Pressure Control Solenoid Valve Inspection - Suzuki Liana RH418 Supplementary Service Manual

TCC solenoid valve
• Check that solenoid valve (1) actuate with click sound
when battery voltage is conducted.
• Apply oiler (2) to solenoid valve (1) and give
compression by hands and then check to be sure that
transaxle fluid from oiler does not come out of holes in
solenoid valve when battery voltage is conducted.
• Under the same conditions, release battery voltage
and then make sure that fluid comes out with vigor. If
check result is not as described, replace shift solenoid
valve.

Pressure Control Solenoid Valve Inspection

Resistance Check
Measure resistance between pressure control solenoid
valve (1) terminals.
Pressure control solenoid valve resistance
Standard: 3.3 – 3.7 Ω (at 20 °C (68 °F))

Automatic Transmission/Transaxle:
1) Connect pressure control solenoid valve (1) with
regulated DC power supply (2) as shown in the
figure.
2) Turn regulated DC power supply switch ON and
increase voltage of power supply keeping current
within 1.0 A.
3) Check for gradual movement of valve (3) in the
direction of arrow "A" as voltage is increased.
4) Check movement of valve (3) in the direction of
arrow "B" as voltage is decreased.
5) Turn power supply switch OFF.
CAUTION
!
Do not pass current 1.0 A or more, or
pressure control solenoid is burned out.
