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

- Ignition ON.
- Press the auto stop-start switch on and off and verify the status indicator in the switch illumination operates correctly.
Does the switch illuminate when pressed and turn off when pressed again?
Yes GO to M2 No DIAGNOSE the auto stop-start switch. or REFER to: Climate Control System - Vehicles With: Electronic Automatic Temperature Control (EATC) . - M2 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: Instrument Panel Cluster (IPC) No GO to M3 - M3 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 ELECTRONIC ENGINE CONTROLS (1.0L) or refer to ELECTRONIC ENGINE CONTROLS (2.0L) No GO to M4 - M4 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 No GO to M5 - M5 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) INDICATOR LAMP CONTROL ACTIVE COMMAND USING A SCAN TOOL
- Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).
- Select the IPC all lamps (ALL_LAMP) PID.
- Command all the indicators on then off. Observe the auto stop-start indicator.
Does the auto stop-start indicator turn on when commanded on and turn off when commanded off?
Yes DIAGNOSE the auto stop-start system. No INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) .
