PASSENGER BTS SHORT TO GROUND

For a complete wiring diagram Refer to Section 8W.


  • When Monitored:

    With the ignition on.

  • Set Condition:

    If the Occupant Classification Module (OCM) detects Belt Tension Sensor A/D counts are less than 13.



Diagnostic Test

1.DETERMINE ACTIVE OR STORED DTC

NOTE: Ensure that the battery is fully charged.




SELECT ACTIVE or STORED DTC:

ACTIVE DTC
  • Refer to *Belt Tension Sensor / Pressure Sensor Faults for the diagnostic procedure.


STORED DTC
  • Go To 2

2.CHECK THE PASSENGER BELT TENSION SENSOR OUTPUT WITH NO LOAD APPLIED TO THE SENSOR

NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to the Table of Contents in this Section for a complete list of airbag system diagnostic procedures.






Is the Passenger BTS Output between 39 and 69?

Yes
  • Go To 3


No
  • Replace the Front Passenger Seat Belt Retractor and Passenger Belt Tension Sensor Assembly in accordance with the Service Information.
  • Perform BELT TENSION SENSOR VERIFICATION TEST.

3.CHECK THE PASSENGER BELT TENSION SENSOR OUTPUT WITH A LOAD APPLIED TO THE SENSOR

  • Connect the hook at the bottom of the spring scale through the Passenger Belt Tension Sensor webbing loop so that the end of the hook faces the passenger seat.
  • Place the maximum reading indicator at the bottom of the spring scale.
  • Grab the horizontal bar at the top of the spring scale. Pull the spring scale straight upward keeping the horizontal bar level with the door sill and the spring scale in-line with the Passenger Belt Tension Sensor.
  • Apply and hold 11 kg (24 lbs) to 12 kg (26 lbs) of pressure on the sensor while an assistant monitors the Passenger Belt Tension Sensor Output on the scan tool display.


Is the Passenger BTS Output between 153 and 204 with 11 kg (24 lbs) to 12 kg (26 lbs) of pressure applied to the sensor?

Yes
  • Maintain the 24 to 26 lbs of pressure on the Passenger Belt Tension Sensor and Go To 4


No
  • Replace the Front Passenger Seat Belt Retractor and Passenger Belt Tension Sensor Assembly in accordance with the Service Information.
  • Perform BELT TENSION SENSOR VERIFICATION TEST.

4.CHECK THE PASSENGER BELT TENSION SENSOR OUTPUT WITH THE LOAD RELEASED



Does the Passenger BTS Output return to between 39 and 69 within 20 seconds of releasing the load?

Yes
  • Go To 5


No
  • Replace the Front Passenger Seat Belt Retractor and Passenger Belt Tension Sensor Assembly in accordance with the Service Information.
  • Perform BELT TENSION SENSOR VERIFICATION TEST.

5.INSPECT THE OCCUPANT CLASSIFICATION SYSTEM (OCS) WIRING AND CONNECTORS FOR CONDITIONS THAT CAUSED THE DTC(s) TO SET


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




Are any of these conditions present?

Yes

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

    NOTE: The Occupant Classification Module (OCM) and the Passenger Seat Bladder and Cushion Kit are the only serviceable OCS components.

  • Replace the OCS Bladder and Cushion Kit in accordance with the Service information.
  • Perform SYSTEM VERIFICATION REQUIRED test.
  • Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.


No
  • Go To 6

6.TEST FOR AN INTERMITTENT CONDITION


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


  • Wiggle the wiring harness and connectors of the related circuit.
  • If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
  • Continue the test until either a code becomes active or the problem area is isolated.



Are any ACTIVE DTCs present?

Yes
  • Select the appropriate diagnostic procedure from the Table of Contents in this section.


No
  • No problem found at this time. Erase all codes before returning the vehicle to the customer.
