TROUBLE DIAGNOSIS — BASIC INSPECTION

Cruise Test — Part 1
1. CHECK STARTING GEAR (D1 ) POSITION
1. Drive vehicle for approximately 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.
Read gear position. Refer to AT- 2 4 4 , "
DATA MONITOR
MODE (A/T)" .
Does vehicle start from D
1 ?
YES >> GO TO 2.
NO >>

Mark the box on the DIAGNOSTIC WORKSHEET.

GO TO AT- 3 0 1 , "Vehicle Cannot Be Started From D1"
.

Continue “Road Test”. ATF operating temperature: 50 - 80°C (122 - 176°F)

Cruise Test — Part 3
1. CHECK SHIFT DOWN (D4 TO D3 )
1. Confirm overdrive control switch is in ON.
2. Confirm selector lever is in D position.
3. Accelerate vehicle using half-throttle to D
4 .
4. Release accelerator pedal.
5. Set overdrive control switch to OFF while driving in D
4 .
Read gear position and vehicle speed. Refer to AT- 2 4 4 ,
"DATA MONITOR MODE (A/T)" .
Does A/T shift from D
4 to D3 (O/D OFF)?
YES >> GO TO 2.
NO >>

Mark the box on the DIAGNOSTIC WORKSHEET.

GO TO AT- 3 1 8 , "A/T Does Not Shift: D4 → D3 , When
Overdrive Control Switch “ON” → “OFF”" .

Continue “Road Test”.
2. CHECK ENGINE BRAKE
Check engine brake.
Does vehicle decelerate by engine brake?
YES >> GO TO 3.
NO >>

Mark the box on the DIAGNOSTIC WORKSHEET.

GO TO AT- 3 2 2 , "Vehicle Does Not Decelerate By
