Dodge Caliber. Manual - part 425

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.

•

When Monitored:
With the ignition on.

•

Set Condition:
The Occupant Restraint Controller (ORC) monitors the resistance of the Right Curtain Squib 1 circuits. The
ORC will set this DTC if it detects low resistance between the Right Curtain Squib 1 circuits.

Possible Causes

(R4) RIGHT CURTAIN SQUIB 1 LINE 1 CIRCUIT SHORTED TO (R2) RIGHT CURTAIN SQUIB 1 LINE 2
CIRCUIT

RIGHT SIDE CURTAIN AIRBAG

OCCUPANT RESTRAINT CONTROLLER (ORC)

Diagnostic Test

DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure that the battery is fully charged.

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

Select ACTIVE or STORED DTC:

ACTIVE 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 8443-8 Jumper to the Right Side Cur-
tain 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 DTCs.

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.

Perform AIRBAG SYSTEM VERIFICATION TEST - VER 1.

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 8443-25 Adaptor to the ORC con-
nectors.

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 ORC
8443-25 Adaptor cavity 32-7 and 32-8.

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.

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.
