B1865-PASSENGER WINDOW POSITION SENSOR CIRCUIT PERFORMANCE - PDM





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
Whenever the module is awake.

- Set Condition:
When one of the window motor hall sensors do not generate a signal within 1.25 ms during a window movement, this code will set.





Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTC's
Try to operate the Passenger Window up and down several times.
Wait 30 seconds.
With the scan tool, read DTC's.
Does the scan tool display B1865-PASSENGER 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.Body Verification Test
