Road TestBCS001GK
DESCRIPTION

The purpose of the test is to determine overall performance of
CVT and analyze causes of problems.

The road test consists of the following three parts:
1. “Check Before Engine Is Started” CVT-37
.
2. “Check at Idle” CVT-37
.
3. “Cruise Test” CVT-38
.

Before road test, familiarize yourself with all test procedures and
items to check.

Perform tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.
CONSULT-II OPERATION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.

Using CONSULT-II, perform a cruise test and record the result.

Print the result and ensure that shifts and lock-ups take place as per Shift Schedule.
1. Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.
2. Touch “MAIN SIGNALS” to set recording condition.
3. See “Numerical Display”, “Barchart Display” or “Line Graph Dis-
play”.
4. Touch “START”.

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionBCS001IH

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 2/8) 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.

On Board Diagnosis LogicBCS001IJ
Diagnostic trouble code “P0740 TCC SOLENOID/CIRC” with CONSULT-II is detected under the following con-
