B1B05-DRIVER AIRBAG SQUIB 2 CIRCUIT HIGH





For a complete wiring diagram Refer to Section 8W.


  • When Monitored:

    With the ignition on.

  • Set Condition:

    The Occupant Restraint Controller (ORC) monitors the voltage on the Driver Squib 2 circuits. The ORC will set this DTC if it detects voltage on the Driver Squib 2 circuits.


Possible Causes
 
(R63) DRIVER SQUIB 2 LINE 1 CIRCUIT OR (R61) DRIVER SQUIB 2 LINE 2 CIRCUIT SHORTED TO BATTERY
 
STEERING CONTROL MODULE (SCM)
 
DRIVER AIRBAG
 
OCCUPANT RESTRAINT CONTROLLER (ORC)
 




Diagnostic Test

1.DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure that the battery is fully charged.

NOTE: The Scan Tool, SRS Airbag Load Tool MRL 8443 and DVOM are required to perform the following test.




Select ACTIVE or STORED DTC:

ACTIVE DTC
  • Go To 2


STORED DTC
  • Go To 5

2.CHECK FOR SHORTED SQUIB CIRCUITS IN DRIVER AIRBAG


WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.



WARNING: To avoid personal injury or death, do not place an intact undeployed airbag face down on a hard surface, the airbag will propel into the air if accidentally deployed.


NOTE: Check connectors - Clean and repair as necessary.



WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.




Does the scan tool display: B1B05-DRIVER AIRBAG SQUIB 2 CIRCUIT HIGH?

Yes
  • Go To 3


No
  • Replace the Driver Airbag in accordance with the Service Information.
  • Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

3.CHECK STEERING CONTROL MODULE (CLOCKSPRING) SQUIB CIRCUITS FOR A SHORT TO BATTERY


WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.




NOTE: Check connectors - Clean and repair as necessary.



WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.




Does the scan tool display: B1B05-DRIVER AIRBAG SQUIB 2 CIRCUIT HIGH?

Yes
  • Go To 4


No
  • Replace the Steering Control Module in accordance with the Service Information.
  • Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

4.CHECK (R63) DRIVER SQUIB 2 LINE 1 CIRCUIT AND (R61) DRIVER SQUIB 2 LINE 2 CIRCUIT FOR A SHORT TO BATTERY


WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.




NOTE: Check connectors - Clean and repair as necessary.



NOTE: The IP Harness is always connected to the right side (C1) of the 8443-32-L Adapter.


WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.





Is there any voltage present for either measurement?

Yes
  • Repair the Driver Squib 2 circuits with voltage present for a short to battery.
  • Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.


No
  • WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and personal injury or death.

    WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

  • Replace the ORC in accordance with Service Information.
  • Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

5.CHECKING STORED OR INTERMITTENT CODES

NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to the Table of Contents in this Section for a complete list of airbag system diagnostic procedures.



WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.




WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.


  • Wiggle the wiring harness and connectors of the related airbag circuit.
  • Continue the test until either a code becomes active or the problem area is isolated.



Are any ACTIVE DTCs present?

Yes
  • Select the appropriate diagnostic procedure from the Table of Contents in this section.


No
  • No problem found at this time. Erase all codes before returning the vehicle to the customer.
