Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information. Diagrams By Number

Normal Operation

The Restraints Control Module (RCM) monitors all Supplemental Restraint System (SRS) device connections. If the RCM detects a connection or device connected that is not stored in memory or is not configured for the component, the RCM will set a DTC and send a message to the Instrument Panel Cluster (IPC) module to illuminate air bag warning indicator.









This pinpoint test is intended to diagnose the following:
- Incorrect ABS module
- Incorrect OCSM
- Incorrect RCM
- RCM not configured



PINPOINT TEST AH: DTCs B0001:4A, B0002:4A, B0005:4A, B0010:4A, B0011:4A, B0020:4A, B0021:4A, B0028:4A, B0029:4A, B0050:4A, B0052:4A, B0080:4A, B0082:4A, B0090:4A, B0091:4A, B0092:4A, B0095:4A, B0096:4A, B0097:4A, B00B5:4A, B00C5:4A, B00D5:4A, B1212:4A, B1213:4A AND U3000:4A

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: 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 taking 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: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

NOTE: 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: 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) or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

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

-------------------------------------------------
AH1 RETRIEVE RCM DTCs


- Ignition ON.

- Were any incorrect component installed DTCs retrieved?

Yes
This fault cannot be cleared until it is corrected and the DTC is no longer retrieved during self-test. GO to AH2.

No
This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to AH7.

-------------------------------------------------
AH2 CHECK THE VEHICLE HISTORY


- Ignition OFF.
- Check the vehicle repair history.
- Has a new RCM or OCSM been installed during this or a prior repair?

Yes
GO to AH3.

No
GO to AH4.

-------------------------------------------------
AH3 CHECK THE RCM AND OCSM VEHICLE IDENTIFICATION PIDs


- Ignition ON.
- Enter the following diagnostic mode on the scan tool: DataLogger - RCM.
- View and record the following PID values:

AH6 CONFIRM THE RCM FAULT


NOTE: Make sure all restraint system components and the RCM electrical connectors are connected before carrying out the self-test. If not, DTCs will be recorded.

- Ignition OFF.
- Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering Supplemental Restraint System (SRS) Depowering and Repowering.
- Prior to reconnecting any previously disconnected SRS component:

No
CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition frequently. ACTIVATE other systems in the same wire harness. 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 AH8.

-------------------------------------------------
AH8 CHECK FOR ADDITIONAL SRS DTCs
