POWER WINDOW LOCK FUNCTION
Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock switch is ON. This inhibits power window switch operation except with the main power window and door lock/ unlock switch.
ANTI-PINCH OPERATION (FRONT LH)
OPERATION CONDITION
NOTE:
Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it may lower.
Fail-safe
FAIL-SAFE CONTROL
Switches to fail-safe control when malfunction is detected in the encoder signal that detects UP/DOWN speed and direction of door glass. Switches to fail-safe control when an error beyond the regulation value is detected between the fully closed position and the actual position of the glass.
Malfunction | Malfunction condition |
Pulse sensor malfunction | When only one side of pulse signal is being detected for more than the specified value. |
Both pulse sensors malfunction | When both pulse signals have not been detected for more than the specified value during glass open/close operation. |
Pulse direction malfunction | When the pulse signal that is detected during glass open/close operation detects the opposite condition of power window motor operating direction. |
Glass recognition position malfunction 1 | When it detects the error between glass fully closed position in power window switch memory and actual fully closed position during glass open/close operation is more than the specified value. |
Glass recognition position malfunction 2 | When it detects pulse count more that the value of glass full stroke during glass open/close operation. |
Malfunction of not yet updated closed position of glass | When glass open/close operation is continuously performed without fully closing more that the specified value (approximately 10 strokes). |
It changes to condition before initialization and the following functions do not operate when switched to failsafe control:
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.
