For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams

- When Monitored:
Whenever the ignition is in the Run or Accessory position.

- Set Condition:
When the BCM turns on the Passenger Window Down Relay Control circuit and does not detect 8.0 volts or greater within 10 seconds, this code will set.





1. DTC PRESENT
1. Turn the ignition on.
2. With the scan tool, erase the DTCs.
3. Cycle the ignition switch from Off to Run.
4. Try to operate the Passenger Window Motor several times.
5. With the scan tool, read the DTCs.

Does the scan tool display 58-PASSENGER WINDOW DOWN RELAY COIL OPEN/SHORT TO GROUND?

Yes

- Go To 2

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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
