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 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 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.

Vehicle security system
Your vehicle has two types of security systems:
Vehicle security system NISSAN Vehicle Immobilizer SystemThe vehicle security system provides visual and audible alarm signals if someone opens the doors, liftgate or the hood when the system is armed. It is not, however, a motion detection type system that activates when a vehicle is moved or when a vibration occurs.
