Shift solenoid valves A and B are turned ON or OFF by the TCM in
response to signals sent from the PNP switch, vehicle speed and
throttle position sensors. Gears will then be shifted to the optimum
position.

TORQUE CONVERTER CLUTCH SOLENOID VALVE

TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionECS004U4
The torque converter clutch solenoid valve is activated, with the gear
in “D
4 ”, by the TCM in response to signals sent from the vehicle
speed and throttle position sensors. Lock-up piston operation will
then be controlled.
Lock-up operation, however, is prohibited when A/T fluid tempera-
ture is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up
condition, the engine speed should not change abruptly. If there is a
big jump in engine speed, there is no lock-up.

LINE PRESSURE SOLENOID VALVEPFP:31940
DescriptionECS004UF
The line pressure solenoid valve regulates the oil pump discharge
pressure to suit the driving condition in response to a signal sent
from the TCM.
The line pressure duty cycle value is not consistent when the
closed throttle position switch is ON. To confirm the line pres-
sure duty cycle at low pressure, the accelerator (throttle)
should be open until the closed throttle position switch is OFF.
CONSULT-II Reference ValueECS00CT5
Remarks: Specification data are reference values.
NOTE:
The line pressure duty cycle value is not consistent when the closed throttle position switch is “ON”. To confirm the line pressure duty
cycle at low pressure, the accelerator (throttle) should be open until the closed throttle position switch is “OFF”.

MAIN POWER SUPPLY AND GROUND CIRCUITPFP:00100
DescriptionECS00CS1
When the power supply to the TCM is cut OFF, for example because the battery is removed, and the self-diag-
nostics memory function stops, malfunction is detected.
On Board Diagnosis LogicECS00CS2

Diagnostic trouble code “INITIAL START” with CONSULT-II is detected when TCM dose not receive the
voltage signal from the battery power supply.

This is not a malfunction message. (Whenever shutting “OFF” a power supply to the TCM, this message
appears on the screen.)
Possible CauseECS00CS3
