B185D - Passenger Window Switch - Stuck






For a complete wiring diagram, refer to.

• When Monitored: Whenever the module is awake.

• Set Condition: When the passenger window switch MUX circuit is resisted below 1.7 volts for over 30 seconds.






Test Step 1 - Test for an Intermittent Condition

• Turn the ignition ON.

• With the scan tool, record and erase DTCs

• Operate the passenger window switch in all positions several times.

• Wait 30 seconds.

• With the scan tool, check for DTCs.

Does the scan tool display B185D - Passenger Window Switch Stuck?

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.
