B185A
B185A-DRIVER WINDOW POSITION SENSOR CIRCUIT PERFORMANCE
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
Whenever the module is awake.
- Set Condition:
When one of the window motor hall sensors does not generate a signal during a window movement, this code will set.
1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase the DTCs.
3. Try to operate the Driver Window up and down several times.
4. Wait 30 seconds.
5. With the scan tool, read the active DTCs.
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 the BODY VERIFICATION TEST. Body Verification Test.
2. (Q301) DRIVER WINDOW HALL SENSOR A SIGNAL SHORT TO GROUND
