Test F: Safety Belt Warning Indicator Is Never/Always On

Pinpoint Test F: The Safety Belt Warning Indicator Is Never/Always On

Normal Operation
The safety belt switch is hardwired to the restraint control module (RCM). The instrument cluster receives the safety belt switch status from the RCM over the high speed controller area network (HS-CAN). The RCM signals the instrument cluster, when the safety belt is unfastened, to illuminate the safety belt warning indicator.

Possible Causes
- RCM
- instrument cluster
