The Occupant Restraint Controller (ORC) monitors the resistance of the Driver Knee Bolster Airbag circuits.
The ORC will set this DTC if it detects low resistance between the Driver Knee Bolster Airbag circuits.

Possible Causes

(R11) DRIVER KNEE BLOCKER SQUIB LINE 1 CIRCUIT SHORTED TO (R9) DRIVER KNEE BLOCKER SQUIB
LINE 2 CIRCUIT

DRIVER KNEE BOLSTER AIRBAG

OCCUPANT RESTRAINT CONTROLLER (ORC)

Diagnostic Test

DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure that the battery is fully charged.

BLOCKER SQUIB LINE 2 CIRCUIT

Disconnect the 8443 Load Tool from the Driver Knee Bolster Airbag
connector.

Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.
Connect the 8443 Load Tool ORC Adaptor to the ORC C2 connector.

Measure the resistance between the (R11) Driver Knee Blocker Squib
Line 1 circuit and the (R9) Driver Knee Blocker Squib Line 2 circuit at
the ORC adaptor.

Is the resistance below 10k ohms?

Yes

>> Repair the (R11) Driver Knee Blocker Squib Line 1 circuit

for a short to the (R9) Driver Knee Blocker Squib Line 2 cir-
cuit.

Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

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.

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

Replace the ORC in accordance with Service Information.

Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

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 DTCs.

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two min-
utes 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 personal injury or death, turn the ignition on, then reconnect the battery.
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 conditions responsible for setting the DTC in question/
causing the intermittent condition.

Are any ACTIVE DTCs present?

Yes

>> Select the appropriate diagnostic procedure from the Table of Contents in this section.

>> No problem found at this time. Erase all codes before returning the vehicle to the customer.
