URATION MISMATCH DTCs?

Yes

>> For active DTC-Go To 2

Yes

>> For stored-Go To 6

>> Perform *OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST.

REPLACE THE ORC

When Monitored:
While the CAN bus ignition status is in IGN_RUN, the module checks the sensor supply.

•

Set Condition:
If the OCM detects that the sensor supply shorted. NOTE: A shorted supply circuit will cause a ’NO
RESPONSE FROM OCM” condition.

Possible Causes

OCS SUPPLY CIRCUIT SHORTED

OCCUPANT CLASSIFICATION MODULE (OCM)

Diagnostic Test

VERIFY THAT B1BBA-PASSENGER SEAT WEIGHT SENSOR SUPPLY CIRCUIT DTC IS ACTIVE

With the scan tool, read OCM DTCs.

Does the scan tool display active: B1BBA-PASSENGER SEAT WEIGHT SENSOR SUPPLY CIRCUIT?

Yes

>> Replace the OCM in accordance with the Service Information.

Perform the OCS VERIFICATION REQUIRED procedure.

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 3

TEST FOR INTERMITTENT CONDITION

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

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.

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.
