A7 CHECK THE PASSENGER AIRBAG ADAPTIVE CANISTER VENT DEPLOYMENT CONTROL 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.
Connect RCM C310A and C310B. Connect a fused jumper wire:
Click to display connectors
Lead 1 | Measurement / Action | Lead 2 |
|---|---|---|
C256-7 | C256-8 |
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 adaptive canister vent circuits shorted together, a low resistance fault is normally retrieved. An open circuit fault is also retrieved on passenger airbag stages 1 and 2, due to the passenger airbag connector being disconnected.
Did the on-demand DTC change from B11CF:13 to B11CF:1A?

No | REMOVE the fused jumper wire and GO to A12 |
A8 CHECK THE PASSENGER AIRBAG ADAPTIVE CANISTER VENT DEPLOYMENT CONTROL 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). Remove the glove compartment. REFER to: Glove Compartment (501-12 Instrument Panel and Console, Removal and Installation). 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 adaptive canister vent disconnected, an open circuit fault is normally retrieved. An open circuit fault is also retrieved on passenger airbag stages 1 and 2, due to the passenger airbag connector being disconnected.
