Control system

•

Communication between the ABS/TCS module and the PCM is carried out through a
high-speed CAN-BUS (Controller Area Network-BUS).

Data sent

–

Torque reduction request

–

Wheel speeds of all four wheels

Data received

–

Engine speed

–

Engine torque

–

Throttle valve opening angle

–

Vehicle speed

On-board diagnostic system

•

The on-board diagnostic system for the RF-T TCS is basically the same as that for the L3
engine system except for the following:

–

Diagnostic procedures for DTCs C1117,C1119, U0100, U0073 are different than
