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 B0001:11, B0001:12, B0001:13 or B0001:1A 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 driver airbag Diagnostic Trouble Codes (DTCs). For DTC B0001:13 or B0001:1A, GO to A2 For DTC B0001:11, GO to A12 For DTC B0001:12, GO to A15 |
|---|---|
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 driver airbag Continuous Memory Diagnostic Trouble Codes (CMDTCs). For DTC B0001:13 or B0001:1A, GO to A20 For DTC B0001:11, GO to A21 For DTC B0001:12, GO to A22 |
A2 CHECK THE DRIVER FRONTAL STAGE 1 DEPLOYMENT CONTROL RESISTANCE (DEPLOY_00_R) PID (PARAMETER IDENTIFICATION)
Using a diagnostic scan tool, view RCM Parameter Identifications (PIDs). Monitor and record the resistance value displayed by the DEPLOY_00_R PID.
Does the PID value read between 1.62 and 4.46 ohms?
Yes | GO to A19 |
|---|---|
No | GO to A3 |
A3 CHECK THE DRIVER FRONTAL STAGE 1 DEPLOYMENT CONTROL RESISTANCE (DEPLOY_00_R) PID (PARAMETER IDENTIFICATION) WHILE CARRYING OUT THE HARNESS TEST
Remove the steering column shrouds to access the clockspring connectors. REFER to: Steering Column Shrouds (501-05 Interior Trim and Ornamentation, Removal and Installation). While monitoring the DEPLOY_00_R PID, carry out the harness test of the driver airbag circuits and accessible connectors (including any inline connectors) by wiggling and flexing the wire harness, connectors, tilting and rotating the steering wheel frequently. Record the resistance value indicated by the PID.
Does the PID value read between 1.62 and 4.46 ohms while carrying out the harness test?
Yes | DEPOWER the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). REPAIR the connector, terminals or wire harness or INSTALL a new clockspring as needed. REFER to: Clockspring (501-20B Supplemental Restraint System, Removal and Installation). Refer to Wiring Diagrams Cell 5 for schematic and connector information. GO to A24 |
|---|---|
No | For PID value less than 1.62 ohms, GO to A4 For PID value greater than 4.46 ohms, GO to A8 |
A4 CHECK THE DRIVER 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). Remove the driver airbag. REFER to: Driver Airbag (501-20B Supplemental Restraint System, Removal and Installation). 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 driver airbag disconnected, open circuit faults are normally retrieved on stages 1 and 2.
Did the on-demand DTC change from B0001:1A to B0001:13?
