FAIL-SAFE CONTROL BY POWER WINDOW MOTOR
Power window motor switches power window operation to fail-safe control when malfunction is detected.
| Detected item | Judgment condition | Fail-safe operation | Recovery condition |
|---|---|---|---|
| Non-Initialized condition | When the motor integrated CPU detect door glass position non-initialized condition | Auto UP operation (Anti-pinch) is forbidden | Initialization completed |
| Thermal protection | When the motor integrated CPU first detects thermal protection. | DOWN operation is forbidden | After cooling, a certain amount of time has passed in the power switch ON state. (Reference values: approximately 30 to 90 seconds, the elapsed time will be changed depending on how the temperature drops.) |
| When the motor integrated CPU detects thermal protection again when UP operated from the above state. | Operation is forbidden (UP and DOWN is forbidden) | ||
| Consecutive reverse operation malfunction | When the motor integrated CPU has detected consecutively 3 times the reverse operation | Auto UP operation (Anti-pinch) is forbidden | Approximately 10 seconds passed or the motor integrated CPU detect door glass fully close position |
