Pinpoint Test M - DTC: B00D5:11, B00D5:12 and B00D5:13

Refer to Supplemental Restraint System for schematic and connector information.

Normal Operation and Fault Conditions

The RCM briefly activates each LED in the PAD indicator to prove-out and verify correct functional operation of the PAD indicator to the occupants.

The RCM monitors the PAD indicator power supply and "OFF" LED circuits for the following faults:

Open circuit
Short to voltage
Short to ground
Faulted PAD indicator

If 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

DTC	Description	Fault Trigger Conditions
B00D5:11	Restraint System Passenger Disable Indicator: Circuit Short to Ground	A fault is indicated when the RCM senses a short to ground on the PAD indicator "OFF" LED circuit.
B00D5:12	Restraint System Passenger Disable Indicator: Circuit Short to Battery	A fault is indicated when the RCM senses a short to voltage on the PAD indicator "OFF" LED circuit.
B00D5:13	Restraint System Passenger Disable Indicator: Circuit Open	A fault is indicated when the RCM senses an open on the PAD indicator "OFF" LED circuit. An open on the ignition voltage supply circuit to the PAD indicator also sets this DTC.

Possible Causes

Wiring, terminals or connectors
PAD indicator
RCM

Visual Inspection and Diagnostic Pre-checks

Verify BCM fuse 86 (10A) is OK.

PINPOINT TEST A : B00D5:11, B00D5:12 AND B00D5:13

WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
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 components 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 parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

No GO to A9

A9 CONFIRM THE RCM (RESTRAINTS CONTROL MODULE) FAULT

NOTE: Make sure all SRS components and the RCM electrical connectors are connected before carrying out the self-test. If not, Diagnostic Trouble Codes (DTCs) will be recorded.

Ignition OFF.

Depower the SRS. Refer to: Supplemental Restraint System (SRS) Depowering .

Prior to reconnecting any previously disconnected SRS component:
- inspect connector(s) (including any inline connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals.
- inspect wire harness for any damaged, pinched, cut or pierced wires.
- inspect RCM C310A and C310B Connector Position Assurance (CPA) lever/lock for correct operation.
- repair any concerns found. Refer to Connector Repair Procedures for schematic and connector information.

Connect: PAD Indicator C2286 .

Connect: RCM C310A and C310B .

Repower the SRS.
Do not prove out the SRS at this time. Refer to: Supplemental Restraint System (SRS) Repowering .

Ignition ON.

Using a diagnostic scan tool, perform RCM self-test.

Was the original DTC retrieved on-demand during self-test?

Yes	CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new RCM. Refer to: Restraints Control Module (RCM) . Go to A11

No	In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test. GO to A10

A10 CHECK FOR AN INTERMITTENT FAULT

Ignition OFF.

Connect: PAD Indicator C2286 (if previously disconnected).
- Inspect connector(s) (including any inline connectors) for corrosion, loose or spread terminals and loose or frayed wire connections at terminals.
- Inspect wire harness for any damage, pinched, cut or pierced wires.

- Repair any concerns found. Refer to Connector Repair Procedures for schematic and connector information.

Connect all previously disconnected component(s) / connector(s).

Ignition ON.

Using a diagnostic scan tool, perform RCM self-test.

Was DTC B00D5:11, B00D5:12 or B00D5:13 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 DTC B00D5:11, GO to A2. For DTC B00D5:12, GO to A7. For DTC B00D5:13, GO to A4

CHECK for causes of intermittent open, short to ground or short to voltage on the PAD indicator circuit. 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. Install SRS components only when directed to do so in the pinpoint test. GO to A11

A11 CHECK FOR ADDITIONAL SRS (SUPPLEMENTAL RESTRAINT SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS)

Ignition OFF.

Reconnect all SRS components (if previously disconnected).

If previously directed to depower the SRS, repower the SRS.

Ignition ON.

NOTE: When selecting Restraints from the Self Test menu, DTCs are retrieved from the RCM and OCSM.

Using a diagnostic scan tool, perform

Restraints self-test.

Are any RCM and/or OCSM Diagnostic Trouble Codes (DTCs) retrieved on-demand during self-test?

Yes	Do not clear any Diagnostic Trouble Codes (DTCs) until all Diagnostic Trouble Codes (DTCs) have been resolved. DIAGNOSE and REPAIR the RCM and/or OCSM Diagnostic Trouble Codes (DTCs). Refer to: Airbag Supplemental Restraint System (SRS) .
