DTC U0001 Can Communication Malfunction: General Description

Several control units are applied to electronically controlled vehicles. These units perform each control with informations from various sensors. Thus, sharing signal information from sensors is needed, so CAN communication type whose communication speed is high and insensitive to electrical noise by spark generation is adopted to controlling power-train (PCM, ABS, ESP)

As sharing signals of engine speed, APS, gear shifting, torque reduction in ESP. ABS and various modules, active control is performed.
