Normal Operation
The Restraints Control Module (RCM) is in constant communication with various control modules on the High Speed Controller Area Network (HS-CAN), one of them is the Occupant Classification System Module (OCSM). The RCM (Restraints Control Module) continuously monitors the HS-CAN (High Speed Controller Area Network) for fault message reported by the Occupant Classification System (OCS) system. The RCM (Restraints Control Module) also checks for the correct identification of the OCSM (Occupant Classification System Module). If the RCM (Restraints Control Module) detects one of the following faults reported by the OCS (Occupant Classification System) system, it will store DTC B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 in memory and send a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.
This pinpoint test is intended to diagnose the following:
- OCSM (Occupant Classification System Module)
- RCM (Restraints Control Module)
PINPOINT TEST R : DTCs B00A0:09, B00A0:4A, B00A0:63, B00A0:64 and B00A0:68
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM 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: Always tighten the fasteners of the restraints control module (RCM) and impact sensor (if equipped) to the specified torque. Failure to do so may result in incorrect restraint system operation, which increases the risk of personal injury or death in a crash.
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 (Supplemental Restraint System).
NOTE: 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: Always make sure the correct Supplemental Restraint System (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) or equivalent to make sure the correct component is being installed. If an incorrect SRS (Supplemental Restraint System) component is installed, DTCs may set.
NOTE: The SRS (Supplemental Restraint System) must be fully operational and free of faults before releasing the vehicle to the customer.
R1 RETRIEVE RCM (Restraints Control Module) DTCs
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test- RCM (Restraints Control Module).
Was DTC B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 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.
For DTCs B00A0:09, B00A0:63 and B00A0:68, RETRIEVE DTCs from the OCSM (Occupant Classification System Module) and REFER to the Occupant Classification System Module (OCSM) DTC chart for diagnostic direction Air Bag Systems.
For DTC B00A0:4A or B00A0:64, GO to R2.
No
CHECK for causes of the intermittent fault.
Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information Electrical Diagrams.
ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition frequently. Do not install any new SRS (Supplemental Restraint System) components at this time. SRS (Supplemental Restraint System) components should only be installed when directed to do so in the pinpoint test. GO to R5.
R2 CHECK THE OCS (Occupant Classification System)
- 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.
- Verify the correct OCS (Occupant Classification System) system service kit has been installed in the vehicle.
Is the correct OCS (Occupant Classification System) system service kit installed?
Yes
GO to R3.
No
INSTALL the correct OCS (Occupant Classification System) system service kit. REFER to Occupant Classification Sensor - Service Kit . GO to R5.
R3 CHECK THE RCM (Restraints Control Module)
- Ignition OFF.
- Verify the correct RCM (Restraints Control Module) has been installed.
Is the correct RCM (Restraints Control Module) installed?
Yes
GO to R4.
No
INSTALL the correct RCM (Restraints Control Module). REFER to Restraints Control Module (RCM) . GO to R5.
R4 CHECK THE RCM (Restraints Control Module)
- Ignition ON.
- Carry out Programmable Module Installation (PMI) for the RCM (Restraints Control Module) Programming and Relearning. Manually enter as-built data. Refer to Information Bus.
- Enter the following diagnostic mode on the scan tool: Self Test- RCM (Restraints Control Module).
Was DTC B00A0:4A or B00A0:64 retrieved on-demand during self-test?
Yes
INSTALL a new RCM (Restraints Control Module). REFER to Restraints Control Module (RCM) . GO to R5.
No
Fault corrected. GO to R5.
R5 CHECK FOR ADDITIONAL SRS (Supplemental Restraint System) 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 (Supplemental Restraint System) components (if previously disconnected).
- 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 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 (Restraints Control Module) and OCSM (Occupant Classification System Module).
Are any RCM (Restraints Control Module) and/or OCSM (Occupant Classification System Module) 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 Air Bag Systems.
No
CLEAR all RCM (Restraints Control Module) and OCSM (Occupant Classification System Module) DTCs. PROVE OUT the SRS (Supplemental Restraint System). Repair is complete. RETURN the vehicle to the customer.
