CHECK FOR OPEN SQUIB CIRCUITS IN PASSENGER AIRBAG
WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Disconnect the Passenger Airbag Squib connector.
WARNING: To avoid personal injury or death, do not place an
intact undeployed airbag face down on a hard surface, the airbag

With the scan tool, read the active ORC DTC’s.
Does the scan tool display: B1B0E PASSENGER AIRBAG
SQUIB CIRCUIT OPEN?
Yes
>> Go To 3
No
>> Replace the Passenger Airbag in accordance with the Ser-
vice Information.
Perform ORC VERIFICATION TEST - VER 1. (Refer to 8 -
ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TEST-

Measure the resistance of the (R64) Passenger Squib 2 Line 1 circuit
between the Passenger Airbag Squib connector and the 8443 Load
Tool ORC Adaptor.
Is the resistance below 1.0 ohm?
Yes
>> Go to 4
No
>> Repair the (R64) Passenger Squib 2 Line 1 circuit for an

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 diagnosing any stored codes.
WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two min-
utes 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 broken, bent, pushed out, spread, corroded, or
contaminated terminals.
The following additional checks may assist you in identifying a possible 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 following steps.
Wiggle the wiring harness and connectors of the related airbag circuit or component.
If codes are related to the Passenger 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 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 vehicle to customer.
