摘要： PROBLEM TO BE SOLVED: To enable decision of the functional trouble of an oil temperature sensor situated at an automatic transmission when a signal from the sensor is in an ordinary working temperature region. SOLUTION: An automatic transmission system for a vehicle is provided with an intake air temperature sensor 7 to detect an engine intake air temperature, an air conditioner outside air temperature sensor 10 to detect an outside air temperature, and an oil temperature sensor 9 to detect a temperature of oil to operate an automatic transmission 2. Signals from the sensors 7 and 10 are inputted to a control unit 5 for controlling the automatic transmission, it is diagnosed that the oil temperature sensor 9 is failed when an outside air temperature is compared with an oil temperature to detect it to be lower than the outside air temperature.

摘要： PROBLEM TO BE SOLVED: To make it easy to decide on legitimacy by causing a diagnostic device to quickly display a CVN (Calibration Verification Number). SOLUTION: This controller 1 includes a flash memory 5 made rewritable for storing programs or data, and a CVN computing means for computing CVN values that guarantee the contents thereof. The controller has an EEPROM 6 made rewritable for storing computed CVN storage values. When a determination is made that no rewrites were made on the flash memory 5, the computed CVN storage values stored in the EEPROM 6 are outputted to compute a CVN and the computation result is outputted; when there is a rewrite on the flash memory 5, the computation result is outputted after computation of the CVN is complete.
