bag connector(s).
WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
With the scan tool, read the active Occupant Restraint Controller
DTC’s.
Does the scan tool display DRIVER AIRBAG SQUIB 1 CIRCUIT
LOW?
Yes
>> Go to 3
No
>> Replace the Driver Airbag in accordance with Service
Information.
Perform ORC VERIFICATION TEST - VER 1
3.

spring harness connector(s).
WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
With the scan tool, read the active Occupant Restraint Controller
DTC’s.
Does the scan tool display DRIVER AIRBAG SQUIB 1 CIRCUIT
LOW?
Yes
>> Go to 4
No
>> Replace the Clockspring in accordance with the Service
Information.
