Pinpoint Test 14: The Safety Belt Warning Indicator Is Never/Always On
PINPOINT TEST 14: 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 or the message is deemed invalid by the instrument cluster for greater than 5 seconds, the instrument cluster sets DTC U0151 and defaults the safety belt warning indicator off.
Possible Causes
- RCM
- Instrument cluster
