POWER RETRACTABLE HARDTOP CONTROL MODULE FUNCTION

id091600101400

• Controls the power retractable hardtop control module, roof motor, and the deck panel motor based on the signals from each switch.
• A fail-safe function has been adopted which stops the operation if an abnormal signal is detected from any part during power retractable hardtop operation.
• A self-diagnostic function has been adopted which can verify the malfunctioning area.

Fail-safe Function

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

Item | Detection Condition | Action after malfunction detected | Recovery condition
--- | --- | --- | ---
Power supply voltage error | Power supply voltage is 7.5 V or less, or 17.5 V or more. | • Power retractable hardtop not operated → Inhibits power retractable hardtop operation • Power retractable hardtop operating → Stops power retractable hardtop operation | Power supply voltage is between 8.5 to 16.5 V.
Roof/deck panel motor hall sensor power supply voltage error | Sensor power supply voltage is 5 V or less. | Stops roof/deck panel motor operation | The ignition switch is turned from the ON position in the following order. • OFF → ON
Roof/deck panel motor hall sensor malfunction | Roof/deck panel motor hall sensor pulse signal cannot be detected. | Temporarily stops the operation, however, the operation can be performed by turning on the power retractable hardtop switch again. | Pulse signal detected
Door glass open notification signal error | Door glass open notification signal cannot be detected. | • If the signal is detected during the power retractable hardtop close operation, inhibits the operation after the power retractable hardtop is fully closed. (Only deck panel can operate.) • If the signal is detected during the power retractable hardtop open operation, the open operation continues and after the operation finishes, the close operation can be performed only once. Inhibits the operation after the power retractable hardtop is fully closed. (Only deck panel can operate.) | Door glass open notification signal can be detected.
Open notification signal is received continuously for 30 s or more. | • If the signal is detected with the power retractable hardtop fully closed and not operating, inhibits the operation. • If the signal is detected with the power retractable hardtop fully open and not operating, the power retractable hardtop close operation can be performed only once. Inhibits the operation after the power retractable hardtop is fully closed. | Continuous reception of the open notification signal stops temporarily.
Roof/deck panel motor malfunction | Supply voltage to the motor is lowered. | Stops roof/deck panel motor operation | The ignition switch is turned from the ON position in the following order. • OFF → ON
Roof panel motor (Left and right position combination) | Difference in pulse count number between left and right is at a certain level or more. | Stops roof panel motor operation | Power retractable hardtop switch is operated again. However, if detected three times or more, the ignition switch is turned from the ON position in the following order. • OFF → ON
Deck panel motor (Left and right position combination) | Difference in pulse count number between left and right is at a certain level or more. | Stops deck panel motor operation | Power retractable hardtop switch is operated again. However, if detected three times or more, the ignition switch is turned from the ON position in the following order. • OFF → ON
Power retractable hardtop/deck panel limit switch malfunction | The power retractable hardtop/deck panel limit switch is malfunctioning. | Inhibits power retractable hardtop operation. | Normal logic is detected.
Top lock switch malfunction | Top lock switch on is detected with the power retractable hardtop open. | Close operation can be performed only once. Inhibits the operation after the power retractable hardtop is fully closed. | Top lock switch off is detected.
Top lock switch off is detected with the power retractable hardtop closed and vehicle speed detected. | None | Vehicle speed 0 km/h is detected.
Power retractable hardtop switch malfunction | Switch input is 1 V or less. | Inhibits power retractable hardtop operation. | Normal input voltage is recovered.
Switch on signal is detected for 30 s or more after IG-ON. | Inhibits power retractable hardtop operation. | Power retractable hardtop switch off signal is detected.
Power retractable hardtop open and close on signals are detected simultaneously for 30 s or more. | Inhibits power retractable hardtop operation. | Power retractable hardtop switch off signal is detected.
Communication error | CAN system of the power retractable hardtop control module is malfunctioning. | Inhibits power retractable hardtop operation. | Normal communication is recovered.
CAN communication error between PCM and power retractable hardtop control module | Inhibits power retractable hardtop operation. | Normal communication is recovered.
CAN communication error between TCM and power retractable hardtop control module | Inhibits power retractable hardtop operation. | Normal communication is recovered.
Vehicle speed signal error | Inhibits power retractable hardtop operation. | Normal communication is recovered.

Buzzer Operation Function

• Sends beep signals to the instrument cluster before and after the power retractable hardtop system operation, when the operation is refused, and during an operation warning. (See POWER RETRACTABLE HARDTOP WARNING ALARM CONSTRUCTION/OPERATION.)

Power Retractable Hardtop Indicator Light Control

• Sends illumination or flash signal to the power retractable hardtop indicator light in the following pattern depending on the power retractable hardtop status.

Illumination pattern | Illumination condition | Lights off condition
--- | --- | ---
Power retractable hardtop operating |  | Power retractable hardtop operation is continued. | • Open operation is finished. • Close operation is finished.
Power retractable hardtop half-open and not operating |  | • Power retractable hardtop is fully opened and the top lock is unlocked. (Top lock switch is OFF.) • Power retractable hardtop switch is turned off during power retractable hardtop operation and the operation is temporarily stopped. | • Open operation is finished. • Close operation is finished.
Power retractable hardtop system malfunctioning |  | DTC is detected or recorded.(The power retractable hardtop indicator light does not illuminate depending on the DTC.)(The power retractable hardtop indicator light does not illuminate depending on the DTC.)(See ON-BOAD DIAGNOSTIC PID DATE MONITOR FUNCTION.) | • Malfunction is repaired or the DTC is cleared.
