Full Traction Control System (FTCS)
- The ABS control module (HECU) controls TCS control too.
- 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 TCS control will include brake TCS (BTCS) control.
- 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.
