PINPOINT TEST Z : B0061:11, B0061:12, B0061:13, B0061:1C, and B0061:49

WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.
WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.
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 Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Z1 RETRIEVE OCSM DTCs

Ignition ON.

Using a scan tool, perform OCSM self-test to retrieve DTCs.

Was DTC B0061:11, B0061:12, B0061:13, B0061:1C or B0061:49 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 B0061:11, GO to Z2. For DTC B0061:12, GO to Z5. For DTC B0061:13, GO to Z7. For DTC B0061:1C, GO to Z9. For DTC B0061:49, INSTALL a new OCS sensor. Refer to Occupant Classification System (OCS) Sensor . GO to Z13.
No	This is an intermittent fault when present as a CMDTC only. GO to Z12.

Z2 CHECK THE BTS

NOTE: This pinpoint test step attempts to change the fault reported by the OCSM by inducing a different fault condition. If the reported fault changes, this indicates the OCSM is functioning correctly and is not the source of the fault.

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.

Ignition OFF.

Disconnect Passenger Safety Belt Buckle C3238 .

Using a scan tool, perform OCSM self-test to retrieve DTCs.

DIAGNOSTIC TIP: When viewing DTCs with the BTS disconnected, an open circuit fault is normally retrieved. An open circuit fault is also normally set for the passenger safety belt buckle switch circuit in the RCM.

Was DTC B0061:11 retrieved on-demand during self-test?

Yes	GO to Z3.
No	INSTALL a new passenger safety belt buckle assembly. REFER to Safety Belt System . GO to Z13.

Ignition OFF.

Prior to reconnecting any previously disconnected SRS component:
- inspect connector(s) (including any inline connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals.
- inspect wire harness for any damage, pinched, cut or pierced wires.
- repair any concerns found. Refer to CONNECTOR REPAIR PROCEDURES for schematic and connector information.

Connect OCSM C3159 (if previously disconnected).

Connect Passenger Safety Belt Buckle C3238 (if previously disconnected).

If previously directed to depower the SRS, repower the SRS.
