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

PINPOINT TEST R: THE SAFETY BELT WARNING INDICATOR IS NEVER/ALWAYS ON

Normal Operation
The restraints control module (RCM) monitors the safety belt position through the safety belt buckle switch. The RCM provides the safety belt buckle status to the instrument cluster over the high speed controller area network (HS-CAN) communication bus. If the instrument cluster does not receive the safety belt buckle switch status from the RCM for greater than 5 seconds, the instrument cluster sets DTC U0151 and defaults the safety belt warning indicator off. If the RCM message is deemed invalid by the instrument cluster for greater than 5 seconds, the instrument cluster sets DTC U2023 and defaults the safety belt warning indicator off.

This pinpoint test is intended to diagnose the following:
- RCM
- Instrument cluster
