General Information

Component Location





General Description

CAN communication is applied just for FTCSs (Full Traction Control Systems) 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 PCM (ECM & TCM).
The Engine PCM (ECM) performs fuel cut functions according to requests from the ABS ECU and retards ignition timing by torque reduction requests.
The PCM (TCM) maintains current gear positions during TCS control time, by not increasing power which causes a Kickdown shift.

DTC Description

The HECU checks the CAN communication lines for normal TCS control, and sets this code if an ECM message is not received within 500 ms.
The HECU does not detect this code until 2 seconds after the IG KEY is turned to ON.
