B1B09 Passanger Airbag Squib 1 Circuit High

B1B09 Code - The Occupant Restraint Controller (ORC) monitors the voltage on the Passanger Squib 1 circuits. The ORC will set this DTC if it detects voltage on the Passanger Squib 1 circuits.

B1B09


Possible causes B1B09 Code

  • Passanger Squib 1 line 2 circuit shorted to Battery
  • Passanger Squib 1 line 1 circuit shorted to Battery
  • Passanger Airbag
  • Occupant Restraint Controller (ORC) Module

Diagnostic test B1B09 code

Step 1. Determine active that the Battery is fully charged
Make sure that the Battery is fully charged. The scan tool, SRS load tool kit and DVOM are required to perform the follwoing test.
Turn the ignition on, with the scan tool read the active ORC DTCs.

Select active or stored DTC:

Active DTC, go to step 2.
Stored DTC, go to step 4.

Step 2. Check for shorted Squib circuits in Passanger Airbag

B1B09


Turn the ignition off, disconnect the 12Volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
Disconnect the Passanger Airbag Squib connectors. 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.
Check connectors-clean and repair as necessary. Connect the SRS load tool and SRS load tool jumper to passanger airbag squib connectors.
Turn the ignition on, then reconnect the 12Volt battery and wait two minutes before proceeding. Failure to follow these instuctions may result in possible serious or fatal injury. With the scan tool, read the active ORC DTCs.

Does the scan tool display: B1B09 Code?

Yes, go to step 3.
No, 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 Passanger Airbag, perform the Airbag system verification.

Step 3. Check Passanger Squib 1 line 2 circuit and Passanger Squib 1 line 1

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.
Disconnect the SRS load tool kit and SRS load tool jumper from the Passanger Airbag Squib connectors, disconnect the ORC connectors. Check connectors-clean and repair as necessary. Connect the SRS load tool adaftor to the ORC connectors.
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.
Measure the voltage of the Passanger Squib 1 line 2 circuit between the SRS load tool adaptor. Measure the voltage of the Passanger Squib 1 line 1 circuit between the SRS load tool adaptor.

Is there any voltage present on either circuit?

Yes, 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. Repair the Passanger Squib 1 circuits with voltage present for short to battery.
No, 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. 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, perform the Airbag system verification.

Step 4. Checking stored or intermittent codes

Diagnose and repair all active codes before diagnosing stored codes. With the sacn tool, record and erase all Airbag System Module DTCs. 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. 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. Reapir as necessary. Reconnect all disconnected components and harness connectors.
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.

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.
In the previous steps you have attempted to recreate the responsible for setting the DTC in question/causing the intermittent condition.

Are any active DTCs present?

Yes, repair and peform the appropriate diagnostics.
No, no problem found at this time. Erase all codes before returning the vehicle to the customer.
