Pinpoint Test - DTC: N
B00A0:09, B00A0:4A, B00A0:63, B00A0:64 and B00A0:68
Refer to Wiring Diagrams Cell 46 for schematic and connector information.
Normal Operation and Fault Conditions
The RCM is in constant communication with various control modules on the High Speed Controller Area Network 2 (HS2-CAN). One of those modules is the OCSM. The RCM continuously monitors the High Speed Controller Area Network 2 (HS2-CAN) 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.
DTC Fault Trigger Conditions
Description | Fault Trigger Conditions | |||
|---|---|---|---|---|
DTC | ||||
B00A0:09 | Occupant Classification System: Component Failure | A fault is indicated when the RCM receives a message from the OCSM that a fault exists within the OCS. | ||
B00A0:4A Occupant Classification System: Incorrect Component Installed | A fault is indicated when the RCM senses the OCSM is present but not configured. | |||
B00A0:63 | Occupant Classification System: Circuit / Component Protection Time-Out | A fault is indicated when the RCM receives 8 or more invalid states from the OCSM. | ||
B00A0:64 | Occupant Classification System: Signal Plausibility Failure | A fault is indicated when the RCM receives messages containing upper or lower data limits other than limits stored in memory. | ||
B00A0:68 | Occupant Classification System: Event Information | A fault is indicated when the RCM receives a message from the OCSM that indicates an OCS fault is present. | ||

PINPOINT TEST A : B00A0:09, B00A0:4A, B00A0:63, B00A0:64 AND B00A0:68
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
