B1B94 Passanger Seat Track Position Sensor Circuit High

B1B94 code - When the Occupant Restraint Controller (ORC) sends a test current to the seat track position sensors to verify the integrity of the sensor and wiring. The use of the ORC adapter tool in the test below provides a test point in place of the module. While the CAN bus ignition status is in IGN RUN and the module in configured for a passanger seat track position sensor, the module checks the sensor input current ranges.

If the Module detects that the sensor input is greater than or equal to 20.5 mA. This DTC may set when the current is between 17 mA and 20.5 mA.

Possible causes B1B94 code:
- Passanger seat harness improperly routed
- Passanger seat harness wires chafed, pierced, pinched, partilaly broken
- Passanger seat harness connector terminals broken, bent, pushed out, spread, corroded, contaminated
- Passanger seat position sensor data circuit shorted to voltage
- Passanger seat position sensor voltage circuit shorted to voltage
- Passanger seat track position sensor
- Occupant Restraint Controller (ORC)

Diagnostic test B1B94 code

Step 1. Identifying vehicle equipment

Make sure the battery is fully charged. Turn the ignition on, with the scan tool read ORC active DTCs.

Does the scan tool display: B1B94 PASSANGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?

Yes, go to step 2.
No, perform the Airbag intermittent.

Step 2. Check for active internal faults, ignition faults, and battery fault in the Occupant Restraint Controller (ORC)

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

Does the scan tool display any active DTCs relating to internal faults, ignition faults, or battery faults?

Yes, refer to sitemap DTC B codes (SRS) and perform appropriate diagnostic procedure.
No, go to step 3.

Step 3. Inspect passanger seat harness wires and connectors

Turn the ignition off, disconnect the 12 volt battery and wait two minutes before proceeding. Filure to follow these instructions may result in possible serious or fatal injury. Using the wiring diagram/schematic as a guide, inspect the passanger seat harness and connectors. Look for chafed, pierced, pinched, or partially broken wires, bent, pushed out, or spread, corroded, or contaminated terminals.

Are any of these conditions present?

Yes, 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 passanger seat harness.

No, go to step 4.

Step 4. Verify that the passanger seat harness is routed correctly

Verify that the passanger seat harness is routed correctly.

Is the passanger seat harness routed correctly?

Yes, go to step 5.
No, rerouted the passanger seat harness as necessary.

Step 5. Check for DTC B1B94 PASSANGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH WITH PASSANGER SEAT TRACK POSITION SENSOR DISCONNECTED

Turn the ignition off, disconnect the 12 volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. Disconnect the passanger seat track position sensor harness connector. Wait two minutes, and then with the scan tool read ORC DTCs.

Does the scan tool display: B1B94 PASSANGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?

Yes, go to step 6.
No, replace the passanger seat track position sensor.

Step 6. Check passanger seat position sensor data circuit and passanger seat position sensor voltage circuit for a short to voltage

Turn the ignition off, disconnect the 12 volt battery and wait two minutes before proceeding. Disconnect the both ORC harness connectors.
Turn the ignition on, then reconnect the 12 volt battery and wait two minutes before proceeding. Measure the voltage of the passanger seat position sensor data circuit at the passanger seat track position sensor harness connector.
Measure the voltage of the passanger seat position sensor voltage circuit at the passanger seat track position sensor harness connector.

Is the voltage above 0.2 of a volt on either circuit?

Yes, do no 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 passanger seat harness.

No, if the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Replace the ORC.
