Theory of Operation


Possible Causes

(R42) PASSENGER SQUIB 1 LINE 2 CIRCUIT SHORTED TO THE (R44) PASSENGER SQUIB 1 LINE 1 CIRCUIT
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.
1. Turn the ignition on.
2. With the scan tool, read the active ORC DTCs.


Select ACTIVE or STORED DTC:

ACTIVE DTC


STORED DTC


2. CHECK FOR SHORTED 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.


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: B1B0B-PASSENGER AIRBAG SQUIB 1 CIRCUIT SHORTED TOGETHER?

Yes


No


3. CHECK (R42) PASSENGER SQUIB 1 LINE 2 CIRCUIT FOR A SHORT TO (R44) PASSENGER SQUIB 1 LINE 1 CIRCUIT

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 between the (R42) Passenger Squib 1 Line 2 circuit cavity C1-2 and the (R44) Passenger Squib 1 Line 1 circuit cavity C1-1 at the SRS Load Tool Adaptor 8443-32-L .


Is the resistance below 10K Ohms?

Yes


No


4. CHECKING STORED OR INTERMITTENT CODES



NOTE: Diagnose and repair all active codes before diagnosing stored codes. (Refer to 28 - DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Diagnosis and Testing) for a complete list of airbag system diagnostic procedures.
1. 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.


Are any ACTIVE DTCs present?

Yes


No
