Chrysler 300/300 Touring/300C, Dodge Magnum. Manual - part 675

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

STORED ORC DTC

With the scan tool, record and erase all DTC’s from all Airbag System Modules.

If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

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 wiring and connectors.

Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or con-
taminated terminals.

The following additional checks may assist you in identifying a possible intermittent problem.

Reconnect any disconnected components and harness connector.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.
With the scan tool monitor active codes as you work through the following steps.

Wiggle the wiring harness and connectors of the related airbag circuit or component.

If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.

If only stored codes return continue the test until the problem area has been isolated.

In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

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 vehicle to customer.

When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the resistance of the Right Curtain
Squib 1 circuits.

•

Set Condition:
The ORC has detected low resistance between the Right Curtain Squib 1 circuits.

Diagnostic Test

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.
Select Active or Stored DTC.

CHECK FOR SHORTED SQUIB CIRCUITS IN RIGHT SIDE CURTAIN AIRBAG

WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Disconnect the Right Side Curtain Airbag connector.

WARNING: To avoid personal injury or death, do not place an
intact uncoupled curtain 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.
Connect the 8443 Load Tool and appropriate Jumper to the Right Side
Curtain Airbag connector.

WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
With the scan tool, read the active ORC DTC’s.

Does the scan tool display: B1B23 RIGHT SIDE CURTAIN
SQUIB 1 CIRCUIT SHORTED TOGETHER?

Yes

>> Go to 3

>> Replace the Right Side Curtain Airbag in accordance with

the Service Information.

CHECK (R4) RIGHT CURTAIN SQUIB 1 LINE 1 CIRCUIT FOR A SHORT TO (R2) RIGHT CURTAIN SQUIB 1
LINE 2 CIRCUIT

WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Disconnect the 8443 Load Tool and Jumper from the Right Side Curtain
Airbag connector.

Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.
Connect the 8443 Load Tool ORC Adaptor to the ORC C1 connector.

Measure the resistance between the (R4) Right Curtain Squib 1 Line 1
circuit and the (R2) Right Curtain Squib 1 Line 2 circuit at the Right
Side Curtain Airbag connector.

Is the resistance below 10K ohms?

Yes

>> Repair the (R4) Right Curtain Squib 1 Line 1 circuit for a

short to the (R2) Right Curtain Squib 1 Line 2 circuit.
