TROUBLE DIAGNOSIS
Data are reference value and are measured between each terminal and ground.
CONSULT-III Function (TRANSMISSION)INFOID:0000000001327163
CONSULT-III can display each diagnostic item us ing the diagnostic test models shown following.
FUNCTION
CONSULT-III REFERENCE VALUE
NOTICE:
1. The CONSULT-III electrically displays shift timi ng and lock-up timing (that is, operation timing of each
solenoid).
Check for time difference between actual shift timi ng and the CONSULT-III display. If the difference is
noticeable, mechanical parts (except solenoids, sens ors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) display ed on CONSULT-III and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
- Actual shift schedule has more or less tolerance or allowance,
- Shift schedule indicated in Service Manual refers to the point where shifts start, and
- Gear position displayed on CONSULT-III indicates the point where shifts are completed.

Diagnostic test mode Function
Work support This mode enables a technician to adjust some devices faster and more accurately by following the in-
dications on CONSULT-III.
Self-diagnostic results Self-diagnostic results can be read and erased quickly.
Data monitor Input/Output data in the ECU can be read.
CAN diagnostic support mon-
itor The results of transmit/receive diagnosis of CAN communication can be read.
Function test Performed by CONSULT-III instead of a technician to determine whether each system is “OK” or “NG”.
DTC work support Select the operating condition to confirm Diagnosis Trouble Codes.
ECU part number TCM part number can be read.
