TROUBLE DIAGNOSIS
When releasing accelerator pedal from D5, check lock-up from D5 to L/U. Refer to AT-58, "Vehicle Speed at
Which Lock-up Occurs/Releases".
With CONSULT-III
Select “TCC SOLENOID” with the “DATA MONI TOR” mode for “TRANSMISSION”. Refer to AT-84, "
CON-
SULT-III Function (TRANSMISSION)".
Does it lock-up?
YES >> GO TO 7.

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.
