Pinpoint Test Aw: The SEATBELT Warning Indicator Or RTT (RECONFIGURABLE Telltale) Warning Indicator Is Never Or Always On
- Normal Operation and Fault Conditions
See Seatbelt Warning. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the driver seatbelt buckle status or passenger seatbelt buckle status message is missing for less than 5 seconds, the IPC defaults the seatbelt warning indicator or RTT indicator to its last indication state (on or off), based upon the last message received.
If the driver seatbelt buckle status or passenger seatbelt buckle status message is missing for 5 seconds or longer, the IPC defaults the seatbelt warning indicator or RTT warning indicator off.

- AW1 IDENTIFY THE IPC (INSTRUMENT PANEL CLUSTER) LEVEL
- Determine if the vehicle is equipped with a 4-inch display IPC. REFER to: Instrument Panel Cluster (IPC) - Overview .
Is the vehicle equipped with a 4-inch display IPC?
Yes GO to AW3 No GO to AW2 - AW2 CHECK THE MESSAGE CENTER OPERATION
- Ignition ON.
- Close all doors 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 AW3 No GO to Pinpoint Test A - AW3 CHECK THE SEATBELT BUCKLE STATUS
- Using a diagnostic scan tool, view the RCM Parameter Identifications (PIDs).
- For driver seatbelt,
Access the RCM and monitor the SBELT_D_STPID
- For passenger seatbelt,
Access the RCM and monitor the SBELT_P_STPID
- Monitor the RCM seatbelt buckle Parameter Identifications (PIDs) while buckling and unbuckling the driver or passenger seatbelt.
Does the PID display BUCKLED with the seatbelt buckled and UNBUCKLED with the seatbelt unbuckled?
Yes For 4-inch display IPC, GO to AW4 For 8-inch or 12-inch display IPC, GO to AW5 No INSTALL a new seatbelt buckle. REFER to: Front Seatbelt Buckle . - AW4 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) INDICATOR LAMP CONTROL ACTIVE COMMAND
- Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).
- Access the IPC and control the W_SBLTPID
- Command the seatbelt warning indicator on and off while observing the seatbelt warning indicator.
Does the seatbelt warning indicator illuminate when commanded on and turn off when commanded off?
Yes GO to AW5 No GO to AW7 - AW5 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 the IPCDTC Chart. No GO to AW6 - AW6 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: Controller Area Network (CAN) Module Communications Network . No DIAGNOSE all RCM Diagnostic Trouble Codes (DTCs). REFER to the Master DTC Chart. - AW7 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.
