Sliding Roof System -- Fail-Safe Chart |
| SLIDING ROOF OPERATION IN FAIL-SAFE MODE |
Operation switch is shorted to ground
- If a SLIDE OPEN/CLOSE or TILT UP/DOWN switch signal remains on for more than 30 seconds, the signal will be ignored after this 30 second time period elapses.
- If a SLIDE OPEN/CLOSE or TILT UP/DOWN switch signal remains on for more than 30 seconds, the signal will be ignored after this 30 second time period elapses.
Failure of one hall sensor
- When the ECU recognizes a failure of one hall sensor, the AUTO function will be prohibited.
- When the ECU recognizes a failure of one hall sensor, the AUTO function will be prohibited.
Failure of two hall sensors
- The ECU cannot recognize whether the hall sensors are malfunctioning or the motor is stalled. If the motor is operating, the ECU will stop the motor immediately. After stopping motor operation, the ECU will operate normally the next time a switch is pressed.

Simultaneous input
- When both TILT UP and SLIDE OPEN/CLOSE signals are sent, the ECU will ignore the signals and stop operating the sliding roof.
- When both TILT UP and SLIDE OPEN/CLOSE signals are sent, the ECU will ignore the signals and stop operating the sliding roof.
Sliding roof position problem
- If the ECU recognizes a problem with the position of the sliding roof, the ECU will stop the motor (if initialization is being performed, the motor will be allowed to operate). After stopping the motor, the ECU will clear its stored position data. As a result of clearing the stored position data, initialization will be required. Refer to Initialization for details.

After stopping the motor, the ECU will clear its stored position data. As a result of clearing the stored position data, initialization will be required. Refer to Initialization for details.
Exceeding maximum allowable motor runtime
- The ECU monitors the motor operation time to protect the motor. If the total motor operation time exceeds 120 seconds during SLIDE OPEN or TILT UP operation, the ECU will stop the motor. After the motor is stopped, the motor operation will be prohibited until 100 seconds have passed.

Relay error
- If the ECU recognizes this error, the ECU will stop the motor immediately.
- If the ECU recognizes this error, the ECU will stop the motor immediately.
Failure in EEPROM parameters
- If the ECU recognizes this failure, the ECU will stop the motor immediately. After the motor is stopped, all functions will be prohibited.
- If the ECU recognizes this failure, the ECU will stop the motor immediately. After the motor is stopped, all functions will be prohibited.
Supply voltage out of range (9 to 15 V)
- If the ECU recognizes that the supply voltage is not within the specified range, the ECU will stop the motor. However, while a jam protection reverse operation is being performed, the motor will not be stopped until the reverse operation is completed. After the motor is stopped, all functions will be prohibited until the supply voltage returns to normal.
- If the ECU recognizes that the supply voltage is not within the specified range, the ECU will stop the motor. However, while a jam protection reverse operation is being performed, the motor will not be stopped until the reverse operation is completed. After the motor is stopped, all functions will be prohibited until the supply voltage returns to normal.
Strong voltage spike (load dump detected*)
- When the ECU recognizes a strong voltage spike (load dump detected), the ECU will stop the motor. After the motor is stopped, all functions are prohibited during the voltage spike.
- HINT:
- *: A load dump occurs when a large electrical load has been removed from the charging system, causing system voltage to spike.
- When the ECU recognizes a strong voltage spike (load dump detected), the ECU will stop the motor. After the motor is stopped, all functions are prohibited during the voltage spike.
