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.
NOTE: Do not probe any impact sensor. The impact sensor cannot be tested using a multi-meter
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 B1413:11 or B1413:93 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 also 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 impact sensor Diagnostic Trouble Codes (DTCs). For DTC B1413:11, GO to A2 For DTC B1413:93, GO to A5 |
|---|---|
No | If DTC U3003:16 or U3003:17 is also retrieved on-demand, 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 impact sensor Continuous Memory Diagnostic Trouble Codes (CMDTCs). This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to A10 |
A2 CHECK THE LEFT FRONTAL RESTRAINTS SENSOR DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (SHORT TO GROUND 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 LH Front Impact Severity Sensor C1465.
Remove the air cleaner. Refer to the appropriate section in Group 303 for the procedure.
Repower the SRS. Do not prove out the SRS at this time.
