Normal Operation and Fault Symptoms
The RCM briefly activates the PAD indicator to confirm and verify correct functional operation of the passenger PAD indicator.
The RCM monitors the PAD indicator circuits for the following faults:
Open circuit
Short to voltage
Short to Ground
PAD Fault Indicator
When a fault is detected, the RCM stores DTC B00D5:11, B00D5:12 or B00D5:13 in memory and sends a message to the IPC to illuminate the airbag warning indicator.
DTC Fault Trigger Conditions
Trouble Code
Description
Fault Trigger Conditions
B00D5:11
Driver Seat Belt Sensor: Short to Ground
The fault is indicated when the RCM detects a short to ground in the PAD indicator circuit.
B00D5:12
Driver Seat Belt Sensor: Short to Battery
The fault is indicated when the RCM detects a short to battery voltage in the PAD indicator circuit.
B00D5:13
Driver Seat Belt Sensor: Open Circuit
The fault is indicated when the RCM detects an open in the PAD indicator circuit. An open in the ignition voltage supply to the PAD indicator also sets this DTC.
Possible Causes
Wiring, Terminals or Connectors

RCM
Visual Inspection and Preliminary Diagnosis
Check that CJB fuse 4 (7.5A) is serviceable.
PINPOINT TEST A: B00D5:11, B00D5:12 AND B00D5:13
NOTE: Most concerns are related to connector and/or wiring issues. Perform a thorough inspection and check before proceeding to the Pinpoint Test.
NOTE: Only disconnect or reconnect SRS components when instructed to do so in the Pinpoint Test step. Failure to follow this instruction may result in an incorrect SRS diagnosis.
NOTE: Always verify the correct SRS component is installed. Parts released for other vehicles may be incompatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to confirm the correct component is installed. If an incorrect SRS component is installed, diagnostic trouble codes (DTCs) may be set.
NOTE: Before returning the vehicle to the customer, the SRS must be fully functional and operating correctly.

Ignition OFF. WARNING: Turn the ignition OFF and wait one minute to discharge the backup power supply. Failure to follow this instruction may result in serious injury or death in the event of an accidental deployment.
Connect: PAD Indicator C2286.
Inspect the connector(s) (including any inline connectors) for corrosion, loose or spread terminals, and loose or worn wire-to-terminal connections.
Inspect the wiring harness for damage, pinching, cut or pierced wires.
Inspect the RCM C310A and C310B connector position assurance (CPA) lever/latch for proper operation.
Rectify any concerns found. Refer to Wiring Diagrams Cell 05 for schematic and connector information.
Reconnect all previously disconnected components/connectors.
The ignition is on.
Using the diagnostic scanner, perform the RCM self-test.
Was DTC B00D5:11, B00D5:12 or B00D5:13 retrieved on-demand during the self-test?
Yes
This condition cannot be resolved until it is repaired and the DTC is no longer retrieved on demand during self-test. For DTC B00D5:11 GO to A2. For DTC B00D5:12 GO to A7. For DTC B00D5:13 GO to A4.
No
CHECK for intermittent open, short to ground or short to voltage in the PAD indicator circuit. TRY to recreate the intermittent fault by flexing the wiring harness and cycling the ignition frequently. ACTIVATE other systems on the same harness. Do not install any new SRS components at this time. Install SRS components only if directed by a pinpoint test. GO to A11.
Ignition OFF. WARNING: Turn the ignition OFF and wait one minute to discharge the backup power supply. Failure to follow this instruction may result in serious injury or death in the event of an accidental deployment.
Reconnect all SRS components (if previously disconnected).
If previously instructed to disable the SRS, re-enable the SRS. Do not check the SRS at this time. Refer to: Supplemental Restraint System (SRS) Disabling and Arming (501-20B Supplemental Restraint System, General Procedures).
The ignition is on.
NOTE: When Restraints is selected in the Self Test menu, DTCs are retrieved from the RCM and OCSM. Using the diagnostic scanner, perform the Restraints Self Test.
Are any RCM and/or OCSM Diagnostic Trouble Codes (DTCs) retrieved on demand during the self-test?
Yes
Do not clear any Diagnostic Trouble Codes (DTCs) until all DTCs have been resolved. DIAGNOSE and REPAIR the RCM and/or OCSM DTCs. Refer to: Supplemental Restraint System (SRS) (501-20B).
