CHECK LOCK-UP
When releasing accelerator pedal from D5 (closed throttle position signal: OFF), check lock-up from D5 to L/U.
●
Refer to
AT-62, "Vehicle Speed at Which Gear Shifting Occurs"
.
With CONSULT-II
Select “TCC SOLENOID” with the “MAIN SIGNAL” mode for A/T.
Does it lock-up?
YES
>> GO TO 7.
NO
>> Enter a check mark at “A/T Does Not Perform Lock-up” on the diagnostics worksheet, then con-
tinue the road test.
7.
CHECK LOCK-UP HOLD
Check hold lock-up.
With CONSULT-II
Select “TCC SOLENOID” with the “MAIN SIGNAL” mode for A/T.
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 diagnostics 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.
Does lock-up cancel?
YES
>> GO TO 9.
NO
>> Enter a check mark at “Lock-up Is Not Released” on the diagnostics worksheet, 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.
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 Cruise test - Part 2 (Refer to
NO
>> Enter a check mark at “Engine Speed Does Not Return to Idle” on the diagnostics worksheet, then
continue the road test. Go to Cruise test - Part 2 (Refer to
).
Cruise Test - Part 2
ECS00EFA
1.
CHECK STARTING FROM D1
1.
Move selector lever to “D” position.
2.
Accelerate at half throttle.
With CONSULT-II
Read the gear position.
Does it start from D1?
YES
>> GO TO 2.
NO
>> Enter a check mark at “Vehicle Cannot Be Started From D1” on the diagnostics worksheet, then
continue the road test.

2.
CHECK SHIFT-UP D1
→
D2
Press the accelerator pedal down all the way and inspect whether or not the transmission shifts up (D1
→
D2)
at the correct speed.
●
Refer to
AT-62, "Vehicle Speed at Which Gear Shifting Occurs"
With CONSULT-II
Read the gear position, throttle position and vehicle speed.
Does the A/T shift-up D1
→
D2 at the correct speed?
YES
>> GO TO 3.
NO
>> Enter a check mark at “A/T Does Not Shift: D1
→
D2” on the diagnostics worksheet, then continue
the road test.
3.
CHECK SHIFT-UP D2
→
D3
Press the accelerator pedal down all the way and inspect whether or not the transmission shifts up (D2
→
D3)
at the correct speed.
●
Refer to
AT-62, "Vehicle Speed at Which Gear Shifting Occurs"
With CONSULT-II
Read the gear position, throttle position and vehicle speed.
Does the A/T shift-up D2
→
D3 at the correct speed?
YES
>> GO TO 4.
NO
>> Enter a check mark at “A/T Does Not Shift: D2
→
D3” on the diagnostics worksheet, then continue
the road test.
4.
CHECK SHIFT-UP D3
→
D4 AND ENGINE BRAKE
When the transmission changes speed D3
→
D4, return the accelerator pedal.
With CONSULT-II
Read the gear position.
Does the A/T shift-up D3
→
D4 and apply the engine brake?
YES
>> 1. Stop the vehicle.
2. See
NO
>> Enter a check mark at “A/T Does Not Shift: D3
→
D4” on the diagnostics worksheet, then continue
the road test.
Cruise Test - Part 3
ECS00EFB
1.
CHECK SHIFT-DOWN
1.
Confirm overdrive control switch is ON position.
2.
Confirm gear selector lever is in “D” position.
3.
Accelerate vehicle using half-throttle to D
5
.
4.
Release accelerator pedal.
5.
Set overdrive control switch to OFF position while driving in D
5
.
With CONSULT-II
Read the gear position.
Does A/T shift from D
5
to D
4
(O/D OFF)?
YES
>> GO TO 2.
NO
>> Enter a check mark at “A/T does not shift: 5th gear
→
