Trouble recovery can be roughly divided into 2 types. Depending on the actual machine, an additional 1 cycle is sometimes necessary after the cycle below to delete the DTC displayed on the monitor screen. *1 In the cycle in which the DTC was detected, even if the machine recovers to normal (including intermittent problems), the DTC does not disappear from the monitor screen and backup mode does not recover to normal mode. After the key is switched OFF, when the engine is restarted, the trouble judgment is made and if it is judged that the status is normal, • Generally, the trouble judgment ends immediately and the DTC disappears and operation recovers to normal if it is judged that the status is normal. • Trouble judgment takes 3 - 10 min. for a temperature sensor, and the DTC disappears and operation recovers to normal if it is judged that the status is normal.
