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 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.





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 several times.
With the scan tool, read 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 BODY VERIFICATION TEST - VER 1. Body Verification Test

2. RELAY OPEN/SHORTED




NOTE: The Passenger Window Down Relay is located left of the steering column and taped to the harness.

Remove the Passenger Window Down Relay.
Install a substitute Relay in place of the Passenger Window Down Relay.
Turn the ignition on.
With the scan tool, erase DTCs.

With the scan tool, read DTCs.
Does the scan tool display 58-PASSENGER WINDOW DOWN RELAY OPEN/SHORT TO GROUND?

Yes

- Go To 3

No

- Replace the Window Down Relay.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

3. (A128) FUSED B(+) OPEN




Remove the Passenger Window Down Relay.
