PWC-10 < SYSTEM DESCRIPTION > SYSTEM • Encoder continues detecting the movement of front power window motor (driver side) and transmits to main power window and door lock/unlock switch as the encoder pulse signal while front power window motor (driver side) is operating. • Resistance is applied to the front power window motor (driver side) rotation that changes the frequency of encoder pulse signal if foreign material is trapped in the door glass. • Main power window and door lock/unlock switch controls to lower the window glass for 150 mm (5.9 in) after it detects encoder pulse signal frequency change. OPERATION CONDITION • When front door glass (driver side) AUTO-UP operation is performed (anti-pinch function does not operate just before the door glass closes and is fully closed). NOTE: Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it may lower. Fail Safe INFOID:0000000011278675 FAIL-SAFE CONTROL Switches to fail-safe control when malfunction is detected in encoder signal that detects up/down speed and direction of door glass. Switches to fail-safe control when error beyond regulation value is detected between the fully closed position and the actual position of the glass. It changes to condition before initialization and the following functions do not operate when switched to fail- safe control: • Auto-up operation • Anti-pinch function • Retained power function Perform initial operation to recover when switched to fail-safe mode. However, it switches back to fail-safe control when malfunction is found in power window switch or in the motor.
