For a complete wiring diagram, refer to the Wiring Information.
Theory of Operation
When Monitored:
With the
ignition on.
Set Condition:
The Occupant
Restraint Controller (ORC) monitors the resistance of the Passenger
Squib 2 circuits. The ORC will set this DTC if it detects an open
or high resistance on the Passenger Squib 2 circuits.
Possible Causes
(R64) PASSENGER SQUIB
2 LINE 1 CIRCUIT OPEN
(R62) PASSENGER SQUIB
2 LINE 2 CIRCUIT OPEN
PASSENGER AIRBAG
OCCUPANT RESTRAINT
CONTROLLER (ORC)
1.
DETERMINE ACTIVE OR STORED DTC
NOTE:
Make sure that the battery is fully charged.
NOTE:
The scan tool, SRS Load Tool Kit 8443A, and DVOM are required to perform the following test.
2.
CHECK FOR OPEN SQUIB CIRCUITS IN PASSENGER AIRBAG
WARNING:
Turn the ignition off, disconnect
the 12-volt battery and wait two minutes before proceeding. Failure
to follow these instructions may result in possible serious or fatal
injury.
1.
Disconnect the Passenger Airbag Squib connectors.
WARNING:
Do not place an intact non-deployed
airbag face down on a hard surface, the airbag propels into the air
if accidentally deployed. Failure to follow these instructions may
result in possible serious or fatal injury.
NOTE:
Check connectors - Clean and repair as necessary.
2.
Connect the SRS Load Tool Kit
8443A
and SRS Load Tool Jumper
8443-8
to the Passenger Airbag Squib connectors.
WARNING:
Turn the ignition on, then reconnect
the 12-volt battery and wait two minutes before proceeding. Failure
to follow these instructions may result in possible serious or fatal
injury.
3.
With the scan tool, read the active ORC DTCs.
Does the scan tool display B1B0E-PASSENGER AIRBAG SQUIB 2 CIRCUIT OPEN DTC?
Turn the ignition off, disconnect
the 12-volt battery and wait two minutes before proceeding. Failure
to follow these instructions may result in possible serious or fatal
injury.
Replace the Passenger Airbag in accordance with the Service Information.
3.
CHECK (R64) PASSENGER SQUIB 2 LINE 1 CIRCUIT FOR AN OPEN
WARNING:
Turn the ignition off, disconnect
the 12-volt battery and wait two minutes before proceeding. Failure
to follow these instructions may result in possible serious or fatal
injury.
1.
Disconnect the SRS Load Tool Kit
8443A
and SRS Load Tool Jumper
8443-8
from the Passenger Airbag Squib connectors.
2.
Disconnect the ORC connectors.
NOTE:
Check connectors - Clean and repair as necessary.
3.
Connect the SRS Load Tool Adaptor
8443-32-L
to the ORC connectors.
NOTE:
The IP Harness is always connected to the right side (C1) of the Adapter 8443-32-L.
4.
Measure the resistance of the (R64) Passenger Squib 2 Line 1 circuit between the Passenger Airbag Squib connector cavity 2 and the SRS Load Tool Adaptor
8443-32-L
cavity C1-4.
4.
CHECK (R62) PASSENGER SQUIB 2 LINE 2 CIRCUIT FOR AN OPEN
1.
Measure the resistance of the (R62) Passenger Squib 2 Line 2 circuit between the Passenger Airbag Squib connector cavity 1 and the SRS Load Tool Adaptor
8443-32-L
cavity C1-3.
Is the resistance below 1.0 Ohm?
Yes
WARNING:
If the Occupant Restraint Controller
(ORC) is dropped at any time, it must be replaced. Failure to follow
these instructions may result in possible serious or fatal injury.
Replace the Occupant Restraint Controller in accordance with the Service Information.
With the scan tool, record and erase all Airbag System Module DTCs.
WARNING:
Turn the ignition off, disconnect
the 12-volt battery and wait two minutes before proceeding. Failure
to follow these instructions may result in possible serious or fatal
injury.
2.
Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chafed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.
3.
Reconnect all disconnected components and harness connectors.
WARNING:
Turn the ignition on, then reconnect
the 12-volt battery and wait two minutes before proceeding. Failure
to follow these instructions may result in possible serious or fatal
injury.
4.
With the scan tool, monitor for active codes while performing the following:
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.
5.
In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question / causing the intermittent condition.
