Stall Speed Test (CVT): Test
- Transmission Fluid Level - Check
- HDS - Connect
1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
2. Turn the vehicle to the ON mode.
3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting . - Engine - Warm Up
1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice). - CVT Stall Speed - Test
5. Make sure the A/C switch is OFF
6. Shift the transmission to D position/mode while pressing the brake pedal firmly, then press the accelerator pedal for 6 to 8 seconds, and note the engine speed.
NOTE: Do not move the shift lever or remove your foot off the brake pedal, while raising the engine speed
7. Allow 2 minutes for cooling, then repeat the test in the all positions/modes.
NOTE:
- Do not test stall speed for more than 10 seconds at a time.
- Record the engine speed at 6 to 8 seconds after pressing the accelerator pedal. Higher engine speed will be indicated for 5 seconds.
- Stall speed tests should be used for diagnostic purposes only.
- The stall speed should be the same in all positions/modes.
- Do not test stall speed with a pressure gauge installed.
Stall Speed rpm Specification: 2, 250 rpm Service Limit: 2, 000-2, 400 rpm 5. If any of the stall speeds are out of the service limit, refer to the problems and probable causes listed in the table.
Problem Probable Causes Stall speed rpm high in all positions/modes - Transmission fluid pump worn, binding, or foreign material in transmission fluid pump
- CVT clutch pressure control solenoid valve defective
- Forward clutch slippage
- Valve body assembly defective
- Transmission fluid strainer clogged
Stall speed rpm high in R position/mode Reverse brake slippage Stall speed rpm low in all positions/modes - Engine output low
- Transmission fluid pump worn, binding, or foreign material in transmission fluid pump
- CVT drive pulley pressure control solenoid valve defective
- CVT driven pulley pressure control solenoid valve defective
- Valve body assembly defective
- Torque converter one-way clutch slippage
