B1865

B1865-31-PASSENGER WINDOW POSITION SENSOR - NO SIGNAL





For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

The window motor contains a hall effect sensor to detect the window position. A hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field. If the motor looses its counts, it may perform erratically or in very short movements.

- When Monitored:
Whenever the power is turned off to the module and it goes from being awake to sleep mode.

- Set Condition:
When the Passenger Window Hall Sensor Supply circuit is above 1.5 volts for over 15 ms. and the power to the module has been turned off, this code will set.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase the DTCs.
3. Operate the Passenger Window up and down several times.
4. Wait 30 seconds.
5. With the scan tool, read the DTCs.

Does the scan tool display; B1865-31-PASSENGER WINDOW POSITION SENSOR - NO SIGNAL?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. (Q306) PASSENGER WINDOW HALL SENSOR SUPPLY CIRCUIT SHORTED TO VOLTAGE




1. Turn the ignition off.
2. Disconnect the Passenger Door Module C4 harness connector.
3. Turn the ignition on.
4. Measure the voltage between ground and the (Q306) Passenger Window Hall Sensor Supply circuit.

Is there any voltage present?

Yes

- Repair the short to voltage in the (Q306) Passenger Window Hall Sensor Supply circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Passenger Door Module. Door Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
