SYSTEM (AUTOMATIC BACK DOOR SYSTEM)

INTERMITTENT CLUTCH FUNCTION

If the main switch is turned to OFF during auto operation, the back door may be closed suddenly because the
operation is interrupted immediately when the operation cannot be continued because of the detection of a
system malfunction. Therefore, operate the clutch intermittently to stabilize the back door behavior and ensure
safety.

NOTE:
Output sequence for half latch switch, open switch, and close switch may vary depending on reaction force dif-
ference of back door weather-strip. When reaction force of back door weather-strip is strong, refer to a broken
line in the chart.

When reaction force of back door weather-strip is not strong

1.

Buzzer and hazard lamp operate after condition are satisfied.

2.

After buzzer operation (pattern A), back door closure motor starts the open operation.

3.

When the latch is released and reaction force of weather-strip is not strong, half latch switch does not turn
ON, and back door closure motor stops the open operation when open switch turns ON. After this opera-
tion, automatic back door motor and magnet clutch operate, and then back door starts the open operation.

4.

When door is lifted up, half latch switch turns ON, and then back door closure motor operates the reverse
operation and starts returning to the neutral position.

5.

When close switch turns OFF, back door closure motor stops the reverse operation and then completes
returning to the neutral position.

When reaction force of back door weather-strip is strong

1.

Buzzer and hazard lamp operate after condition are satisfied.

2.

After buzzer operation (pattern A), back door closure motor starts the open operation.

3.

When the latch is released, half latch switch turns ON, and then back door closure motor stops the open
operation.

4.

When automatic back door motor and clutch operate and back door starts the open operation, back door
closure motor operates the reverse operation and starts returning to the neutral operation.
