System Description (cont'd)

TCS Main Control

The ABS/TCS control unit controls the TCS based on signal inputs from the throttle position sensor, engine speed

sensor, shift position sensor, and the wheel sensors. In addition, the ABS/TCS control unit sends an engine retard

request signal to the PCM if necessary. The ABS/TCS control unit uses the modulator unit to control the TCS. The

pressure intensifying control has three modes: pressure intensifying, pressure retaining, and pressure reducing.
