TCS system
The TCS engine control system manages the engine output torque on slippery roads.
The TCS system detects the vehicle skidding conditions according to the speed of each wheel and reduces the
output torque by means of the I X H O L J Q L W L R Q F X W R I I D Q G W K H F K R N L Q J of the DBW throttle opening till the proper
traction control is restored.
The TCS system uses the same signals from the phonic wheels, also used by the ABS system, and reduces the torque through the injection system.
