DTC C1605 Can Hardware Error: General Description

CAN communication is applied just for ESC (Electronic Stability Control) installed in the vehicle for sending requirement data, such as torque reduction, the number of fuel cut cylinders, and TCS control requests, to the Engine ECM & TCU. The Engine ECM performs fuel cut functions according to requests from the ABS ECU and retards ignition timing by torque reduction requests. The TCU maintains current gear positions during ESC control time, by not increasing power which causes a kickdown shift.
