TROUBLE DIAGNOSIS — BASIC INSPECTION
Cruise Test — Part 1
1. CHECK STARTING GEAR (D1 ) POSITION
1. Drive vehicle for approx. 10 minutes to warm engine oil and ATF up to operating
temperature.
2. Park vehicle on flat surface.
3. Set overdrive control switch to “ON” position.
4. Move selector lever to “P” position.
5. Start engine.
6. Move selector lever to “D” position.
7. Accelerate vehicle by constantly depressing accelerator pedal
halfway.
8. Does vehicle start from D
1 ?
Read gear position.
Ye s o r N o
Yes >> GO TO 2
No >> Mark the box of “Vehicle Cannot Be Started From D
1 ”
on the DIAGNOSTIC WORKSHEET. Continue Road
Te s t . ATF operating temperature: 50 - 80°C (122 - 176°F)

Cruise Test — Part 2
1.CHECK STARTING GEAR (D1 ) POSITION
1. Confirm overdrive control switch is in “ON” position.
2. Confirm selector lever is in “D” position.
3. Accelerate vehicle by half throttle again.
4. Does vehicle start from D
1 ?
Read gear position.
Ye s o r N o
Ye s > > G O T O 2
No >> Mark the box of “Vehicle Does Not Start From D

the DIAGNOSTIC WORKSHEET. 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 illustration.
2. Release accelerator pedal and then quickly depress it fully.
3. Does A/T shift from D
4 to D2 as soon as accelerator pedal is depressed fully?
Read gear position and throttle position.
Ye s o r N o
Ye s > > G O T O 3
No >> Mark the box of “A/T Does Not Shift: D
1→ D2 Or Does
Not Kickdown: D
4→ D2 ” on the DIAGNOSTIC WORK-
SHEET. Continue Road Test.
