B0010-13-PASSENGER FRONTAL SQUIB 1 CONTROL - CIRCUIT OPEN

Special Tools:










For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation
When powered, the Occupant Restraint Controller (ORC) sends a test current to the squibs to verify the integrity of the squib and wiring. These circuits are maintained in a "floating" configuration at the ORC (connected to neither power nor ground) as protection against inadvertent deployment. Use of the Supplemental Restraints System (SRS) load Tool Kit in the tests below substitutes a suspect squib with a known good component. The use of the SRS Load Tool Adapter provides a test point as well as a method for opening the shorting bar connections within the ORC harness connector.
- When Monitored:
The ORC sends out a 40 mA diagnostic current on each squib voltage supply circuit at power up and every 100 ms thereafter while the ignition is on.

- Set Condition:
This Diagnostic Trouble Code (DTC) sets when the ORC detects an open or high resistance on the squib circuit for more than 2.5 seconds. This DTC transitions from active to stored when the ORC sees a recovery from an open condition for greater than 2.5 seconds.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.

1. VERIFY ACTIVE DTC

NOTE: Make sure the battery is fully charged.

1. Turn the ignition on.
2. With the scan tool, read ORC DTCs

Does the scan tool display active B0010-13-PASSENGER FRONTAL SQUIB 1 CONTROL - CIRCUIT OPEN DTC?

Yes

- Go To 2

No

- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test

2. CHECK FOR OPEN PASSENGER AIRBAG SQUIB CIRCUITS





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 harness 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 and SRS Load Tool Jumper to the Passenger Airbag Squib 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.

3. With the scan tool, read the ORC DTCs.

Does the scan tool display active B0010-13-PASSENGER FRONTAL SQUIB 1 CONTROL - CIRCUIT OPEN DTC?

Yes

- Go To 3

No

- 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.

- Replace the Passenger Airbag.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

3. CHECK (R42, R64) PASSENGER SQUIB 1 CIRCUITS 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 and Jumper from the Passenger Airbag Squib harness connectors.
2. Disconnect the ORC harness connectors.

NOTE: Check connectors - Clean and repair as necessary.

3. Connect the SRS Load Tool Adapter to the ORC C2 harness connector.
4. Measure the resistance of the (R42) Passenger Squib 1 Line 2 circuit cavity 1 between the Passenger Airbag Squib 1 harness connector and the SRS Load Tool Adapter cavity 26.
5. Measure the resistance of the (R44) Passenger Squib 1 Line 1 circuit cavity 2 between the Passenger Airbag Squib 1 harness connector and the SRS Load Tool Adapter cavity 25.

Is the resistance below 1.0 Ohms on both circuits?

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 ORC.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- Repair the (R42, R44) Passenger Squib 1 circuits for an open or high resistance.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.
