B1B00-DRIVER AIRBAG SQUIB 1 CIRCUIT LOW

For a complete wiring diagram Refer to Section 8W.

When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the resistance of the Driver Squib 1 circuits.
Set Condition:
The ORC has detected low resistance on the Driver Squib 1 circuits.

Possible Causes

(R43) DRIVER SQUIB 1 LINE 2 CIRCUIT OR (R45) DRIVER SQUIB 1 LINE 1 CIRCUIT SHORTED TO GROUND

STEERING CONTROL MODULE

DRIVER AIRBAG

ORC

Diagnostic Test

1.DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure the battery is fully charged.

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

NOTE: When reconnecting airbag system components the Ignition must be turned off and the Battery must be disconnected.

Is the DTC active or stored?

ORC - ACTIVE DTC

Go To 2

ORC - STORED DTC

Go To 6

2.CHECK FOR SHORTED SQUIB CIRCUITS IN DRIVER AIRBAG

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

WARNING: To avoid personal injury or death, 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.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

Does the scan tool display: B1B00-DRIVER AIRBAG SQUIB 1 CIRCUIT LOW?

Yes

Go To 3

Replace the Driver Airbag in accordance with the Service Information.
Perform *ORC VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TESTING)

3.CHECK CLOCKSPRING SQUIB CIRCUITS FOR A SHORT TO GROUND

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

NOTE: Check connectors - Clean and repair as necessary.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

Does the scan tool display: B1B00-DRIVER AIRBAG SQUIB 1 CIRCUIT LOW?

Yes

Go To 4

Replace the Steering Column Control Module in accordance with the Service Information.
Perform *ORC VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TESTING)

4.CHECK (R43) DRIVER SQUIB 1 LINE 2 CIRCUIT AND (R45) DRIVER SQUIB 1 LINE 1 CIRCUIT FOR A SHORT TO GROUND

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

NOTE: Check connectors - Clean and repair as necessary.

Is the resistance below 10K ohms for either measurement?

Yes

Repair the Driver Squib 1 circuit(s) for a short to ground.
Perform *ORC VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TESTING)

Go To 5

5.REPLACE THE ORC

WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and personal injury or death.

NOTE: When reconnecting airbag system components the Ignition must be turned off and the Battery must be disconnected.

Repair

Replace the ORC in accordance with the Service Information.
Perform *ORC VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TESTING)

6.STORED ORC DTC

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

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

Are any ACTIVE DTCs present?
