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.
A1 RETRIEVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
WARNING: Before beginning any service procedure in this section, refer to Safety Warnings in section 100-00 General Information. Failure to follow this instruction may result in serious personal injury.
REFER to: Pyrotechnic Device Health and Safety Precautions (100-00 General Information, Description and Operation). Ignition ON. Using a diagnostic scan tool, perform RCM self-test.
Was DTC B0010:11, B0010:12, B0010:13 or B0010:1A 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. If DTC U3003:16 or U3003:17 is retrieved on-demand, DIAGNOSE those Diagnostic Trouble Codes (DTCs) first. REFER to: Pinpoint Test - DTC: AJ (501-20B Supplemental Restraint System, Diagnosis and Testing). If DTC U3003:16 or U3003:17 is not retrieved on-demand during self-test, DIAGNOSE the passenger airbag Diagnostic Trouble Codes (DTCs). For DTC B0010:13 or B0010:1A, GO to A2 For DTC B0010:11, GO to A9 For DTC B0010:12, GO to A11 |
|---|---|
No | This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. If DTC U3003:16 or U3003:17 is retrieved on-demand, DIAGNOSE those Diagnostic Trouble Codes (DTCs) first. REFER to: Pinpoint Test - DTC: AJ (501-20B Supplemental Restraint System, Diagnosis and Testing). If DTC U3003:16 or U3003:17 is not retrieved on-demand during self-test, DIAGNOSE the passenger airbag Continuous Memory Diagnostic Trouble Codes (CMDTCs). For DTC B0010:13 or B0010:1A, GO to A14 For DTC B0010:11, GO to A15 For DTC B0010:12, GO to A16 |
A2 CHECK THE PASSENGER FRONTAL STAGE 1 DEPLOYMENT CONTROL RESISTANCE (DEPLOY_05_R) PID (PARAMETER IDENTIFICATION)
Using a diagnostic scan tool, view RCM Parameter Identifications (PIDs). Monitor and record the resistance value displayed by the DEPLOY_05_R PID.
Does the PID value read between 1.44 and 3.52 ohms?
Yes | GO to A13 |
|---|---|
No | GO to A3 |
A3 CHECK THE PASSENGER FRONTAL STAGE 1 DEPLOYMENT CONTROL RESISTANCE (DEPLOY_05_R) PID (PARAMETER IDENTIFICATION) WHILE CARRYING OUT THE HARNESS TEST
Remove the glove compartment. REFER to: Glove Compartment (501-12 Instrument Panel and Console, Removal and Installation). While monitoring the DEPLOY_05_R PID, carry out the harness test of the passenger 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 PID.
Does the PID value read between 1.44 and 3.52 ohms while carrying out the harness test?
Yes | DEPOWER the SRS and REPAIR the connector, terminals or wire harness. Refer to Wiring Diagrams Cell 5 for schematic and connector information. GO to A18 |
|---|---|
No | For PID value less than 1.44 ohms, GO to A4 For PID value greater than 3.52 ohms, GO to A7 |
A4 CHECK THE PASSENGER FRONTAL STAGE 1 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 (501-20B Supplemental Restraint System, General Procedures). Disconnect Passenger Airbag C256. Repower the SRS. Do not prove out the SRS at this time. REFER to: Supplemental Restraint System (SRS) Repowering (501-20B Supplemental Restraint System, General Procedures). Ignition ON. Using a diagnostic scan tool, perform RCM self-test. DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the passenger airbag disconnected, open circuit faults are normally retrieved on passenger airbag stages 1 and 2, and for the passenger airbag canister vent.
Did the on-demand DTC change from B0010:1A to B0010:13?
