Toyota RAV4 Service Manual: Transmitter id
Description
Hint:
It is necessary to perform the procedure to identify the tire pressure monitor valve that is malfunctioning because it cannot be identified by the output dtc.
Inspection procedure
Notice:
It is necessary to register an id code after replacing the tire pressure warning valve and transmitter and/or the tire pressure warning ecu (see page tw-9).
- Identify transmitter (corresponding to dtc)
- Set the pressure of each tire to the specified value.
Standard pressure: 220 kpa (2.2 Kgf /cm2, 32 psi)
- Connect the intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch on.
- Select tirepress by following the prompts displayed on the intelligent tester.
Notice:
It may take up to 1 minute to display the updated data.
- Rapidly release the tire pressure from any tire by 40 kpa (0.4 Kgf/cm2, 5.8 Psi) for 30 seconds or more.
Hint:
- Identify the malfunctioning tire pressure warning valve and transmitter by rapidly releasing the tire pressures from each tire.
- Record which tirepress data (id1 to id5) corresponds to each tire.
- Check the data list.
Result
Notice:
- When the tirepress data (ids 1 to 5) changes, reset the tire pressure of the tires to the specified value, rotate the tires 90 to 270° and recheck.
- When the transmitter is normal, record the tire location and the transmitter id.
- When one of the tirepress data (ids 1 to 5) changes, repeat the same procedure on the rest of the tires one by one to identify which tire pressure warning valve and transmitter the dtc corresponds to.
- When the tirepress data (ids 1 to 5) has been changed, identify the malfunctioning tire pressure warning valve and transmitter by using recorded id numbers and the output dtc.
- Set the pressure of each tire to the specified value.
Standard pressure: 220 kpa (2.2 Kgf /cm2, 32 psi)

Description
The tire pressure warning valve and transmitter constantly sends radio waves
to the tire pressure warning
ecu.

Basic inspection
When a malfunction is not confirmed by the dtc check,
troubleshooting should be carried out in all circuits
considered to be possible causes of the problem. In many
cases, by carrying out the basic engine check shown in the
following flowchart, the location of the problem can be found
quickly a ...
Vehicle speed sensor "A"
description
The speed sensor detects the wheel speed and sends the appropriate signals to
the skid control ecu.
The skid control ecu converts these wheel speed signals into a 4-pulse signal
and outputs it to the ecm
via the combination meter. The ecm determines the vehicle speed based o ...
Data list / active test
Hint:
Using the intelligent tester's data list allows switch, sensor,
actuator and other item values to be read without removing
any parts. Reading the data list early in troubleshooting is
one way to save time.
