Toyota RAV4 (XA40) 2013-2018 Service Manual: Mechanical system tests
- Stall speed test
Hint:
This test is to check the overall performance of the engine and transaxle.
Notice:
- Do not perform the stall speed test longer than 5 seconds.
- To ensure safety, perform this test in an open and level area that provides good traction.
- The stall speed test should always be performed with at least 2 people. One person should observe the condition of the wheels and wheel chocks while the other is performing the test.
- Connect the intelligent tester to the can vim. Then connect the can vim to the dlc3.
- Run the vehicle until the transmission fluid temperature has reached 50 to 80°c (122 to 176°f).
- Allow the engine to idle with the air conditioning off.
- Chock all 4 wheels.
- Set the parking brake and keep the brake pedal depressed firmly with your left foot.
- Move the shift lever to the d position.
- Depress the accelerator pedal as much as possible with your right foot.
- Read the engine rpm (stall speed) and release the accelerator pedal immediately.
Standard value: 2,150 to 2,450 rpm
Evaluation:
Notice:
Perform the test at the normal operating atf temperature of 50 to 80°c (122 to 176°f).
- Shift time lag test
Hint:
This test is to check the condition of the direct clutch, forward clutch, 1st brake and reverse brake.
- Connect the intelligent tester to the can vim. Then connect the can vim to the dlc3.
- Run the vehicle until the transmission fluid temperature has reached 50 to 80°c (122 to 176°f).
- Allow the engine to idle with the air conditioning off.
- Set the parking brake and keep the brake pedal depressed firmly.
- Check the d range time lag.
- Move the shift lever to n and wait for 1 minute.
- Move the shift lever to d and measure the time until the shock is felt.
- Repeat the 2 procedures above 3 times, and calculate the average time of the 3 tests.
- Check the r range time lag.
- Move the shift lever to n and wait for 1 minute.
- Move the shift lever to r and measure the time until the shock is felt.
- Repeat the 2 procedures above 3 times, and calculate the average time of the 3 tests.
Standard value:
D range time lag is less than 1.2 Seconds
R range time lag is less than 1.5 Seconds
