INSPECTION PROCEDURE
NOTICE:
1 CHECK FREQUENCY RECEIVING CONDITION
(a) Check if the vehicle is not located in areas such as described below: (1) Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.
HINT: If the vehicle is located in areas described above, the tire pressure warning light may come on after blinking 1 minute only in a particular area.
(2) Devices using similar radio frequencies are used in the vehicle.
OK: Facilities, or devices that use similar radio frequencies are not located in the vicinity of the vehicle.
HINT: Radio frequency may be interrupted due to surroundings or devices installed by the user.
2 IDENTIFY TRANSMITTER CORRESPONDING TO DTC
(a) Set the tire pressure to the appropriate specified values.
Cold tire inflation pressure
(b) Make sure that the ignition switch is off.
(c) Connect the intelligent tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Select "TIREPRESS" by following the prompts displayed on the intelligent tester.
TIRE PRESSURE:
HINT: *: It may take about 5 to 6 minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 (See page TW-42).
(f) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kg/cm2, 5.8 psi) within 30 seconds.
(g) Check the DATA LIST.
NOTICE:
(h) After confirming that one of "TIREPRESS" data for one tire (ID1 to ID4) has changed, repeat this procedure one by one. Identify the transmitter that corresponds to a DTC.
