For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
Whenever the module is awake.

- Set Condition:
When if either the Left Rear or Right Rear Window Hall Sensor Supply circuit falls below 2.0 volts of battery voltage for over 500ms.,this code will set.





Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTC's
Operate both rear windows up and down several times.
Wait 30 seconds.
With the scan tool, read DTC's.
Does the scan tool display B2515-REAR WINDOW POSITION SENSOR SUPPLY CIRCUIT LOW?

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.
