ENGPID
- Command the auto stop-start indicator on then off.
Does the auto stop-start indicator turn on when commanded on and off when commanded off?
Yes GO to P5 No GO to P8 - P5 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 DTC Chart: IPC. No GO to P6 - P6 PERFORM THE PCM (POWERTRAIN CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the PCM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to the appropriate Electronic Engine Controls article. No GO to P7 - P7 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (CM DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Communications Network No DIAGNOSE the auto stop-start feature. Refer to the appropriate Engine system article for the procedure. - P8 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.
