Traction Control System
C1611 EMS Time-out failure - 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 ECM & TCM. The Engine ECM performs fuel cut functions according to requests from the ABS ECU and retards ignition timing by torque reduction requests. The 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 communcation lines for normal TCS control, and sets this code if an ECM message is not received within 500ms. The HECU does not detect this code until 2 seconds after the IG KEY is turned to ON.
