B2515-REAR WINDOW POSITION SENSOR SUPPLY CIRCUIT LOW







- 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.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase the DTCs.
3. Operate both rear windows up and down several times.
4. Wait 30 seconds.
5. With the scan tool, read the DTCs.

Does the scan tool display B2515-REAR WINDOW POSITION SENSOR SUPPLY CIRCUIT LOW?

Yes

- Go To 2

No

- The condition that caused this symptom is currently not present. With the scan tool, check the Environmental Data to help identify the conditions in which the DTC was set. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
