These DTCs are output when an IC overheat malfunction or an overcurrent malfunction is detected in the intake side camshaft timing control motor. The camshaft timing control motor is equipped with a self diagnostic function, which is used to output diagnosis signals (VTM) to the ECM. If the ECM receives a motor driver interior malfunction signal, a DTC is output immediately (1 trip detection logic).
