    3. Jam Protection Control


      1. The slide door ECU detects whether an overload has been applied to the power slide door by the change in the touch sensor (power slide door sensor assembly) or power slide door motor current value. When this occurs, the slide door ECU reverses, and then stops the slide door.

        Control during Detection of Overload (Jam)
        Detection Method Control
        Touch sensor (power slide door sensor assembly) output signal During close operation Reverses 100 mm and stops*
        Change in power slide door motor current value During close operation Reverses 100 mm and stops*
        During open operation Reverses 100 mm and stops*

        Tech Tips

        *: Slide door operation stops for a maximum of 30 minutes (magnetic clutch engaged). If 30 minutes elapse, the buzzer sounds for 2 seconds and the system activates strong brake/clutch control to prevent battery depletion.

    4. Brake/Clutch Control


      1. If the speed of the slide door reaches or exceeds a specified value by manual open or close operation of the slide door or through the weight of the slide door, the power slide door motor stops and the magnetic clutch is operated in order to reduce the slide door moving speed.

      2. Brake/clutch control operates regardless of whether the power slide door main switch is on or off.

      3. When the speed of the slide door reaches or exceeds the specified value (approximately 1 m/sec.) and all of the following conditions are met, brake/clutch control starts. Also, brake/clutch control is ended by fully closing the slide door.

        Brake/Clutch Control Start Condition

        • Slide door is not in the fully closed position.

    5. Strong Brake/Clutch Control


      1. When manual mode (manual opening and closing of the slide door) is activated, if the moving speed of the slide door is at a specified value or more, the magnetic clutch is operated in order to reduce the slide door moving speed.

      2. When any of the following conditions are met and the moving speed of the slide door via manual operation is at a specified value (approximately 0.25 m/sec.) or more, strong brake/clutch control activates.

        Strong Brake/Clutch Control Start Condition

        • The operation conditions are not met during a slide door open operation.

        • The operation conditions are not met during a slide door close operation.

        • A certain period of time elapses after suspend control.

        • The power slide door main switch is turned off during suspend control.

      3. When any of the following conditions are met after strong brake/clutch control activates, control ends.

        Strong Brake/Clutch Control End Condition

        • Approximately 12 seconds elapse after control starts.

        • The slide door does not move for approximately 1 second.

        • The slide door closer function operates (when the power slide door main switch is on).

        • The slide door is fully closed.

    6. Intermittent Clutch Control


      1. When the speed of the slide door cannot be detected due to a pulse sensor (door sensor) malfunction, the magnetic clutch operates intermittently and slows the slide door.

      2. Intermittent clutch control starts when the following condition is met. If approximately 20 seconds elapse after control starts or the slide door fully closes, intermittent clutch control is ended.

        Intermittent Clutch Control Start Condition

        • A pulse sensor (door sensor) malfunction is detected during a slide door open or close operation.
