DescriptionUCS00603
TCM selects the gear ratio using the engine load (throttle position), the primary pulley revolution speed, and
the secondary pulley revolution speed as input signal. Then it changes the operating pressure of the primary
pulley and the secondary pulley and changes the groove width of the pulley.
CONSULT-II Reference ValueUCS00604

On Board Diagnosis LogicUCS00605

This is not an OBD-II self-diagnostic item.

TCM calculates the actual gear ratio with input speed sensor (primary speed sensor) and output speed
sensor (secondary speed sensor).

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionUCS00609

The torque converter clutch solenoid valve is included in the control valve assembly.

The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the
vehicle speed and accelerator pedal position sensors. Lock-up piston operation will then be controlled.

Lock-up operation, however, is prohibited when CVT fluid temperature is too low.

When the accelerator pedal is depressed (less than 2.0/8) 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.
CONSULT-II Reference ValueUCS0060A
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS0060B

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0740 TCC SOLENOID/CIRC” with CONSULT-II is detected under the following
conditions.
–TCM detects an improper voltage drop when it tries to operate the solenoid valve.
