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

- Disconnect and inspect all RCM connectors.
- 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 RCM connectors. Make sure they seat and latch 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 RCM. REFER to RESTRAINTS CONTROL MODULE (RCM) . 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.
