On-Vehicle Inspection
ON-VEHICLE INSPECTION1. OPERATING CONDITION
In case that the following conditions are satisfied with "and"-condition, this retractable hardtop system will operate.
a. Ignition switch is ON
b. Vehicle speed is less than 5 km/h (3 mph)
c. Luggage opener main switch is ON
d. Tonneau cover switch is ON when roof opening only
e. Luggage compartment door lock motor and detection switch is "ON"
(When the switch failure, operation is inhibited. When the communication failure on BEAN, this condition is omitted)
2. PACKAGE TRAY TRIM LINKED CONTROL OPERATION
a. The package tray trim is operated when the roof reaches the specified position detected by the 3 limit switches (Roof position No. 1, No. 2 and No. 3).
3. PACKAGE TRAY AWAIT CONTROL
a. Open control:
If the roof is in the middle (position 2) and the package tray trim is not fully open, it returns to the middle (position 1) and waits for the operation of the package tray trim.
b. Close control:
If the roof is in the middle (position 2) and the package tray trim is not fully open, it returns to the middle (position 1) and waits for the operation of the package tray trim. (Switching position)
4. DOOR WINDOW LINKED CONTROL
a. While opening and closing the retractable hardtop, if a door window is closed, it will go down before the retractable hardtop starts operating.
b. When door windows open 1/3 or more, the retractable hardtop system starts to operate.
c. Power window switch is operated manually while the door window linked control, retractable hardtop operation is continued if door window is opened 1/3 or more.
5. OTHER CONTROL MOTOR SPEED CONTROL
a. Speed control
The roof motors (LH/RH) and the luggage motors (LH/RH) control speed with current controlled by duty cycle (PWM-Pulse Width Modulator). These motors provide motor pulse count feedback to detect the motor rotation position and speed, resulting in crosswise synchronous control and a slow start/slow stop control. (Motor control)
b. Slow start/Slow stop control
When starting the retractable hardtop operation, the operation of the roof is started at low speed and the speed is increased gradually.
In the low speed range when the roof is just before fully closed or fully opened, opening and closing operation speed is gradually decreased to low speed.
When the roof is opening and closing from the low speed range, the roof keeps the low speed retention operation.
The recognition of the low speed range is judged by the motor pulse count. When the motor pulse signal of the roof is abnormal, the roof always keeps the low speed retention operation (Switching position).
c. Synchronization control
Synchronization control operates when the roof drive motor LH/RH drives the roof and the luggage door drive motor LH/RH drives the luggage door.
By memorizing the motor position when starting the retractable hardtop operation as an initial position, synchronization control counts the number of motor pulses in order to make the right and left motors run with the same speed and detect the motor rotation position (roof position). Also synchronization control controls to make the speed per unit time equal.
d. Door window manual operation control
When the following operation is done, the door window is closed automatically after completion of retractable hardtop operation both opening/closing;
When the retractable hardtop control switch is pressed and held continuously, the retractable hardtop fully opens and fully closes. When the control switch is pressed again, the door windows close automatically.
The indicator lamp and warning buzzer operate as described in the table is as given.
e. Fail-safe
If abnormality of motor and limit switch occurs, the system will operate to prevent vehicle breakdown or driving with a half open roof as much as possible.
6. CHECK AIR CONDITIONING ASSEMBLY
a. Remove the A/C control but do not disconnect the connectors.
b. Turn the ignition switch ON.
c. Measure the voltage of the A/C control.
If the result is not as specified, replace the A/C control assembly with the connectors still connected.
