For a complete wiring diagram, refer to.

• When Monitored: Whenever the window motor is operating.

• Set Condition: The passenger window motor UP circuit does not change from low to high after 30 seconds.






Test Step 1 - Test for an Intermittent Condition

• Turn the ignition ON.

• With the scan tool, erase all DTCs.

• Try to operate the passenger window UP and DOWN several times.

• Wait 30 seconds.

• With the scan tool, check for DTCs.

Does the scan tool display B185F - Passenger Window Control Circuit Low?

Yes

• Go to Test Step 2

No

• The condition that caused this symptom is currently not present. 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.
