DTC U0001-88: High Speed CAN Bus-Off: General Description

CAN communication is a communication system for electric control units (engine, transmission, AWD ECU, ABS/ESP...) through which they exchange information through 2 lines-CAN Low and High. The ATC AWD system distributes the optimal operational torque to the front and rear wheels according to the CAN signals (engine torque, gear change, acceleration pedal sensor, wheel speed, brake control, etc.) it receives from other control units.
