B2580
B2580 - Driver Window Position Sensor 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.
Test Step 1 - Test for an Intermittent Condition
• Turn the ignition ON.
• With the scan tool, erase all DTCs.
• Try to operate the driver 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
• The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 2 - Check Voltage On the Driver Window Hall Sensor Supply Circuit
• Turn the ignition OFF.
• Disconnect the driver window motor connector.
• Turn the ignition ON.
• Measure the voltage between ground and the driver window hall sensor supply circuit.
Is the voltage more than 11.0 volts?
Yes
• Go to Test Step 5
No
• Go to Test Step 3
Test Step 3 - Driver Window Hall Sensor Supply Circuit Open
• Turn the ignition OFF.
• Disconnect the driver door module C4 harness connector.
• Measure the resistance of the driver window hall sensor supply circuit between the driver window motor harness connector and the driver door module C4 harness connector.
Is the resistance less than 5.0 ohms?
Yes
• Go to Test Step 4
No
• Repair the driver window hall sensor supply circuit for an open.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 4 - Driver Window Hall Sensor Supply Circuit Short to Ground
• Measure the resistance between ground and the driver window hall sensor supply circuit.
Is the resistance more than 10k ohms?
Yes
• Replace the driver door module.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Repair the driver 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 - Driver Window Hall Sensor A Signal Circuit for an Open
• Turn the ignition OFF.
• Disconnect the driver door module C4 harness connector.
• Measure the resistance of the driver window hall sensor A signal circuit between the driver window motor connector and the driver door module C4 connector.
Is the resistance less than 10.0 ohms?
Yes
• Go to Test Step 6
No
• Repair the driver 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 - Driver Window Hall Sensor A Signal Circuit for a Short to Ground
• Measure the resistance between ground and the driver window hall sensor A signal circuit.
Is the resistance more than 10k ohms?
Yes
• Go to Test Step 7
No
• Repair the driver 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 - Driver Window Hall Sensor Return Circuit Open
• Measure the resistance of the driver window hall sensor return circuit between the driver window motor connector and the driver door module C4 connector.
Is the resistance less than 5.0 ohms?
Yes
• Replace the driver window motor.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Repair the driver window hall sensor return circuit for an open.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
