Pinpoint Test Aw : The Hazard RTT (RECONFIGURABLE Telltale) Indicator Is Never Or Always On (Hybrid)

Normal Operation and Fault Conditions
See HEV Hazard. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .

If the HEV battery warning indicator request or the HEV transmission warning indicator request message is missing for less than 5 seconds, the IPC defaults the hazard RTT indicator to the last indication state (on or off), based upon the last message received.

If the HEV battery warning indicator request or the HEV transmission warning indicator request message is missing for 5 seconds or longer, the IPC defaults the hazard RTT indicator on.

AW1 CHECK THE MESSAGE CENTER OPERATION
- Ignition 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 AW2

No GO to Pinpoint Test A

AW2 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 AW3

AW3 PERFORM 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 ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID)

No GO to AW4

AW4 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 .

If the hazard RTT indicator is never on, the system is operating correctly at this time. There are currently no vehicle concerns present that require the hazard RTT indicator. If the hazard RTT indicator is always on, DIAGNOSE any BECM Diagnostic Trouble Codes (DTCs). REFER to the appropriate High Voltage Battery article.
