Toyota RAV4 Service Manual: Transmitter id

Toyota RAV4. Transmitter id


Description

The tire pressure warning valve and transmitter that is installed in the tires and wheels measures the air pressure of the tires. The measured values are transmitted to the tire pressure warning receiver on the body as radio waves and then sent to the tire pressure warning ecu. The ecu compares the measured air pressure values with the air pressure threshold. When the measured air pressure values are less than this threshold, the warning light in the combination meter turns on.

The tire pressure warning ecu stores a dtc when the tire pressure monitor valve stops transmitting signals. At this time, forcibly transmit the signals by releasing the tire pressure rapidly. The stored dtc is cleared when the signal transmission is resumed.

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 antenna and receiver and/or the tire pressure warning ecu (see page tw-9).

  1. Perform forced transmission of transmitter id of all wheels

  1. Set the pressure of each tire to the specified value.

    Standard pressure: 220 kpa (2.2 Kgf/cm2, 32 psi)

  2. Connect the intelligent tester (with can vim) to the dlc3.
  3. Turn the ignition switch on.
  4. Select tirepress by following the prompts displayed on the intelligent tester.

Toyota RAV4. Perform forced transmission of transmitter id of all wheels


  1. Rapidly release the pressure from each wheel by approximately 40 kpa (0.4 Kgf/cm2, 5.8 Psi) for 30 seconds or more.
  1. Check that each tire pressure data displayed on the intelligent tester screen changes.

Ok: the tire pressure data displayed on the intelligent tester screen changes with the value of the tire pressure.

Notice:

  1. After confirming that the tire pressure data displayed on the intelligent tester screen has changed, set the pressure of each tire to the specified value.

Standard pressure: 220 kpa (2.2 Kgf/cm2, 32 psi)

Hint:

If the tire pressure data displayed on the intelligent tester screen has not changed after rechecking, go to the troubleshooting procedures of dtcs c2121/ 21 to c2125/25 which indicate transmission or reception malfunctions (see page tw-28).
