solenoid (SLT), then the TCU will shut off the current
to the line pressure control solenoid. (The line
pressure is maximized, If the line pressure control
solenoid current is shut off when any abnormality of
the SLT other than valve stuck occurs.)
4. Lock-up control solenoid (SLU)
The lock-up control solenoid (SLU) is installed on the
sic
front valve body. It linearly controls lock-up clutch
hydraulic pressure based on engine rpm, throttle
opening degree signals, input speed sensor (NIN)
signals, and output speed sensor (SP) signals. This
results in control of lock-up. As a fail-safe function, if
any abnormality occurs in the lock-up control
solenoid (SLU), then the TCU will shut off the current
SENAT7100D to the solenoid.
Function Of Each Solenoid Specification Of Each Solenoid
1. 3-way solenoids (S1,S2) 3-way Solenoid (S1,S2)
oe
The 3-way solenoids (S1, S2) are installed on the
front valve body. The solenoids turn ON and OFF in
response to signals output from the TCU. According
to the ON or OFF status of S1 or S2, the 1st gear
engine brake operates or a gear shift occurs. As a
fail-safe function, if any shift solenoid abnormality
occurs, the TCU will disable the current to the
solenoids.
2. Shift control solenoids (SLC1, SLC2, SLC3, SLB1)
The shift control solenoids (SLC1, SLC2, SLC3,
lec
SLB1) are installed on the front valve body. The
solenoids linearly control hydraulic pressure in
response to signals output from the TCU. Through
this, it controls hydraulic pressure to the clutches
(C1, C2, C3) and brake (B1) for smooth shifting.
According to each shift control solenoid, the transaxle
shifts from 1st gear into 6th gear and vice versa. As a
fail-safe function, if any shift control solenoid occurs,
the TCU will shut off the current to the solenoids.
3. Line pressure control solenoid (SLT) SENAT7101L
The line pressure control solenoid (SLT) is installed
on the front valve body. In accordance with the value
