Electronic Stability Control
C1605 CAN Hardware error - General Information

Component Location





General Description

The HECU sends requirement data, such as torque reduction, the number of fuel cut cylinders, and the ESC control request, to the PCM(ECM & TCM) through CAN bus line. The PCM(ECM) performs the fuel cut function according to a request signal from the HECU and then retards an ignition timing. The PCM(TCM) maintains current gear position during the ESC control period in order not to increase power which causes a Kickdown shift.

DTC Description

The HECU checks the CAN RAM for normal TCS control, and sets this code if a CAN RAM malfunction is detected.
