Diagnostic Overview
B00A0:09, B00A0:4A, B00A0:63, B00A0:64 and B00A0:68
Refer to Wiring Diagram Set 46 for schematic and connector information Electrical Diagrams.
The RCM (Restraints Control Module) is in constant communication with various control modules on the HS-CAN (High Speed Controller Area Network). One of those modules is the OCSM (Occupant Classification System Module). The RCM (Restraints Control Module) continuously monitors the HS-CAN (High Speed Controller Area Network) for fault messages reported by the OCSM (Occupant Classification System Module). The RCM (Restraints Control Module) also checks for the correct identification of the OCSM (Occupant Classification System Module). If the RCM (Restraints Control Module) receives fault message(s) from the OCSM (Occupant Classification System Module) system, it stores DTC (Diagnostic Trouble Code) B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 in memory and sends a message to the IPC (Instrument Panel Cluster) to illuminate the air bag warning indicator.
DTC Fault Trigger Conditions
Pinpoint Test
WARNING: Do not handle, move or change the original horizontal mounting position of the RCM (Restraints Control Module) while the RCM (Restraints Control Module) is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy(R) and cause 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.
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.
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 (Supplemental Restraint System) components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS (Supplemental Restraint System).
NOTE: Always make sure the correct SRS (Supplemental Restraint System) 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 or equivalent to make sure the correct component is being installed. If an incorrect SRS (Supplemental Restraint System) component is installed, DTCs (Diagnostic Trouble Codes) may set.
NOTE: The SRS (Supplemental Restraint System) must be fully operational and free of faults before releasing the vehicle to the customer.
1. RETRIEVE RCM (Restraints Control Module) DTCs (Diagnostic Trouble Codes)
1. Ignition ON.
2. Using a scan tool, perform RCM (Restraints Control Module) self-test to retrieve DTCs (Diagnostic Trouble Codes).
Was DTC (Diagnostic Trouble Code) B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 retrieved on-demand during self-test?
2. VERIFY THE OCSM (Occupant Classification System Module) PART NUMBER
1. Using the Log Viewer function of the scan tool, retrieve and record the OCSM (Occupant Classification System Module) part number.
2. Check the part number recorded against the number listed in the Ford Catalog Advantage or equivalent and verify the correct OCSM (Occupant Classification System Module) is present in the vehicle.
Is the correct OCSM (Occupant Classification System Module) installed?
3. VERIFY THE RCM (Restraints Control Module) PART NUMBER
1. Using the Log Viewer function of the scan tool, retrieve and record the RCM (Restraints Control Module) part number.
2. Check the part number recorded against the number listed in the Ford Catalog Advantage or equivalent and verify the correct RCM (Restraints Control Module) is present in the vehicle.
Is the correct RCM (Restraints Control Module) installed?
4. VERIFY THE RCM (Restraints Control Module) CONFIGURATION
1. Carry out PMI (Programmable Module Installation) for the RCM (Restraints Control Module). Manually enter as-built data. Refer to the scan tool instructions when carrying out PMI (Programmable Module Installation).
2. Using a scan tool, perform RCM (Restraints Control Module) self-test to retrieve DTCs (Diagnostic Trouble Codes).
Was DTC (Diagnostic Trouble Code) B00A0:4A retrieved on-demand during self-test?
5. CHECK FOR ADDITIONAL SRS (Supplemental Restraint System) DTCs (Diagnostic Trouble Codes)
1. Ignition OFF.
2. 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.
3. Reconnect all SRS (Supplemental Restraint System) components (if previously disconnected).
4. If previously directed to depower the SRS (Supplemental Restraint System), repower the SRS (Supplemental Restraint System). Do not prove out the SRS (Supplemental Restraint System) at this time. REFER to Supplemental Restraint System (SRS) Depowering and Repowering - with Intelligent Access (IA) or REFER to Supplemental Restraint System (SRS) Depowering and Repowering - without Intelligent Access (IA) .
5. Using a scan tool, perform Restraints self-test to retrieve DTCs (Diagnostic Trouble Codes).
6. When selecting Restraints from the Self Test menu, DTCs (Diagnostic Trouble Codes) are retrieved from the RCM (Restraints Control Module) and OCSM (Occupant Classification System Module).
Are any RCM (Restraints Control Module) and/or OCSM (Occupant Classification System Module) DTCs (Diagnostic Trouble Codes) retrieved on-demand during self-test?
