General Information

ESP (CTC)
C1616 CAN Communication Bus Off - General Information

Component Location





General Description

The HECU sends the request messages, such as torque reduction and fuel cut, to the ECM and TCM through CAN bus line for TCS control. The Engine ECM carries out the fuel-cut logic according to the request messages from the HECU and it also retards an ignition timing by torque reduction requests. The TCM maintains current gear position during TCS control in order to prevent an acceleration force from rising by a kickdown shift.

DTC Description

The HECU monitors CAN communication line and if the CAN BUS OFF happens more than 10 times, this DTC is set.
