Dodge Caliber. Manual - part 465

INSPECT PASSENGER SEAT HARNESS WIRES AND CONNECTORS

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 Passenger Seat Harness wiring and connectors. Look
for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contam-
inated terminals.

Are any of these conditions present?

Yes

NOTE: Do not attempt to repair the Seat Harness. Replace the Seat Harness if the condition inspecting or
testing for is present in the Seat Harness.

Replace the Passenger Seat Harness in accordance with the Service Information.

Perform *OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST.

>> Go To 5

PERFORM OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST

Verify that all of the Seat Weight Sensor mounting screws are tightened to torque specification. Refer to Group 23
for specification.

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

NOTE: Failure to follow the test instructions or aborting the test will cause faults to set when performing
the Occupant Classification Module System Verification Test. To prevent faults due to process errors: verify
that all tests steps that led you here were performed as directed; verify that the ignition is in run; Wait 30
seconds after changing the seat weight before proceeding to allow the system to stabilize; only press scan
tool buttons when directed to do so; and perform the Occupant Classification Module System Verification
Test to completion.
With the scan tool in OCM, select More Options, select System Tests, and select Occupant Classification Module
System Verification Test. Run the test by following the instructions displayed on the scan tool. When the test is
complete, wait two minutes, and then proceed as follows.

With the scan tool, read OCM DTCs.

Does the scan tool display any active PASSENGER SEAT WEIGHT SENSOR PERFORMANCE DTCs?

Yes

>> Perform the *Diagnosis/Checkout Procedure For Seat Weight Sensors.

Perform *OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST.

Yes

>> Other DTCs ACTIVE? Diagnose and repair the DTCs. Refer to the Table of Contents in this Section for

a complete list of symptoms.

>> Perform *OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST.

TEST FOR INTERMITTENT CONDITION

With the scan tool, record and erase all DTCs from all Airbag modules.

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

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.

NOTE: This DTC will take 10 minutes to mature, allow plenty of time for the code to mature between as you
work through the test steps.

WARNING: To avoid personal injury or death, maintain a safe distance from all airbags while performing the
following steps.
Wiggle the wiring harness and connectors of the related airbag circuit or component.

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 the active DTC in ques-
tion.

Does the scan tool display any ACTIVE DTCs?

Yes

>> Select appropriate symptom from Symptom List.

>> No problem found at this time. Perform the Occupant Classification Module System Verification Test in

this Section. Erase all codes before returning vehicle to customer.

RESTRAINTS - ELECTRICAL DIAGNOSTICS

B1C2F-PASSENGER AIRBAG INDICATOR STATUS MISMATCH

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
After the Switch Bank bulb check is completed, the ORC compares the lamp request by the ORC (Set/Not Set)
and the (Set/Not Set) request by the Instrument Cluster Can bus messages. Each message is transmitted one
time per second or when a change in the lamp state occurs.

•

Set Condition:
If the lamp request by the ORC (On or Off), and the Lamp On by the Instrument Cluster (On or Off), messages
do not match, this code will set.

Possible Causes

OCCUPANT RESTRAINT CONTROLLER, INSTRUMENT CLUSTER MESSAGE MISMATCH

INSTRUMENT CLUSTER (CCN)

OCCUPANT RESTRAINT CONTROLLER (ORC)

Diagnostic Test

CHECK FOR AN ACTIVE DTC B1BB8-SRS WARNING INDICATOR STATUS MISMATCH

NOTE: Ensure the battery is fully charged.
Turn the ignition on, then off, and then on again.

With the scan tool, read Occupant Restraint Controller (ORC) DTCs.

Does the scan tool display active: B1C2F-PASSENGER AIRBAG INDICATOR STATUS MISMATCH?

Yes

>> Go To 2

>> Go To 5

CHECK FOR ACTIVE INSTRUMENT CLUSTER DTCs

With the scan tool, read Instrument Cluster DTCs.

Does the scan tool display and active Instrument Cluster DTCs?

Yes

>> Refer to symptom list for problems related to the Instrument Cluster.

Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.

>> Go To 3

CHECK THE ORC AND INSTRUMENT CLUSTER FOR LAMP STATUS

With the scan tool view the Instrument Cluster (CCN) Display.

Cycle the ignition key and observe the Passenger Airbag Indicator Lamp (PADL) Request status (Set/Not Set) dur-
ing the Instrument Cluster bulb check.

With the scan tool view the ORC Data Display.

Select Indicator Lamp Status from Bussed Inputs and select SRS Indicator Lamp request from the Bussed Outputs.

Cycle the ignition key and observe the Passenger Airbag Indicator Lamp (PADL) Status (Set/Not Set) during bulb
check.

Did the Data Display information match each other?

Yes

>> Go To 4

>> Replace the Instrument Cluster in accordance with the service information.

Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.
