  1. Set the ID transmission condition to "ID Registration is complete".

    HINT:
    If the operations of steps (d) to (f) do not complete within 5 min., the mode will return to normal operation mode.


4. CONFIRMATION OF TRANSMITTER ID REGISTRATION

  1. Set the tire pressure of 4 wheels to the specified value.

    		270 (2.7, 39)
    320 (3.2, 46)*
    *: When at least 4 people are in the vehicle.

  1. Connect the intelligent tester to DLC3.

  1. Turn the engine switch on (IG).

  1. Select "SIGNAL CHECK" mode on the intelligent tester (Click here).

  1. Perform forced transmission of the transmitter IDs for 4 wheels.

    1. When rapidly reducing the pressure, remove the valve core (above 20 kPa/15 sec.).

      HINT:
      The transmitter ID can be transmitted by rapidly reducing the tire air pressure.

    2. Perform the steps mentioned above to 4 tires.

      HINT:
      When rapidly reducing the pressure, remove the valve core (above 20 kPa/15 sec.).

  1. Check that test mode DTCs C2181/81, C2182/82, C2183/83 and C2184/84 are all erased.

    HINT:
    1. The transmitter ID registration is completed when the test mode DTCs are erased.
    2. If they haven't been erased, reset the tire pressure to the specified value and rotate the tire 90 to 270 degrees. Then perform forced transmission of the transmitter IDs of 4 wheels. If they are still output, register the transmitter IDs.

  1. Set the tire pressure of 4 wheels to the specified value.



5. PROCEDURE FOR DETERMINING THE INSTALLED WHEEL'S TRANSMITTER ID STATUS ("MAIN" OR "2nd")

  1. Turn the engine switch on (IG).

  1. Set the tire select switch to the "MAIN" position.

  1. Set the tire pressure of all wheels to the specified value.

    Tire Size
    		Front
    kPa (kgf/cm2, psi)
    		Rear
    kPa (kgf/cm2, psi)
    For driving at speeds under 160 km/h (100 mph)
    		For driving at speeds of 160 km/h (100 mph) or over

    *: When at least 4 people are in the vehicle.

  1. Rapidly reduce the pressure of any wheel to 120 kPa (1.2 kgf/cm2, 17 psi).

  1. Check the following items. If both of them are true, the transmitter ID of the currently installed wheel is registered in the "MAIN".

    1. Tire pressure warning light comes on.
    2. The tire pressure of any tire is 120 kPa (1.2 kgf/cm2, 17 psi) when measured with the intelligent tester.

  1. If either of the conditions is not true, switch the tire pressure warning switch to "2nd" and perform steps (c) to (e). If both are true, the transmitter ID of the currently installed wheel is registered in "2nd".
