Diagnostic Test

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

      Does the scan tool display B185A-DRIVER WINDOW POSITION SENSOR CIRCUIT PERFORMANCE?

      Yes 

      • Go To  2.
