General Information

Component Location





General Description

The HECU send requirement data, such as Torque reduction, the number of fuel cut cylinders and ESC control requests, to the Engine PCM (ECM & TCM) through CAN bus line.
The Engine 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 ESC control time, in order not to increase power which causes a Kickdown shift.

DTC Description

The HECU checks the CAN communication lines for normal TCS control and sets this code if CAN BUS OFF status is detected for more than 100ms.
