PWC-80 < ECU DIAGNOSIS INFORMATION > FRONT POWER WINDOW SWITCH Fail Safe INFOID:0000000006161115 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 motor. 15 (G/W) 3 Encoder pulse signal 2 Input When power window motor op- 16 (LG/W) Ground Power window serial link Input/ Output IGN SW ON or power window Terminal No. (Wire color) Description Condition Voltage [V] (Approx.) + – Signal name Input/ Output JMKIA0070GB JPMIA0013GB Error Error condition Pulse sensor malfunction When only one side of pulse signal is being detected for more than the specified value.
