Circuit/System Description



The driver door switch (DDS) and passenger door switch (PDS) control the power window functions through the power window motor up and down



control circuits. The door switches monitor the control circuits for fault conditions when up or down operation is requested prior to activating the



function and during operation.

* The ignition is ON.

B3205 0B



The DDS or PDS has detected excessive current flow on their respective window motor control circuit.



Action Taken When the DTC Sets



The affected power window will be inoperative.



Conditions for Clearing the DTC



* The DTC will be current for as long as the fault is present.



* When the fault is no longer present, the DTC will be a history DTC.
