CONSULT-III Function (TRANSMISSION)INFOID:0000000003848944
FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
WORK SUPPORT MODE
Display Item List
Engine Brake Adjustment
CAUTION:
Mode of “+1”“0”“−1”“−2”“OFF” can be selected by touching “UP”or “DOWN” on CONSULT-III screen.
However, do not select a mode other than “0” and “OFF”. Selecting “+1” or “−1” or “–2” may cause
irregular driveability.
Check CVT Fluid Deterioration Date
CAUTION:
Touch “CLEAR” after changing CVT fluid, and then erase “CVTF DETERIORATION DATE”.
SELF-DIAGNOSTIC RESULT MODE
Display Items List
Refer to TM-121, "DTC Index".
DATA MONITOR MODE
Display Items List
Diagnostic test mode Function
Work Support This mode enables a technician to adjust some devices faster and more accurately.
Self-Diagnostic Results Retrieve DTC from ECU and display diagnostic items.
Data Monitor Monitor the input/output signal of the control unit in real time.
CAN Diagnosis This mode displays a network diagnosis result about CAN by a diagram.
CAN Diagnostic Support Monitor It monitors the status of CAN communication.
Function TestThis mode can show results of self-diagnosis of ECU with either “OK” or “NG”. For en-
gine, more practical tests regarding sensors/switches and/or actuators are available.
ECU Identification Display the ECU identification number (part number etc.) of the selected system.
Special Function Other results or histories, etc. that are recorded in ECU are displayed.
Item name Description
ENGINE BRAKE ADJ. The engine brake level setting can be canceled.
CONFORM CVTF DETERIORTN The CVT fluid deterioration level can be checked.
“ENGINE BRAKE LEVEL”
0 : Initial set value (Engine brake level control is activated)
OFF : Engine brake level control is deactivated.
“CVTF DETERIORATION DATE”
More than 210000 : It is necessary to change CVT fluid.
Less than 210000 : It is not necessary to change CVT fluid.
