Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pinpoint Test L: OCS Faults Reported By RCM: Notes
Refer to appropriate Supplemental Restraint System in OEM Wiring Diagrams article, for schematic and connector information.
Normal Operation and Fault Conditions
The RCM is in constant communication with various control modules on the HS-CAN 2. One of those modules is the OCSM. The RCM continuously monitors the HS-CAN 2 for fault messages reported by the OCSM. The RCM also checks for the correct identification of the OCSM. If the RCM receives fault message(s) from the OCSM, it stores DTC B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 in memory and sends a message to the IPC to illuminate the airbag warning indicator.
PPT L RCM DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B00A0:09 | Occupant Classification System: Component Failure | Sets when the RCM receives a message from the OCSM that a fault exists within the OCS. |
| B00A0:4A | Occupant Classification System: Incorrect Component Installed | Sets when the RCM senses the OCSM is present but not configured. |
| B00A0:63 | Occupant Classification System: Circuit / Component Protection Time- Out | Sets when the RCM receives 8 or more invalid states from the OCSM. |
| B00A0:64 | Occupant Classification System: Signal Plausibility Failure | Sets when the RCM receives messages containing upper or lower data limits other than limits stored in memory. |
| B00A0:68 | Occupant Classification System: Event Information | Sets when the RCM receives a message from the OCSM that indicates an OCS fault is present. |
