1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, erase all DTC's.
3. Try to operate the Driver Window up and down several times.
4. Wait 30 seconds.
5. With the scan tool, read DTC's.

Does the scan tool display this DTC?

Yes

- Go To 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 BODY VERIFICATION TEST Body Verification Test.

2. CHECK VOLTAGE ON THE (Q305) DRIVER WINDOW HALL SENSOR SUPPLY CIRCUIT




1. Turn the ignition off.

Yes

- Go To 6

No

- Repair the (Q301) Driver Window Hall Sensor A Signal circuit for an open.
- Perform BODY VERIFICATION TEST Body Verification Test.

6. (Q301) DRIVER WINDOW HALL SENSOR A SIGNAL CIRCUIT FOR A SHORT TO GROUND




1. Measure the resistance between ground and the (Q301) Driver Window Hall Sensor A Signal circuit.

Is the resistance above 10k ohms?

Yes

- Go To 7

No

- Repair the (Q301) Driver Window Hall Sensor A Signal circuit for a short to ground.
- Perform BODY VERIFICATION TEST Body Verification Test.

7. (Q991) DRIVER WINDOW HALL SENSOR RETURN CIRCUIT OPEN
