Pinpoint Test Ac: DTC B00A0:97

WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy® or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, 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: 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 OCS weight sensor bolt(s) are 3 wire sensors and cannot be tested using a multi-meter.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  1. AC1 RETRIEVE OCSM DTCs 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - OCSM.
    • Was DTC B00A0:97 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 self-test. GO to  AC2.
      • No  : This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to  AC6.
  2. AC2 INSPECT UNDER THE PASSENGER SEAT FOR FOREIGN OBJECTS AND CORRECT WIRE HARNESS ROUTING 
    • Ignition OFF.
    • Carry out a thorough inspection:
      • under the passenger seat for the presence of any foreign object(s) making contact with the seat cushion or track.
      • on the side of the passenger seat for foreign objects contacting the side of the seat (between console and seat).
      • of the passenger seat and body wire harness(es) at or near the OCS weight sensor bolts for correct routing. Refer to Seat Wire Harness Routing in the General Procedures portion of SEATING .
    • 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.
    • Remove any obstructions and/or repair any items that did not pass inspection.
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Clear All Continuous Memory Diagnostic Trouble Codes (CMDTCs).
    • Enter the following diagnostic mode on the scan tool: Self Test - OCSM.
    • Was DTC B00A0:97 retrieved again during the self-test? 
      • Yes  : GO to  AC3.
      • No  : The fault is not present at this time and may have been caused by an obstruction, mis-aligned manual seat track, or incorrect wire routing. GO to  AC7.
  3. AC3 CARRY OUT THE ZERO SEAT WEIGHT TEST 
    • Carry out the OCS Zero Seat Weight Test. Refer to Occupant Classification Sensor (OCS) System Zero Seat Weight Test  .
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Clear All Continuous Memory Diagnostic Trouble Codes (CMDTCs).
    • Enter the following diagnostic mode on the scan tool: Self Test - OCSM.
    • Was DTC B00A0:97 retrieved again during the self-test? 
      • Yes  : GO to  AC4.
      • No  : The fault is not present at this time and may have been caused due to a mis-calibrated passenger seat OCSM. GO to  AC7.
  4. AC4 CHECK THE OCS SENSOR STATUS PID (OCS_SENSTAT) 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Data Logger - RCM.
    • Monitor the RCM PID (OCS_SENSTAT).
    • Does the PID display "Indeterminate"? 
  5. AC5 CONFIRM THE OCSM FAULT 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - OCSM.
    • Was DTC B00A0:97 retrieved on-demand during self-test? 
      • Yes  : INSTALL a new OCSM. REFER to Occupant Classification System Module (OCSM)  . GO to  AC7.
      • No  : In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test  . GO to  AC6.
  6. AC6 CHECK FOR AN INTERMITTENT FAULT 
    • Ignition OFF.
    • Carry out a thorough inspection:
      • under the passenger seat for the presence of any foreign object(s) making contact with the seat cushion or track.
      • on the side of the passenger seat for foreign objects contacting the side of the seat (between console and seat).
      • of the passenger seat and body wire harness(es) at or near the OCS weight sensor bolts for correct routing. Refer to Seat Wire Harness Routing in the General Procedures portion of SEATING .
    • 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.
    • Remove any obstructions and/or repair any items that did not pass inspection.
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - OCSM.
    • Was DTC B00A0:97 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 self-test. GO to  AC2.
      • No  : CHECK for causes of the intermittent fault. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test  . REPAIR any intermittent concerns found. GO to  AC7.
  7. AC7 CHECK FOR ADDITIONAL SRS DTCs 
    • 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.
    • Reconnect all SRS components (if previously disconnected).
    • If previously directed to depower the SRS, repower the SRS. Do not prove out the SRS at this time. Refer to Supplemental Restraint System (SRS) Depowering and Repowering  .
    • 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.
