Component Location
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(TCM, ECM, CLUSTER,VDC,4WD,EAS,SAS, EPS)
CAN communication consists of CAN BUS HIGH, CAN BUS LOW and two 120? resistances in circuit.
DTC Description
TCM set this code If not receive CAN message form ACC.(MIL OFF)
