Diagnostic Test
1. TEST FOR INTERMITTENT CONDITIONTurn the ignition on.
With the scan tool, record and erase DTC's
Try to operate the Driver Window up and down several times.
Wait 30 seconds.
With the scan tool, read DTC's.
Does the scan tool display B185A–DRIVER WINDOW POSITION SENSOR CIRCUIT PERFORMANCE?
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. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
2. (Q301) DRIVER WINDOW HALL SENSOR A SIGNAL SHORT TO GROUND

- Repair the (Q301) Driver Window Hall Sensor A Signal circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
Yes
- Go To 5
5. (Q303) DRIVER WINDOW HALL SENSOR B SIGNAL CIRCUIT OPEN
Measure the resistance of the (Q303) Driver Window Hall Sensor B Signal circuit between the Motor connector and the Module C1 connector.
Is the resistance below 1.0 ohms?
No
- Repair the (Q303) Driver Window Hall Sensor B Signal circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
Yes
- Go To 6
6. (Q303) DRIVER WINDOW HALL SENSOR B SIGNAL CIRCUIT SHORTED TO THE (Q991) DRIVER WINDOW HALL SENSOR RETURN CIRCUIT
