- When Monitored:
Whenever the module is awake.
- Set Condition:
When the Passenger Window Hall Sensor Supply circuit falls below 0.8 of a volt for over 480 ms., this code will set.
1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Operate the Passenger Window up and down several times.
4. Wait 30 seconds.
5. With the scan tool, read DTCs.
Does the scan tool display B1863-PASSENGER WINDOW POSITION SENSOR POWER SUPPLY LOW?
Yes
- Go To 2
No
- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
