WHEEL PRESSURE MODULATION

Loading situation	Control duration	Pressure applied by braking while an ESC cycle is in progress	Controlled FA pressure, one wheel only	Controlled RA pressure, one wheel only
A	1.4 s	0 MPa	7.0 ~ 8.5	0.7 ~ 1.3
		5.0 MPa	10.0 ~ 12.0	5.5 ~ 6.5
		10.0 MPa	10.0 ~ 12.0	5.5 ~ 6.5
B	1.4 s	0 MPa	2.5 ~ 3.5	uncontrolled
B	1.4 s	5.0 MPa	7.5 ~ 8.5	uncontrolled
D	1.4 s	0 MPa	uncontrolled	3.0 ~ 4.0
D	1.4 s	5.0 MPa	uncontrolled	5.5 ~ 6.5

The ESC control cycles may be inserted into the ABS/TCS load collective at any point as long as the duty cycle for the electric motor does not exceed 20%.
