B2581
B2581 - Passenger Window Position Sensor(s) No Signal
For a complete wiring diagram, refer to.
• When Monitored: Whenever the module is awake.
• Set Condition: The window motor hall sensor does not generate a signal during a window movement.
• If there are any other power window DTCs, repair them before continuing.
Test Step 1 - Test for an Intermittent Condition
• Turn the ignition ON.
• With the scan tool, erase all DTCs.
• Try to operate the passenger window UP and DOWN several times.
• Wait 30 seconds.
• With the scan tool, check for DTCs.
Does the scan tool display this DTC?
Yes
• Go to Test Step 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. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 2 - Check Voltage on the Q306 Passenger Window Hall Sensor Supply Circuit
• Turn the ignition off.
• Disconnect the passenger window motor harness connector.
• Turn the ignition on.
• Measure the voltage between ground and the Q306 passenger window hall sensor supply circuit.
Is the voltage above 11.0 volts?
Yes
• Go to Test Step 5
No
• Go to Test Step 3
Test Step 3 - Q306 Passenger Window Hall Sensor Supply Circuit for an Open
• Turn the ignition off.
• Disconnect the passenger door module C4 harness connector.
• Measure the resistance of the Q306 passenger window hall sensor supply circuit between the passenger window motor harness connector and the passenger door module C4 harness connector.
Is the resistance below 10.0 Ohms?
Yes
• Go to Test Step 4
No
• Repair the (Q306) passenger window hall sensor supply circuit for an open.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 4 - Q306 Passenger Window Hall Sensor Supply Circuit for a Short to Ground
• Measure the resistance between ground and the Q306 passenger window hall sensor supply circuit.
Is the resistance above 10k Ohms?
Yes
• Replace the passenger door module.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Repair the Q306 Passenger Window Hall Sensor Supply circuit for a short to ground.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 5 - Q302 Passenger Window Hall Sensor A Signal Circuit for an Open
• Measure the resistance of the Q302 passenger window hall sensor A signal circuit between the passenger window motor connector and the passenger door module C4 connector.
Is the resistance below 10.0 Ohms?
Yes
• Go to Test Step 6
No
• Repair the Q302 passenger window hall sensor A signal circuit for an open.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 6 - Q302 Passenger Window Hall Sensor A Signal Circuit for a Short to Ground
• Measure the resistance between ground and the Q302 passenger window hall sensor A signal circuit.
Is the resistance above 10k Ohms?
Yes
• Go to Test Step 7
No
• Repair the Q302 passenger window hall sensor A signal circuit for a short to ground.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 7 - Q306 Passenger Window Hall Sensor Supply Circuit for an Open
• Measure the resistance of the Q990 passenger window passenger sense return circuit between the passenger window Motor connector and the passenger door module C4 connector.
Is the resistance below 5.0 Ohms?
Yes
• Replace the passenger power window motor.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Repair the Q990 passenger window hall sensor return circuit for an open.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
