B1B8E-Driver Seat Track position sensor circuit high

B1B8E Code - While the CAN Bus ignition status is in Ignition-RUN and the Occupant Restraint Controller (ORC) or Airbag Module is configured for a driver seat track position sensor, the Occupant Restraint Controller (ORC) check the sensor input current ranges.

Set condition, if the ORC 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 20.0 mA.

Possible causes:

• Driver seat harness improperly routed.
• Driver seat harness wires chafed, pierced, pinched, partially broken.
• Driver seat harness connector terminals broken, bent, pushed out, spread, corroded, contaminated.

• Driver seat position sensor signal circuit shorted to voltage.
• Driver seat position sensor supply circuit shorted to voltage.
• Driver seat position sensor signal circuit short to the driver seat position sensor supply circuit
• Driver seat track position sensor.
• Occupant Restraint Controller (ORC) / Airbag Module.

Diagnose code B1B8E-Driver seat track position sensor circuit low

Step 1. Identifying vehicle equipment

Note : Make sure the battery is fully charged.

Turn the ignition on, with the scan tool, read ORC active DTC.

Does the scan tool display active DTC B1B8E-Driver seat track position sensor circuit high ?

YES, go to step 2.

NO, go to step 8.

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

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

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

YES, refer to Sitemap/Labels-DTC B Codes (SRS) and perform the appropriate diagnostic procedure.

NO, go to step 3.

Step 3. Inspect driver seat harness wires and connectors

Using the wiring diagram/schematic as a guide, inspect the Driver seat harness 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, replace the Driver seat harness.

NO, go to step 4.

Step 4. Verify that Driver seat harness is routed correctly

Verify that the Driver seat harness is routed correctly.

Is the Driver seat harness routed correctly ?

YES, go to step 5.

NO, reroute the Driver seat harness as necessary.

(Sorry!!! Step 5-6, refer to code B1B8F)
Step 5. Check for DTC B1B8E-Driver seat track position sensor circuit high with driver seat track position sensor disconnected

Step 6. Check Driver seat position sensor signal circuit and Driver seat position sensor supply circuit for a short to voltage

Step 7. Check Driver seat position sensor signal circuit for a short to Driver seat position sensor supply circuit

Step 8. Test for an intermittent condition
