SYSTEM DESCRIPTION
1. POWER BACK DOOR SYSTEM DESCRIPTION
(a) The power back door system controls the power back door by automatically opening and closing the power back door with a motor.
(1) The power back door system operates only when the necessary conditions are satisfied.
(2) The power back door ECU records the back door positions in the power back door ECU.
If the battery, power back door fuse, power back door ECU or back door motor unit is removed and then reinstalled, the power back door ECU loses the memory of the door positions.
In such cases, initialization of the power back door system is necessary. Refer
to the Initialization (See page ).
(3) "OPEN/CLOSE" request signals for the back door are received by the power back door ECU.
Then, the power back door ECU controls the back door opening/closing operation by sending commands to the back door lock assembly and back door motor unit.
(4) The power back door system has various request signals: "OPEN/CLOSE" request signal from the transmitter switch, "OPEN/CLOSE" request signal from the power back door control switch, "CLOSE" request signal from the power back door closer switch, and "OFF" request signal from the back door main switch.
(5) The power back door system sets off an alarm (using a buzzer) and hazard warning lights when the power back door starts operating.
(6) The power back door reverses the direction that the power back door is operating if any switch is pressed during operation.
(7) A pulse sensor and a touch sensor are used to prevent anything from being caught in the door while the power back door is closing (jam protection function).
(8) The power back door system stops motor operation and switches to the manual operation mode when the jam protection function is activated repeatedly more than the specified number of times.
(9) The power back door system slows the back door down when the back door approaches the fully opened position or fully closed position in order to reduce the impact against the vehicle body.
(b) Function of main components:
