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
Evaluation:

analysis, try to reproduce the symptoms. If the
problem is that the transaxle does not shift up, shift
down, or ...

Catalyst system efficiency below threshold (bank 1)
Monitor description
The ecm uses sensors mounted in front of and behind the three-way catalytic
converter (twc) to
monitor its efficiency.
The first sensor, the air-fuel ratio (a/f) sensor, sends pre-catalyst
information to the ecm. The second
sensor, the heated oxygen (ho2) sensor, se ...
