Stall Test: Notes

2013 Suzuki SX4 Crossover, Automatic CVT TransSECTION Notes
WARNING: This page is about a different car, the 2011 Suzuki SX4. However, it is still accessible from the selected car via links, so may be relevant.

This test is to check overall performance of CVT and engine by measuring stall speed at "D" and "R" ranges.

CAUTION: If proper precautions are not taken when performing stall tests, a CVT failure may result due to an excessive rise in CVT fluid temperature.
  • Do not continue running the engine for longer than 5 seconds at stall speed.
  • After performing a stall test, be sure to allow the engine to run at idle for longer than 1 minute before performing another stall test.
  1. Check CVT fluid level, see CVT Fluid Check .
  2. Apply parking brake and block wheels.
  3. Install tachometer.
  4. Start engine with select lever shifted to "P" range.
  5. Depress brake pedal fully.
  6. Shift select lever to "D" range and depress accelerator pedal fully while watching tachometer. Read engine RPM quickly when it has become constant (stall speed).
  7. Release accelerator pedal immediately after stall speed is checked.
  8. In the same way, check stall speed in "R" range.
  9. Stall speed should be within the following specification.

    Engine stall speed
