For a complete wiring diagram Consult Diagrams/Electrical
- When Monitored:
Whenever the ignition is in the RUN or ACCESSORY position.
- Set Condition:
When the BCM senses that the voltage on the Passenger Window Switch Mux circuit is over 4.5 volts for longer than 31 milliseconds.
Diagnostic Test
1. DTC PRESENT
Turn the ignition on.
With the scan tool, erase DTCs.
Cycle the ignition switch from Off to Run.
Try to operate the Passenger Window Motor by using the Passenger Window Switch.
With the scan tool, read DTCs.
Does the scan tool display 4E-PASSENGER WINDOW SWITCH OPEN/SHORT TO VOLTAGE?
Yes
- Go To2
No
- The condition that caused the code to set is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
