Pinpoint Test Ac: The Powertrain Malfunction (Wrench) RTT (RECONFIGURABLE Telltale) Indicator Is Never Or Always On
- Normal Operation and Fault Conditions
See Powertrain Malfunction (Wrench) RTT Indicator. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the engine service required, transmission service required, AWD service required or body service required request messages are missing or invalid for less than 5 seconds, the IPC defaults the powertrain malfunction (wrench) RTT indicator to its last state (on or off) based upon the last message received.
If the engine service required, transmission service required, AWD service required or body service required request messages are missing for 5 seconds or longer, the IPC defaults the powertrain malfunction (wrench) RTT indicator on.

Is the door ajar RTT indicator off with the door closed, and on with the door open?
Yes GO to AC2 No GO to Pinpoint Test A - AC2 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM 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 Diagnostic Trouble Code (DTC) Chart . No GO to AC3 - AC3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM 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 the appropriate DTC Chart. No GO to AC5 - AC4 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE SOBDMC (SECONDARY ON-BOARD DIAGNOSTIC CONTROL MODULE C) SELF-TEST
- Using a diagnostic scan tool, perform the SOBDMC self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to the appropriate DTC Chart. No GO to AC5 - AC5 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Controller Area Network (CAN) Module Communications Network . No If the powertrain malfunction (wrench) indicator is always on, DIAGNOSE all PCM Diagnostic Trouble Codes (DTCs). REFER to the appropriate DTC Chart. If the powertrain malfunction (wrench) indicator is never on, the system is operating correctly at this time.
