PINPOINT TEST AB: DTCs B00A0:54, B00A0:76, B00C2:49 AND B00C3:49

WARNING: This page is about a different car, the 2013 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

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.

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.

NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.

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 Supplemental Restraint System (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: Do not install any new OCS components until directed to do so. OCS components should only be installed when directed to do so in the pinpoint test.

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 parts catalog 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.

AB1 CHECK FOR ADDITIONAL OCS DTCs
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - OCSM.
- Were any DTCs other than B00A0:54, B00A0:76, B00C2:49 or B00C3:49 retrieved during the self-test?
- Yes : REPAIR the DTCs before continuing with this test. REFER to the OCSM DTC Chart .
- No : GO to AB2.
AB2 CHECK THE SEAT WIRING AND CONNECTORS
- Ignition OFF.
  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.
- Carry out a thorough inspection of the OCS wiring, terminals and connectors and the related seat wiring harness and body wiring harness terminals and connectors. Inspect the passenger seat wire harness for correct routing and retention. Refer to Seat Wire Harness Routing in the general procedures portion of SEAT SYSTEM - SEATS .
- NOTE: The OCS weight sensor bolts do not have differently keyed connectors. Connecting the incorrect connector to a sensor causes DTCs to set.
  
  Use the wire colors for correct weight sensor bolt connection. Refer to SYSTEM WIRING DIAGRAMS - Supplemental Restraint System for schematic and connector information.
  
  Confirm that the sensors are connected correctly
  - OCS weight sensor bolt "C" is located at the rear of the inboard seat track
  - OCS weight sensor bolt "D" is located at the front of the inboard seat track

- Were any problems noted?
- Yes : REPAIR the seat connectors and wiring as needed. Refer to OEM Wiring Diagrams - Connector Repair Procedures for schematic and connector information. REFER to SEAT SYSTEM - SEATS for wire harness routing information. CARRY OUT the Occupant Classification System (OCS) Reset. REFER to OCCUPANT CLASSIFICATION SENSOR (OCS) SYSTEM RESET . GO to AB4.
- No : GO to AB3.
AB3 CHECK THE SEAT TRACK
NOTE: Check for a bent or binding seat track assembly. Position the seat in all positions and check for correct operation after installation of the seat into the vehicle. Failure to follow this instruction may result in an unsuccessful system reset and incorrect operation of the Occupant Classification System (OCS).

NOTE: The passenger seat bolts must be tightened to the correct specifications and in the correct sequence. Refer to SEAT SYSTEM - SEATS Seat - Front in Removal and Installation for the correct sequence. Failure to follow this instruction may result in an unsuccessful system reset and incorrect operation of the Occupant Classification System (OCS).
- For vehicles with a manual seat, adjust the seat position to the full forward position of seat travel, then back to the mid-point of the seat track travel.
- Loosen the 4 seat track-to-floor mounting bolts.
- Tighten the seat track-to-floor bolts in the correct sequence. Refer to SEAT SYSTEM - SEATS Seat - Front in Removal and Installation for the torque sequence.
- Carry out the Occupant Classification System (OCS) Reset. Refer to OCCUPANT CLASSIFICATION SENSOR (OCS) SYSTEM RESET .
- If the System Reset successfully completed, carry out the Occupant Classification System (OCS) Zero Seat Weight Test. Refer to OCCUPANT CLASSIFICATION SENSOR (OCS) SYSTEM ZERO SEAT WEIGHT TEST .
- Did the system reset and zero seat weight test pass?
- Yes : Fault corrected. GO to AB4.
- No : INSTALL a new passenger seat track assembly with OCS weight sensor bolts. GO to AB4.
AB4 CHECK FOR ADDITIONAL SRS DTCs
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - Restraints.
  NOTE: When selecting Restraints from the Self Test menu, DTCs are retrieved from the RCM and OCSM.
- Are any RCM and/or OCSM DTCs retrieved on-demand during self-test?
- Yes : Do not clear any DTCs until all DTCs have been resolved. GO to the DTC CHARTS for pinpoint test direction.
- No : CLEAR all RCM and OCSM CMDTCs. PROVE OUT the SRS. The repair is complete. RETURN the vehicle to the customer.
