• Continue “Road Test”.
8.CHECK SHIFT-DOWN (D4 TO D3 )
Decelerate vehicle by applying foot brake lightly. Read gear position and engine speed. Refer to AT-77, "
CON-
SULT-III Function (TRANSMISSION)" .
Does engine speed return to idle smoothly when A/T is shifted from
D4 to D3 ?
YES >> 1. Stop vehicle. 2. Go to AT-61, "
Cruise Test - Part 2" .
NO >> • Mark the box on the “D iagnostic Worksheet Chart”.
•Go to AT-196, "
Engine Speed Does Not Return to Idle
(Light Braking D4→ D3)" .
• Continue “Road Test”.

1.CHECK STARTING GEAR (D1 ) POSITION
1. Push overdrive control switch. (OD OFF indicator lamp is off.)
2. Move selector lever to “D” position.
3. Accelerate vehicle by half throttle again. Read gear position. Refer to AT-77, "
CONSULT-III Func-
tion (TRANSMISSION)" .
Does vehicle start from D
1 ?
YES >> GO TO 2.
NO >> • Mark the box on the “D iagnostic Worksheet Chart”.
•Go to AT-187, "
Vehicle Cannot Be Started from D1" .
• Continue “Road Test”.
2.CHECK SHIFT-UP AND SHIFT-DOWN (D3 TO D4 TO D2 )
1. Accelerate vehicle to 80 km/h (50 MPH) as shown in the figure.
2. Release accelerator pedal and then quickly depress it fully. Read gear position and th rottle opening. Refer to AT-77,
"CONSULT-III Function (TRANSMISSION)" .
Does A/T shift from D
4 to D2 as soon as accelerator pedal is
depressed fully?
YES >> GO TO 3.
NO >> • Mark the box on the “D iagnostic Worksheet Chart”.
•Go to AT-189, "
A/T Does Not Shift: D1→ D2or Does
Not Kickdown: D4→ D2" .
• Continue “Road Test”.
3.CHECK SHIFT-UP (D2 TO D3 )
