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
Engine Brake" .

Continue “Road Test”.
