The power window regulator motor is driven by operating the power window regulator switch. The power window regulator motor consists of the motor, regulator and ECU.

This DTC is stored when the power window regulator motor has a malfunction, or the ECU built into the power window regulator motor determines that the fully closed window position has deviated approximately 20 mm (0.787 in.) or more from the normal position.

HINT:
