B2581

B2581-PASSENGER WINDOW POSITION SENSOR(S) NO SIGNAL







NOTE: In the above schematic, the motor connector shows RHD. Starting in 2010, this connector is used on RHD and LHD.

- When Monitored:
Whenever the window motor is operating.

- Set Condition:
When the door module does not sense a pulse from the hall sensor, during a window movement, 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 active DTCs.

Does the scan tool display B2581-PASSENGER WINDOW POSITION SENSOR(S) 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 poor pin fit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. (Q306) HALL SENSOR SUPPLY CIRCUIT OPEN




1. With the scan tool, erase the DTCs.
2. Turn the ignition off.
3. Disconnect the Passenger Window Motor connector.
4. Turn the ignition on.
5. Measure the voltage between the (Q306) Passenger Window Hall Sensor Supply circuit and Ground.

Is the voltage above 9.5 volts?

Yes

- Go To 4

No

- Go To 3

3. (Q306) HALL SENSOR SUPPLY CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the Passenger Door Module (PDM) C4 connector.
3. Measure the resistance of the (Q306) Passenger Window Hall Sensor Supply circuit between the Module connector and the Motor connector.

Is the resistance below 2.0 Ohms?

Yes

- Replace the Passenger Door Module (PDM).
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the (Q306) Passenger Window Hall Sensor Supply circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. (Q302) PASSENGER WINDOW HALL SENSOR A SIGNAL CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the Passenger Door Module (PDM) C4 connector.
3. Measure the resistance of the (Q302) Passenger Window Hall Sensor A Signal circuit between the Module connector and the Motor connector.

Is the resistance below 2.0 Ohms?

Yes

- Go To 5

No

- Repair the (Q302) Passenger Window Hall Sensor Signal A circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. (Q990) PASSENGER WINDOW HALL SENSOR RETURN CIRCUIT OPEN




1. Measure the resistance of the (Q990) Passenger Window Hall Sensor Return circuit between the Module connector and the Motor connector.

Is the resistance below 2.0 Ohms?

Yes

- Replace the Passenger Window Motor (regulator) in accordance with the Service Information.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the (Q990) Passenger Window Hall Sensor Return circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
