Pinpoint Test Z : The Powertrain Malfunction (Wrench) Warning RTT (RECONFIGURABLE Telltale) Indicator Is Never Or Always On
- Normal Operation and Fault Conditions
See Powertrain Malfunction (Wrench) Warning. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the transmission service required, engine service required or body service required message is missing for less than 5 seconds, the IPC defaults the powertrain malfunction (wrench) warning RTT indicator to the last indication state (on or off), based upon the last message received.
If the transmission service required, engine service required or body service required message is missing for 5 seconds or longer, the IPC defaults the powertrain malfunction (wrench) warning RTT indicator 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 Z2 No GO to Pinpoint Test A - Z2 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to the IPC DTC Chart. Refer to Diagnostic Trouble Code (DTC) Chart No GO to Z3 - Z3 PERFORM THE BCM (BODY CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the BCM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Body Control Module (BCM) . No GO to Z4 - Z4 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 powertrain malfunction (wrench) RTT warning indicator is never on, the system is operating correctly at this time. There are currently no vehicle concerns present that require the powertrain malfunction (wrench) RTT warning indicator display. If the powertrain malfunction (wrench) RTT warning indicator is always on, DIAGNOSE all PCM Diagnostic Trouble Codes (DTCs). REFER to: Electronic Engine Controls .
