Toyota RAV4 (XA40) 2013-2018 Service Manual: Manual shifting test
- Manual shifting test
Hint:
- Through this test, it can be determined whether the trouble occurs in the electrical circuit or if it is a mechanical problem in the transaxle.
- If any abnormalities are found in the following test, the problem is in the transaxle itself.
- Disconnect the connector of the transmission wire.
Hint:
It is possible to deactivate the electrical shift control by disconnecting the transmission wire. The gear positions can then be changed mechanically with the shift lever.
- Drive with the transmission wire disconnected.
Move the shift lever to each position to check whether the gear position changes as shown in the table below.
- Connect the connector of the transmission wire.
- Clear the dtc (see page ax-29).
Initialization
- Reset memory
Notice:
- Perform the reset memory procedures (a/t initialization) when replacing the automatic transaxle assembly, engine assembly or ecm.
- Reset memory can be performed only with the intelligent tester.
Hint:
The ecm memorizes the vehicle conditions when the ect controls the automatic transaxle assembly and engine assembly. Therefore, when the automatic transaxle assembly, engine assembly, or ecm has been replaced, it is necessary to reset the memory so that the ecm can memorize the new information.
The reset procedures are as follows.
- Turn the ignition switch off.
- Connect the intelligent tester to the can vim. Then connect the can vim to the dlc3.
- Turn the ignition switch on and turn the tester on.
- Enter the following menus: diagnosis / enhanced obd ii.
- Perform the reset memory procedures from the
Engine menu.
Caution:
After performing the reset memory procedures, be sure to perform the road test (see page ax-12) as described earlier.
Hint:
The ecm learns through the road test.
Hydraulic test
Measure line pressure
Notice:
Perform the test at the normal operating atf
temperature: 50 to 80°c (122 to 176°f).
The line pressure test should always be
performed with at least ...

Engine control system malfunction
Description
If a malfunction in the engine control system is detected, the operations of
vsc and trc are prohibited
by the fail-safe function. When the signals from the engine are input normally,
the fail-safe is canceled and
the dtc is not stored.
Inspection procedure
Check harn ...
PCS (Pre-Collision System)
The pre-collision system
uses a radar sensor and
front camera to detect
objects in front of
the vehicle. When the system
determines that the
possibility of a frontal collision
with an object is high,
a warning operates to urge
the driver to take evasive
action and the potential
brake pressure is inc ...

System diagram
Hint:
The abs and traction actuator (skid control ecu)
detects and stores steering sensor and yaw rate
sensor dtcs and performs dtc communication by
receiving information from the steering sensor and
yaw rate sensor.
The ecm uses the can communication sy ...
