B1BC8-PASSENGER SEAT WEIGHT SENSORS PERFORMANCE (CONTINUED)

INSPECT PASSENGER SEAT HARNESS WIRES & 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 chaffed, 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 OCS VERIFICATION TEST - VER 1.

>> Go To 5

PERFORM OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST

Verify that all of the Seat Weight Sensor mounting screws are torqued
to specification. Refer to 23 - BODY/SEATS.

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

NOTE: Failure to follow 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 Per-
formed 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; & 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 fol-
lows.

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 OCS VERIFICATION TEST - VER 1.

No - But Other DTCs Present

Diagnose and repair the DTCs. Refer to the Table of Contents in this Section for a complete list of
symptoms.

No - No Active DTCs Present

Perform OCS VERIFICATION TEST - VER 1.

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 diag-
nosing any stored codes.

WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Using the wiring diagram/schematic as a guide, inspect the wiring and
connectors.

Look for chaffed, pierced, pinched, or partially broken wires and bro-
ken, bent, pushed out, spread, corroded, or contaminated terminals.

The following additional checks may assist you in identifying a possi-
ble 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 fol-
lowing 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 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 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. Erase all codes before returning vehicle to customer.

For the Occupant Classification System circuit diagram (Refer to 8 - ELECTRICAL/RESTRAINTS - SCHEMATICS
AND DIAGRAMS).

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
While the CAN bus ignition status is RUN or SNA, the module checks the (F201) Fused Ignition Switch Output
(Run-Start) circuit voltage input range.

•

Set Condition:
With the ignition on, if voltage on the (F201) Fused Ignition Switch Output (Run-Start) circuit is equal to or
below 6.25 volts ±0.25 volts. Within 60 seconds of turning the ignition off, if voltage on the (F201) Fused Igni-
tion Switch Output (Run-Start) circuit is 2.4 to 5.0 volts.

Possible Causes

PASSENGER AIRBAG (PAB) INDICATOR RUN-START FUSE OPEN

(F201) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT SHORTED TO GROUND

(F201) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN

(F941) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN

PASSENGER AIRBAG ON/OFF INDICATOR LAMP

OCCUPANT CLASSIFICATION MODULE (OCM)

OCCUPANT RESTRAINT CONTROLLER (ORC)

Diagnostic Test

VERIFY THAT DTC B2101 IGNITION RUN/START INPUT CIRCUIT LOW IS ACTIVE

NOTE: Ensure the battery is fully charged.

NOTE: When reconnecting Airbag system components, the igni-
tion must be turned off and the battery must be disconnected.
Turn the ignition on, then off, and then on again.

With the scan tool, read Occupant Classification Module (OCM) DTCs.

Does the scan tool display active: B2101 IGNITION RUN/START
INPUT CIRCUIT LOW?

Yes
