C1611

DTC C1611 EMS TIME - OUT FAILURE (only System with TCS

DESCRIPTION
HECU will compare signals from front (driving) and rear wheel speed sensors to detect driving wheels slip.
Upon detecting driving wheels slip, HECU will perform TCS control.

The HECU will transmit engine torque reduction request, fuel cut cylinder number, and TCS control request signals in accordance with slip level to engine ECM and TCM through BUS line which will provide CAN communication for TCS control.

Engine ECM will perform fuel cut as requested by HECU and retard ignition timing as per engine torque reduction request signal.

TCM will hold shift position by TCS control time according to TCS operation signal.

Then enhanced acceleration by kick - down will not occur.





DTC DETECTING CONDITION

FAIL-SAFE FUNCTION
Inhibit the TCS control and allow the ABS/EBD control.
