摘要
An ECU executes a program including the steps of determining that a change speed solenoid is abnormal when a target speed ratio falls within a predetermined range, an upshift is recognized and the change speed solenoid is abnormal; determining that the change speed solenoid is normal when the change speed solenoid is not abnormal; determining that a belt pinch pressure solenoid is abnormal when the target speed ratio is substantially equal to a speed ratio γmin on a maximum speed-increase side and the target speed ratio is not substantially equal to an actual speed ratio; and determining that the belt pinch pressure solenoid is normal when the target speed ratio is substantially equal to the actual speed ratio.
