DESCRIPTION
When the engine is running or the ignition switch is ON, the power window regulator motor assembly (for rear RH side) is operated by the power window regulator switch assembly (for rear RH side). The power window regulator motor assembly (for rear RH side) has motor, regulator, and ECU functions.
HINT:
If the pulse sensor built into the power window regulator motor (for rear RH side) malfunctions, the power window control system enters fail-safe mode. The remote up/down and auto up/down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the power window regulator switch assembly (for rear RH side) at the auto up position, and opened manually by pushing down the power window regulator switch assembly (for rear RH side).
