Operation

Electric open/close control function

•  For details on the electric open/close function, refer to the [ELECTRIC OPEN/CLOSE CONTROL FUNCTION] for the retractable hardtop. (See RETRACTABLE HARDTOP.)

Operation condition detection function

•  The retractable hardtop control module detects the motor rotation speed and rotation direction based on the pulse from each motor.

Fail-safe function

•  The retractable hardtop control module monitors each input/output part, and if a malfunction is detected, it performs the following actions.

Item	Detection Condition	Action after malfunction detected	Recovery condition
Power supply voltage malfunction	Power supply voltage is 7.5 V or less, or 17.5 V or more	•  Retractable hardtop is not operated ―  Inhibits retractable hardtop operation •  Retractable hardtop is operating ―  Stops retractable hardtop operation	Power supply voltage is 8.5 or more or 16.5 V or less
Hall effect switch power supply voltage malfunction	Hall effect switch power supply voltage is 5 V or less	Stops motor operation	Ignition is switched from ON in the following order •  OFF to ON
Hall effect switch malfunction	Pulse signal from Hall effect switch cannot be detected	Stops motor operation Note •  The motor can be operated by turning the retractable hardtop switch on again.	Pulse signal is demodulated or ignition is switched from OFF to ON.
Door glass open completion signal error	Door glass open completion signal cannot be received	•  If the condition in which a door glass open completion signal cannot be received is detected while the retractable hardtop is closing, the operation is inhibited after the retractable hardtop is fully closed (only rear roof can operate). •  If the condition in which a door glass open completion signal cannot be received is detected while the retractable hardtop is opening, the open operation continues and after the operation finishes, the close operation can be performed only once. Inhibits the operation after the retractable hardtop is fully closed (only rear roof can operate).	Door glass open completion signal is received
	Open completion signal is received continuously for 30 s or more	•  If the retractable hardtop is not operating and the retractable hardtop is fully closed, inhibits the retractable hardtop operation. •  If the retractable hardtop is not operating and the retractable hardtop is fully opened, the close operation can be performed only once. Inhibits the operation after the retractable hardtop is fully closed.	Continuous reception of open notification signal stops temporarily
Power window system initial setting not performed	Power window system initial setting not performed	•  If power window system initial setting non-implementation is detected with the retractable hardtop closed, the open operation and close operation can be performed only once for each. Inhibits the operation after the retractable hardtop is fully closed (only rear roof can operate). •  If a non-implementation of the power window system initial setting is detected with the retractable hardtop opened, the close operation can be performed only once. Inhibits the operation after the retractable hardtop is fully closed (only rear roof can operate).	Power window system initial setting is performed
Front/rear roof link motor malfunction	Supply voltage to the motor is lowered	Stops motor operation	Ignition is switched from ON in the following order •  OFF to ON
Front roof link motor (Left and right position combination)	Difference in pulse count number between left and right is at certain level or more	Stops motor operation	The retractable hardtop switch is operated again. However, if the difference in pulse count number between the left and right is detected to be at a certain level or more three times, the ignition can only be switched from ON in the order indicated below. •  OFF to ON
Rear roof link motor (Left and right position combination)	Difference in pulse count number between left and right is at certain level or more	Stops motor operation	The retractable hardtop switch is operated again. However, if the difference in pulse count number between the left and right is detected to be at a certain level or more three times, the ignition can only be switched from ON in the order indicated below. •  OFF to ON
Front/rear roof link limit switch malfunction	Front/rear roof link limit switch malfunction	Stops retractable hardtop operation	Normal logic is detected
Top lock switch malfunction	Top lock switch ON is detected with retractable hardtop open	The retractable hardtop close operation can be performed only once. Inhibits the operation after the retractable hardtop is fully closed.	Top lock switch off is detected
	Top lock switch OFF is detected with retractable hardtop closed and vehicle speed	—	Vehicle speed 10km/h is detected
Retractable hardtop switch malfunction	Switch input is 1 V or less	Stops retractable hardtop operation	Normal input voltage is recovered
	Switch ON signal is detected for 30 s or more after ignition is switched ON	Stops retractable hardtop operation	Retractable hardtop switch OFF signal is detected
	Retractable hardtop open/close signals are detected simultaneously for 30 s or more	Stops retractable hardtop operation	Retractable hardtop switch OFF signal is detected
Communication error	Retractable hardtop control module CAN system malfunction	Stops retractable hardtop operation	Normal communication is restored
	CAN communication error between PCM and retractable hardtop control module	Stops retractable hardtop operation	Normal communication is restored
	CAN communication error between TCM and retractable hardtop control module	Stops retractable hardtop operation	Normal communication is restored
	Vehicle speed signal error	Stops retractable hardtop operation	Normal communication is restored
