Pinpoint Test A : B0028:11, B0028:12, B0028:13 And B0028:1A

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™ 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.
  1. A1 RETRIEVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS) 

    Was DTC B0028:11, B0028:12, B0028:13 or B0028:1A retrieved on-dem and during self-test? 

    1. Yes:  This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-dem and during self-test.

      For DTC B0028:13 or B0028:1A, GO to A2

      For DTC B0028:11, GO to  A8

      For DTC B0028:12, GO to  A10

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

      For DTC B0028:13 or B0028:1A, GO to  A13

      For DTC B0028:11, GO to  A14

      For DTC B0028:12, GO to  A15

  2. A2 CHECK THE RIGHT SIDE AIRBAG DEPLOYMENT CONTROL RESISTANCE (DEPLOY_13_R) PARAMETER IDENTIFICATION (PID) 
    • Using a diagnostic scan tool, view RCM Parameter Identifications (PIDs).
    • Monitor and record the resistance value displayed by the DEPLOY_13_R Parameter Identification (PID).

    Does the Parameter Identification (PID) value read between 1.7 and 2.78 ohms? 

    1. Yes:  GO to  A12
    2. No:  GO to A3
  3. A3 CHECK THE RIGHT SIDE AIRBAG DEPLOYMENT CONTROL RESISTANCE (DEPLOY_13_R) PARAMETER IDENTIFICATION (PID) WHILE CARRYING OUT THE HARNESS TEST 
    • While monitoring the DEPLOY_13_R Parameter Identification (PID), carry out the harness test of the passenger seat side airbag circuits and accessible connectors (including any inline connectors) by wiggling and flexing the wire harness and connectors frequently. Record the resistance value indicated by the Parameter Identification (PID).

    Does the Parameter Identification (PID) value read between 1.7 and 2.78 ohms while carrying out the harness test? 

    1. Yes:  DEPOWER the SRS and REPAIR the connector, terminals or wire harness as needed.

      Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

      GO to  A17

    2. No:  For Parameter Identification (PID) value less than 1.7 ohms, GO to A4

      For Parameter Identification (PID) value greater than 2.78 ohms, GO to  A6

  4. A4 CHECK THE RIGHT SIDE AIRBAG DEPLOYMENT CONTROL DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (LOW RESISTANCE 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 Seat Side Airbag (Inline) C3007B.

      REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .

    • Ignition ON.
    • Using a diagnostic scan tool, perform RCM self-test.
    • DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the passenger seat side airbag disconnected, an open circuit fault is normally retrieved. Due to the inline seat connector being disconnected, Diagnostic Trouble Codes (DTCs) will also set for the seat track position sensor, safety belt buckle switch and OCSM.

    Did the on-demand DTC change from B0028:1A to B0028:13? 

    1. Yes:  GO to  A11
