RIGHT SIDE CURTAIN AIRBAG SHORTED
WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Disconnect the Right Side Curtain Airbag connector(s).
WARNING: To avoid personal injury or death, do not place an
intact uncoupled curtain 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.
Connect the 8443 Load Tool and appropriate Jumper to the Right Side
Curtain Airbag 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 RIGHT SIDE CURTAIN SQUIB 1 CIR-
CUIT SHORT TOGETHER?
Yes
>> Go to 3
No
>> Replace the Right Side Curtain Airbag in accordance with
Service Information.
Perform AIRBAG VERIFICATION TEST - VER 1
3.
(R4) RIGHT CURTAIN SQUIB 1 LINE 1 SHORTED TO (R2) RIGHT CURTAIN SQUIB 1 LINE 2
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 Right Side Cur-
tain Airbag connector(s).
Disconnect the ORC harness connector(s).
NOTE: Check connectors - Clean and repair as necessary.
Connect the 8443 Load Tool ORC Adaptor to the ORC harness con-
nector.
Measure the resistance between the (R4) Right Curtain Squib 1 Line 1
and (R2) Right Curtain Squib 1 Line 2 at the Right Side Curtain Airbag
harness connector.
Is the resistance below 10K ohms?
Yes
>> Repair the (R4) Right Curtain Squib 1 Line 1 shorted to the (R2) Right Curtain Squib 1 Line 2 circuit.
Perform AIRBAG VERIFICATION TEST - VER 1
No

OCCUPANT RESTRAINT CONTROLLER
WARNING: If the Airbag Control Module 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.
Disconnect the 8443 Load Tool ORC Adaptor from the ORC harness connector.
NOTE: When reconnecting airbag system components the Ignition must be turned off and the Battery must
be disconnected.
If there are no possible causes remaining, view repair.
Repair
Replace the Occupant Restraint Controller in accordance with Service Information.
Perform AIRBAG VERIFICATION TEST - VER 1
5.
STORED ORC DTC
With the scan tool, record and erase all DTC’s from all Airbag System
Modules.
If any ACTIVE codes are present they must be resolved before diag-
nosing any stored codes.
WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Using the wiring diagram/schematic as a guide, inspect the wiring and
connectors.
Look for chaffed, pierced, pinched, or partially broken wires and bro-
ken, bent, pushed out, spread, corroded, or contaminated terminals.
The following additional checks may assist you in identifying a possi-
ble intermittent problem.
Reconnect any disconnected components and harness connector.
WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
With the scan tool monitor active codes as you work through the fol-
lowing steps.
Wiggle the wiring harness and connectors of the related airbag circuit or component.
If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
IF only stored codes return continue the test until the problem area has been isolated.
In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.
Are any ACTIVE DTC’s present?
Yes
>> Select appropriate symptom from Symptom List.
No
>> No problem found at this time. Erase all codes before returning vehicle to customer.
