Pinpoint Test - Supplemental Restraint System (SRS)
Pinpoint Test T: DTC B00A0:97
Refer to Wiring Diagram Set 46 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Supplemental Restraint System for schematic and connector information. Diagrams By Number
Normal Operation
The Occupant Classification System Module (OCSM) monitors each Occupant Classification Sensor (OCS) weight sensor bolt and circuitry for faults. If the OCSM detects an upward force (obstruction) on the passenger seat for 60 seconds, it will store DTC B00A0:97 in memory and send a message to the Restraints Control Module (RCM).
The RCM will store DTC B00A0:09 in memory and send a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.
- DTC B00A0:97 (Occupant Classification System: Component or System Operation Obstructed or Blocked) - If the OCSM detects a negative force on one or more OCS weight sensor bolt(s), it will set this DTC.
This pinpoint test is intended to diagnose the following:
- Foreign object placed under or contacting the passenger seat
PINPOINT TEST T: DTC B00A0:97
WARNING: Never probe the electrical connectors on air bag, Safety Canopy(R) 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 safety belt buckle/retractor pretensioners or adaptive load limiting retractors or probe the electrical connectors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test. Inspection and Verification
NOTE: Supplemental Restraint System (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: The OCS weight sensor bolt(s) are 3 wire sensors and cannot be tested using a multi-meter.
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 Catalog Advantage(TM) 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.
-------------------------------------------------
T1 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 T2.
No
This is an intermittent fault when present as a CMDTC only. GO to T4.
-------------------------------------------------
T2 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(s) at or near the OCS weight sensor bolts for correct routing.
- Were any problems noted?
Yes
REMOVE obstruction and/or REPAIR as necessary. GO to T5.
No
GO to T3.
-------------------------------------------------
T3 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) Service and Repair. GO to T5.
No
In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. SRS components should only be installed when directed to do so in the pinpoint test. GO to T4.
-------------------------------------------------
T4 CHECK FOR AN INTERMITTENT FAULT
- 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 during the on-demand self test. GO to T2.
No
CHECK for causes of the intermittent fault. Do not install any new SRS components at this time. SRS components should only be installed when directed to do so in the pinpoint test. REPAIR any intermittent wiring, terminal or connector concerns found.
GO to T5.
-------------------------------------------------
T5 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 notprove out the SRS at this time. Refer to Supplemental Restraint System (SRS) Depowering and Repowering 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 will be retrieved from the RCM and OCSM.
- Are any RCM and/or OCSM 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. [1][2]Diagnostic Trouble Code Descriptions
No
CLEAR all RCM and OCSM CMDTCs. PROVE OUT the SRS. Repair is complete. RETURN the vehicle to the customer.
