On-Vehicle Inspection
CONVERTIBLE: RETRACTABLE HARDTOP SYSTEM: ON-VEHICLE INSPECTION
1. OPERATING CONDITION
The retractable hardtop system operates when the following conditions are met.
(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 (Only when roof is open)
(e) Luggage courtesy switch is ON
(When the switch is malfunctioning, the retractable hardtop system operation is stopped. When there is a communication failure through the BEAN line, the condition of the switch is omitted from this operation condition list.)
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, the roof 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, the roof 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 the door windows open 1/3 or more, the retractable hardtop system starts to operate.
(c) If the power window switch is 1/3 open and the window is further opened manually, the retractable hardtop operation is not affected.
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 the 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.
* 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 retractable hardtop control switch is pulled and held, the retractable hardtop fully closes. If the switch is not released, the door windows close automatically after the retractable hardtop closing operation is complete. If the switch is released, the door windows close automatically when the control switch is pulled again.
(e) Indicator / Buzzer
The indicator light and warning buzzer operate as described in the table below.
HINT
*: The warning will occur when driving with a half open roof only when the vehicle speed is above 6 km/h (3.8 mph).
(f) 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 Removal.
(b) Turn the ignition switch ON.
(c) Measure the voltage of the A/C control.
Standard resistance:
* If the result is not as specified, replace the A/C control.
