Functional Test




Functional Test

The purpose of the stall test is to inspect overall performance of the A/T and the engine by measuring the stall speed in drive (D) and reverse (R) range.

1. Wedge the 4 wheels and fully apply the parking brake. Lock the vehicle in place.
2. Fully press on the brake pedal with left foot.

Important: Do not continuously run longer than 5 seconds, extreme increasing of the oil temperature may occur.

3. Shift into drive (D) and reverse (R) range, fully press on accelerator pedal with right foot.

The standard stall speed is 2,240-2,540 RPM.
Make sure to keep interval for more than 1 minute between stall tests.
