When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the resistance of the Driver Squib 2
circuits.
•
Set Condition:
The ORC has detected low resistance between the Driver Squib 2 circuits.

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.
Disconnect the Driver Airbag Squib connectors.
NOTE: Check connectors - Clean and repair as necessary.
Connect the 8443 Load Tool and appropriate Jumper to the Driver Air-
bag Squib connectors.
WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
With the scan tool, read the active ORC DTC’s.
Does the scan tool display: B1B07 DRIVER AIRBAG SQUIB 2
CIRCUIT SHORTED TOGETHER?
Yes
>> Go To 3
No
>> Replace the Driver Airbag in accordance with the Service
Information.
Perform ORC VERIFICATION TEST - VER 1. (Refer to 8 -
ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TEST-
ING)
3.
CHECK CLOCKSPRING SQUIB CIRCUITS FOR A SHORT
TOGETHER
WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Disconnect the 8443 Load Tool ORC from the Driver Airbag Squib
connectors.
Disconnect the Steering Control Module C2 connector.
NOTE: Check connectors - Clean and repair as necessary.
Connect the 8443 Load Tool and appropriate Jumper to the Steering
Control Module connector.
WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
With the scan tool, read the active ORC DTC’s.
Does the scan tool display: B1B07 DRIVER AIRBAG SQUIB 2
CIRCUIT SHORTED TOGETHER?
Yes
>> Go To 4
No
>> Replace the Steering Control Module in accordance with
the Service Information.
Perform ORC VERIFICATION TEST - VER 1. (Refer to 8 -

CHECK (R63) DRIVER SQUIB 2 LINE 1 CIRCUIT FOR A SHORT TO (R61) DRIVER SQUIB 2 LINE 2
CIRCUIT
WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Disconnect the 8443 Load Tool and Jumper from the Steering Control
Module connector.
Disconnect the ORC connectors.
NOTE: Check connectors - Clean and repair as necessary.
Connect the 8443 Load Tool ORC Adaptor to the ORC C2 connector.
Measure the resistance between the (R63) Driver Squib 2 Line 1 cir-
cuit and the (R61) Driver Squib 2 Line 2 circuit at the adaptor.
Is the resistance below 10K ohms?
Yes
>> Repair the (R63) Driver Squib 2 Line 1 circuit for a short to
the (R61) Driver Squib 2 Line 2 circuit.
Perform ORC VERIFICATION TEST - VER 1. (Refer to 8 -
ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TEST-
ING)
No
>> Go To 5
5.
REPLACE THE ORC
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.
NOTE: When reconnecting airbag system components the Ignition must be turned off and the Battery must
be disconnected.
Repair
Replace the ORC in accordance with the Service Information.
