The Restraints Control Module (RCM) is in constant communication with various control modules on the High Speed Controller Area Network (HS-CAN), one of them is the Occupant Classification System Module (OCSM). The RCM continuously monitors the HS-CAN for fault messages reported by the Occupant Classification System (OCS) system. The RCM also checks for the correct identification of the OCSM. If the RCM receives fault message(s) from the OCS system, it will store DTC B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
This pinpoint test is intended to diagnose the following:
- OCSM
- RCM
DTC DESCRIPTION TABLE
| DTC Description | Fault Trigger Condition |
|---|---|
|
When the RCM receives a message from the OCSM that a fault exists within the OCS system, a fault will be indicated. |
|
When the RCM senses the OCS system is present but not configured, a fault will be indicated. |
|
When the RCM receives 8 or more invalid states from the OCSM, a fault will be indicated. |
|
When the RCM receives messages containing upper or lower data limits other than limits stored in memory, a fault will be indicated. |
|
When the RCM receives a message containing incorrect data, a fault will be indicated. |
