DTC C1605 CAN HARDWARE ERROR

COMPONENT LOCATION

Refer to DTC C1235. C1235

GENERAL DESCRIPTION

The HECU send requirement data, such as Torque reduction, the number of fuel cut cylinders, and TCS control requests, to the PCM(ECM & TCM) through CAN bus line. The PCM(ECM) performs fuel cut functions according to requests from the HECU and retards ignition timing by torque reduction requests. The PCM(TCM) maintains current gear positions during TCS control time, in order not to increase power which causes a Kickdown shift.

DTC DESCRIPTION

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