Check hold lock-up. With CONSULT-II
Select “TCC SOLENOID” with the “MAIN SIGNAL” mode for “A/T”. Refer to AT- 9 0 , "

Does it maintain lock-up status?
YES >> GO TO 8.
NO >> Enter a check mark at “A/T Does Not Hold lock-up Condition” on the AT- 4 7 , "
DIAGNOSTIC
WORKSHEET" , then continue the road test.
8. CHECK LOCK-UP RELEASE
Check lock-up cancellation by depressing brake pedal lightly to decelerate. With CONSULT-II
Select “TCC SOLENOID” with the “MAIN SIGNAL” mode for A/T. Refer to AT- 9 0 , "

Does lock-up cancel?
YES >> GO TO 9.
NO >> Enter a check mark at “Lock-up Is Not Released” on the AT- 4 7 , "

then continue the road test.
9. CHECK SHIFT-DOWN D5 → D4
Decelerate by pressing lightly on the brake pedal. With CONSULT-II
Read the gear position and engine speed. Refer to AT- 9 6 , "
DATA MONITOR MODE" .
When the A/T shift-down D5
→ D4, does the engine speed drop smoothly back to idle?
YES >> 1. Stop the vehicle. 2. Go to AT- 6 0 , "

CONSULT-II Function (A/T)ACS002M9
CONSUT-II can display each diagnostic item using the diagnostic test models shown following.
FUNCTION
CONSULT-II REFERENCE VALUE
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II 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-II indicates the point where shifts are completed.
3. Display of solenoid valves on CONSULT-II changes at the start of shifting, while gear position is displayed upon completion of shifting (which is computed by TCM).
