DTC U0401: Engine malfunction detected Mitsubishi Lancer IX facelift

CAUTION

If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be set. Prior to this diagnosis, diagnose the CAN bus lines. Whenever the ECU is replaced, ensure that the CAN bus lines are normal. If diagnostic trouble code U0401 is set in ASC-ECU, always diagnose CAN bus lines. If there is any fault in the CAN bus lines, an incorrect DTC may be set. When the hydraulic unit (integrated with ASC-ECU) is replaced, after turning the ignition switch ON and OFF (vehicle information from ETACS-ECU is registered), always perform the calibration of steering wheel sensor, G and yaw rate sensor, brake fluid pressure sensor, cut valve, and inlet valve.(Refer to IN THE EVENT OF A DISCHARGED BATTERY , STEERING WHEEL SENSOR CALIBRATION , MASTER CYLINDER BRAKE FLUID PRESSURE SENSOR CALIBRATION , and CALIBRATION OF CUT VALVE AND INLET VALVE .)
