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”.

4. Set “ENGINE BRAKE LEVEL” by touching “UP” or “DOWN”.
5. Turn ignition switch OFF, wait at least 5 seconds and then turn
ignition switch ON.
6. Engine brake level set is completed.
CAUTION:
Mode of “+1” “0” “-1” “-2” “OFF” can be selected by press-
ing the “UP” “DOWN” on CONSULT-II screen. However, do not select mode other than “0” and
“OFF”. If the “+1” or “-1” or “-2” is selected, that might cause the irregular driveability.
Check CVT Fluid Deterioration Date

2. Touch “CONFORM CVTF DETERIORTN”.
3. Check “CVTF DETERIORATION DATE”“ENGINE BRAKE LEVEL”
0: Initial set value (Engine brake level control is
activated)
OFF: Engine brake level control is deactivated.

cuit

ary pressure sensor) is too high or too low while drivingP0840CVT-118

When the power supply to the TCM is cut OFF, for example
because the battery is removed, and the self-diagnosis memory
function stops

This is not a malfunction message (Whenever shutting OFF a

(control unit) is malfunctioning

There is a great difference between the vehicle speed signal from
the ABS actuator and the electric unit (control unit), and the vehi-
cle speed sensor signalP1722CVT-141
