## CVT Stall Speed Test

1. | Set the parking brake, and block the front wheels.

2. | Connect a tachometer to the engine, and start the engine.

3. | Make sure the A/C switch is OFF.

4. | After the engine has warmed up to normal operating temperature (the radiator fan comes on), shift to [D] position.

5. | Fully press the brake pedal and accelerator for 6 to 8 seconds, and note engine speed. Do not move the shift lever while raising engine speed.

6. | Allow 2 minutes for cooling, then repeat the test in [S], [L], and [R] positions. NOTE: Do not test stall speed for more than 10 seconds at a time. Stall speed tests should be used for diagnostic purposes only. Stall speed should be the same in [D], [S], [L], and [R] positions. Do not test stall speed with the A/T pressure gauges installed.
Stall Speed rpm in [D], [S], [L], and [R] positions:
Specification: | 2,500 rpm (min-1)
Service Limit: | 2,350-2,650 rpm (min-1)

7. | If the measurements are out of the service limit, problems and probable causes are listed in the table below.
Problem | Probable cause
