TROUBLE DIAGNOSIS
8.CHECK LOCK-UP RELEASE
Check lock-up cancellation by depressing brake pedal lightly to decelerate.
With CONSULT-II
Select “TCC SOLENOID” with “MAIN SIGNALS” mode for “A/T”. Refer toAT-77, "
CONSULT-II REFERENCE
VA L U E".
Does lock-up cancel?
YES >> GO TO 9.
NO >> Enter a check mark at “Lock-up Is Not Released” onAT-38, "
DIAGNOSTIC WORKSHEET",then
continue the road test.
9.CHECK SHIFT-DOWN D5®D4
Decelerate by pressing lightly on brake pedal.
With CONSULT-II
Read the gear position and engine speed. Refer toAT-83, "
DATA MONITOR MODE".
When the A/T shift-down D
5®D4, does the engine speed drop smoothly back to idle?
YES >> 1. Stop the vehicle.
2. Go toAT-50, "
Cruise Test - Part 2".
NO >> Enter a check mark at “Engine Speed Does Not Return to Idle” onAT-38, "
DIAGNOSTIC WORK-
SHEET", then continue the road test. Go toAT-50, "Cruise Test - Part 2".
CruiseTest-Part2ECS00FX4
1.CHECK STARTING FROM D1
1. Move selector lever to “D” position.
2. Accelerate at half throttle.
With CONSULT-II
Read the gear position. Refer toAT-83, "
DATA MONITOR MODE".
Does it start from D
1?
YES >> GO TO 2.
NO >> Enter a check mark at “Vehicle Cannot Be Started from D
1”onAT-38, "DIAGNOSTIC WORK-
SHEET", then continue the road test.
2.CHECK SHIFT-UP D1®D2
Press accelerator pedal down all the way and inspect whether or not the A/T shifts up (D1®D2)atthecor-
rect speed. Refer toAT-52, "
Vehicle Speed at Which Gear Shifting Occurs".
With CONSULT-II
Read the gear position, throttle degree and vehicle speed. Refer toAT-83, "
DATA MONITOR MODE".
Does the A/T shift-up D
1®D2at the correct speed?
YES >> GO TO 3.
NO >> Enter a check mark at “A/T Does Not Shift: D
1®D2”onAT-38, "DIAGNOSTIC WORKSHEET",
then continue the road test.
3.CHECK SHIFT-UP D2®D3
Press accelerator pedal down all the way and inspect whether or not the A/T shifts up (D2®D3)atthecor-
rect speed. Refer toAT-52, "
Vehicle Speed at Which Gear Shifting Occurs".
With CONSULT-II
Read the gear position, throttle degree and vehicle speed. Refer toAT-83, "

Does the A/T shift-up D
2®D3at the correct speed?
YES >> GO TO 4.
NO >> Enter a check mark at “A/T Does Not Shift: D

CONSULT-II Function (A/T)ECS00FXA
CONSULT-II can display each diagnostic item using the diagnostic test modes 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).
