SEAT: FRONT POWER SEAT CONTROL SYSTEM: INITIALIZATION

1. INITIALIZE SLIDING FUNCTION AND RECLINING FUNCTION OF POSITION CONTROL ECU

(a) Perform initialization of the position control ECU when any of the following conditions are met. The initialization sets the absolute position of the power seat's sliding and reclining functions.

* The battery is disconnected.

* The D/C CUT fuse is replaced.

* The position control ECU is replaced.

* The power seat is removed from the vehicle.

HINT
Controlling the power seat's sliding and reclining functions together prevents the power seat from interfering with the rear seat during the power seat's sliding or reclining operation.

(b) Initialize the sliding function and reclining function of the position control ECU.

(1) Use the sliding or reclining function with the front power seat switch to move the power seat to the foremost position (lock position). A buzzer sounds for 0.1 seconds.

(2) Use another function (sliding or reclining) which was not used in the previous step to move the front power seat to the foremost position (lock position). A buzzer sounds for 0.5 seconds.

(3) The position control ECU's initialization is completed.

NOTICE:
* If the initialization is not completed, the power seat's sliding and reclining functions cannot be controlled together.
* If the initialization is not completed, a buzzer sounds at 0.45 second intervals while the power seat is sliding backwards or reclining.
* If the initialization is not completed, the position control ECU will not memorize any seat position.
2. CANCEL INITIALIZATION OF POSITION CONTROL ECU

HINT
When the linked control of the power seat's sliding and reclining functions does not work properly, the seat's operational area is restricted. In this case, cancel the initialization of the position control ECU so that the sliding and reclining functions can be operated independently.

(a) Turn the ignition switch to ON.

(b) Press the front power seat switch (front vertical switch) downward 3 times.

HINT
Perform each switch operation within 10 seconds of the previous operation.

(c) Within 10 seconds of the above operation, begin the following operation: perform the rearward reclining operation and upward lifter operation simultaneously for 10 seconds or more (a buzzer sounds for 0.5 seconds). This will clear the memory and cancel the initialization.

HINT
If the seat's operational area is still restricted after the cancellation, the motor is malfunctioning.

NOTICE:
After the cancellation, a buzzer sounds at 0.45 second intervals while the power seat is sliding backwards or reclining. If the initialization is performed again, the buzzer stops.
