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: SRS components should only be disconnected or reconnected 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.
A1 RETRIEVE OCSM (OCCUPANT CLASSIFICATION SYSTEM MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
WARNING: Before beginning any service procedure in this section, refer to Safety Warnings in section 100-00 General Information. Failure to follow this instruction may result in serious personal injury.
REFER to: Health and Safety Precautions (100-00 General Information, Description and Operation). Ignition ON. Using a diagnostic scan tool, perform OCSM self-test.
Was DTC B00C2:11 or B00C2:12 retrieved on-demand during self-test?
Yes | This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during the self-test. For DTC B00C2:11, GO to A2 For DTC B00C2:12, GO to A4 |
|---|---|
No | This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to A6 |
A2 CHECK THE BELT TENSION SENSOR (BTS)
NOTE: This pinpoint test step attempts to change the fault reported by the OCSM by inducing a different fault condition. If the fault reported changes, this indicates the OCSM is functioning correctly and is not the source of the fault.
Ignition OFF. Disconnect Passenger Safety Belt Buckle C3238. Using a diagnostic scan tool, perform OCSM self-test. DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the Belt Tension Sensor (BTS) disconnected, an open circuit fault is normally retrieved. The Belt Tension Sensor (BTS) shares a connector with the passenger safety belt buckle switch, and a passenger safety belt buckle switch circuit fault will also be present in the RCM.
Was DTC B00C2:11 retrieved on-demand during self-test?
Yes | GO to A3 |
|---|---|
No | INSTALL a new passenger safety belt buckle. REFER to: Front Seatbelt Buckle (501-20A Seatbelt Systems, Removal and Installation). GO to A7 |
A3 CHECK THE BELT TENSION SENSOR (BTS) VREF CIRCUIT FOR A SHORT TO GROUND
WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
