Pinpoint Test Oo: B0052:11, B0052:12, B0052:13 And B0052:1D

WARNING: Do not handle, move or change the original horizontal mounting position of the Restraints Control Module (RCM) while the Restraints Control Module (RCM) is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy® and cause 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 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 Catalog Advantage^TM or equivalent 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.

A1 RETRIEVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- WARNING: Before beginning any service procedure in this service information, refer to Safety Warnings in GENERAL INFORMATION . Failure to follow this instruction may result in serious personal injury.
  
  REFER to: SAFETY BELT AND SUPPLEMENTAL RESTRAINT SYSTEM (SRS) HEALTH AND SAFETY PRECAUTIONS .
- Ignition ON.
- Enter the following diagnostic mode: Self Test - RCM .
Was DTC B0052:11, B0052:12, B0052:13 or B0052:1D retrieved on-demand during self-test?
1. Yes : This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during self-test.
  For DTC B0052:11 or B0052:1D, GO to A2
  
  For DTC B0052:12, GO to A4
  
  For DTC B0052:13, GO to A5
2. No : This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to A10
A2 CHECK THE PASSENGER SEATBELT SENSOR DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (SHORT TO GROUND OR CURRENT OUT OF RANGE INDICATED)
NOTE: This pinpoint test step attempts to change the fault reported by the RCM by inducing a different fault condition. If the reported fault changes, this indicates the RCM is functioning correctly and is not the source of the fault.
- Ignition OFF.
- Depower the SRS .
  REFER to: SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Disconnect Passenger Safety Belt Buckle Switch (Inline) C3007J .
- Repower the SRS . Do not prove out the SRS at this time.
  REFER to: SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Ignition ON.
- Enter the following diagnostic mode: Self Test - RCM .
- DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the passenger safety belt buckle switch disconnected, an open circuit fault is normally retrieved. Due to the inline connector being disconnected, a fault is also normally retrieved for the OCS , passenger seat track position sensor and passenger side air bag circuits.
Did the on-demand DTC change from B0052:11 or B0052:1D to B0052:13?
1. Yes : GO to A8
2. No : For DTC B0052:11, GO to A3
  For DTC B0052:1D, GO to A9

A3 CHECK THE PASSENGER SAFETY BELT BUCKLE SWITCH CIRCUIT FOR A SHORT TO GROUND

Ignition OFF.
Depower the SRS .
REFER to: SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .

C3007J-1		Ground

Is any voltage present?

Yes : REPAIR the circuit.
Refer to OEM CONNECTOR REPAIR PROCEDURES EXCEPT ELECTRIC--> for schematic and connector information.

GO to A11
No : GO to A9

A5 CHECK THE PASSENGER SEATBELT SENSOR DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (OPEN INDICATED)

NOTE: This pinpoint test step attempts to change the fault reported by the RCM by inducing a different fault condition. If the reported fault changes, this indicates the RCM is functioning correctly and is not the source of the fault.

Ignition OFF.
Depower the SRS .
REFER to: SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
Disconnect Passenger Safety Belt Buckle Switch (Inline) C3007J .

Connect a fused jumper wire:

Positive Lead	Measurement/Action	Negative Lead
C3007J-1		C3007J-2

Repower the SRS . Do not prove out the SRS at this time.
REFER to: SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
Ignition ON.
Enter the following diagnostic mode: Self Test - RCM .
DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the passenger safety belt buckle switch circuits shorted together, a short to ground fault is normally retrieved. Due to the inline connector being disconnected, a fault is also normally retrieved for the OCS , passenger seat track position sensor and passenger side air bag circuits.

Did the on-demand DTC change from B0052:13 to B0052:11?

Yes : REMOVE the fused jumper wire and GO to A8
No : REMOVE the fused jumper wire and GO to A6

Measure:

Positive Lead	Measurement/Action	Negative Lead
C310B-25		C3007J-1

Is the resistance less than 0.5 ohm?

Yes : GO to A7
No : REPAIR the circuit.
Refer to OEM CONNECTOR REPAIR PROCEDURES EXCEPT ELECTRIC--> for schematic and connector information.
