B2581

B2581-PASSENGER WINDOW POSITION SENSOR(S) NO SIGNAL- PDM





For a complete wiring diagram Refer to Diagrams/Electrical.

- When Monitored:

Whenever the window motor is operating.

- Set Condition:

When the Window Hall Position Sensor(s) circuits fall below 1.2 volts for over 315 ms, during a window movement, this code will set.





Diagnostic Test

1.TEST FOR INTERMITTENT CONDITION

Turn the ignition on.

With the scan tool, record and erase DTC's.

Operate the Passenger Window up and down several times.

Wait 30 seconds.

With the scan tool, read DTC's.

Does the scan tool display B2581-PASSENGER WINDOW POSITION SENSOR(S) NO SIGNAL?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. HALL SENSOR SUPPLY CIRCUIT OPEN





With the scan tool, erase DTC's.

Turn the ignition off.

Disconnect the Passenger Window Motor connector.

Measure the voltage between the (Q306) Passenger Window Hall Sensor Supply circuit and Ground.

Turn the ignition on.

Is the voltage above 9.5 volts?

No

- Go To 3

Yes

- Go To 4

3. HALL SENSOR SUPPLY CIRCUIT OPEN





Turn the ignition off.

Disconnect the Passenger Door Module C2 connector.

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.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Repair the (Q306) Passenger Window Hall Sensor Supply circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

4.BOTH PASSENGER WINDOW HALL SENSOR A AND B SIGNAL CIRCUITS OPEN





Turn the ignition off.

Disconnect the Passenger Door Module C2 connector.

Measure the resistance of the (Q302) Passenger Window Hall Sensor A Signal circuit between the Module connector and the Motor connector.

Measure the resistance of the (Q304) Passenger Window Hall Sensor B Signal circuit between the Module connector and the Motor connector.

Is the resistance below 2.0 ohms on both circuits?

No

- Repair both of the Passenger Window Hall Sensor Signal circuits for opens.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

Yes

- Replace the Passenger Window Motor.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
