VFS CONTROL PRESSURE

VFS CONTROL PRESSURE:

- Test condition:
Ps Supply Pressure (Ps = 7.1 ± 0.3 kgf/cm2)kgf
Pc Control Pressure
Pex Exhaust Pressure (Atmosphere pressure)
^ ATF: DIAMOND ATF SP-III
ATF temperature: 30 ± 3°C (86°F)
Coil resistance: 4.35 ± 359
Dither Frequency: 600 ± 20 Hz
In case of VFS solenoid valve, the relation between Duty and oil pressure can't be expressed.

SOLENOID VALVES SCHEDULE

SOLENOID VALVES SCHEDULE:

*: Reference value. (DCC solenoid valve will be ON when the operating condition is satisfied).

A/T Control Relay





The control relay supplies power to the solenoid valves. As soon as the A/T control relay is ON, the battery voltage is directly supplied to solenoid valves and each solenoid valve is operated when the TCM grounds the opposite terminal. - (-) Control at fail safe condition, the power is cut causing 3 gear hold.
