B1B97

B1B97-PASSENGER SEAT TRACK POSITION SENSOR CONFIGURATION MISMATCH





For a complete wiring diagram Consult Diagrams/Electrical.

Theory of Operation

When powered, the Occupant Classification module (OCM) sends a test current to the Passenger Seat Track Position Sensors terminals. During this test, the sensors discovered are checked for agreement with the pre-programmed configuration of components assigned to the module.

- When Monitored:
The OCM checks for the presence of Passenger Seat Track Position Sensors circuits once at every power up, during the initialization process.

- Set Condition:
This DTC sets when the OCM is not configured for a Passenger Seat Track Position Sensor and the OCM detects a valid Passenger Seat Track Position Sensor present.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure

Diagnostic Test

1. VERIFY THAT B1B97-PASSENGER SEAT TRACK POSITION SENSOR CONFIGURATION MISMATCH IS ACTIVE
NOTE: Ensure the battery is fully charged.

With the scan tool, read OCM DTC.
Does the scan tool display any active B1B97-PASSENGER SEAT TRACK POSITION SENSOR CONFIGURATION MISMATCH?

Yes

- Go To 2

No

- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Verification Tests

2. VERIFY OCM PART NUMBER
With the scan tool, read the OCM part number.
Does the OCM have the correct part number for this vehicle?

Yes

- Go To 3

No

WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

WARNING: If the Occupant Classification Module (OCM) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and serious or fatal injury.

CAUTION: Disconnecting or connecting the OCM connectors with the battery connected will permanently damage the OCM.

- Replace the OCM.
- Perform the *OCM REZERO. Restraint System

3. INSPECT PASSENGER SEAT HARNESS WIRES AND CONNECTORS
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Using the wiring diagram / schematic as a guide, inspect the Passenger Seat wiring and connectors. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
Are any of these conditions present?

Yes

- Go To 4

No

- Replace the Passenger Seat wiring.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Verification Tests

4. VERIFY SENSOR CONFIGURATION
Disconnect the Passenger Seat Position Sensor.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

With the scan tool, read OCM DTC.
Does the scan tool display active: B1B97-PASSENGER SEAT TRACK POSITION SENSOR CONFIGURATION MISMATCH?

Yes

WARNING: If the Occupant Classification Module (OCM) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and serious or fatal injury.

CAUTION: Disconnecting or connecting the OCM connectors with the battery connected will permanently damage the OCM.

- Replace the OCM.
- Perform the *OCM REZERO. Restraint System

No

- Tape the Passenger Seat Position Sensor connector and harness to the seat.
- Remove the Passenger Seat Position Sensor.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Verification Tests
