B1B0C-PASSENGER AIRBAG SQUIB 2 CIRCUIT LOW





For a complete wiring diagram Refer to Section 8W.



Possible Causes
(R64) PASSENGER SQUIB 2 LINE 1 CIRCUIT SHORTED TO GROUND
(R62) PASSENGER SQUIB 2 LINE 2 CIRCUIT SHORTED TO GROUND
PASSENGER AIRBAG
OCCUPANT RESTRAINT CONTROLLER (ORC)



Diagnostic Test

1. DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure that the battery is fully charged.

NOTE: The scan tool, SRS Airbag Load Tool MRL 8443, and DVOM are required to perform the following test.


Turn the ignition on.

Select ACTIVE or STORED DTC:

ACTIVE DTC


STORED DTC

2. CHECK FOR SHORTED SQUIB CIRCUITS IN PASSENGER AIRBAG


WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.


Disconnect the Passenger Airbag Squib connectors.

WARNING: To avoid serious or fatal injury, do not place an intact undeployed 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 8443-8 Jumper to the Passenger Airbag Squib connectors.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.


With the scan tool, read the active ORC DTC.

Does the scan tool display: B1B0C-PASSENGER AIRBAG SQUIB 2 CIRCUIT LOW?

Yes


No

3. CHECK (R64) PASSENGER SQUIB 2 LINE 1 CIRCUIT AND (R62) PASSENGER SQUIB 2 LINE 2 CIRCUIT FOR A SHORT TO GROUND


WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.


Disconnect the 8443 Load Tool and Jumper from the Passenger Airbag Squib connectors.
Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.


Connect the 8443-32-L ORC Adaptor to the ORC connectors.
Measure the resistance of the (R64) Passenger Squib 2 Line 1 circuit between ORC 8443-32-L Adaptor cavity C1-15 and ground.
Measure the resistance of the (R62) Passenger Squib 2 Line 2 circuit between ORC 8443-32-L Adaptor cavity C1-16 and ground.

Is the resistance below 10k ohms on either circuit?

Yes


No

4. CHECKING STORED OR INTERMITTENT CODES

NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to the Table of Contents in this Section for a complete list of airbag system diagnostic procedures.


With the scan tool, record and erase all Airbag System Module DTC.

WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.


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.
Reconnect all disconnected components and harness connectors.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.


With the scan tool, monitor for active codes while performing the following:
In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question / causing the intermittent condition.

Are any ACTIVE DTC present?

Yes


No
