Inspection Procedure
- PERFORM FORCED TRANSMISSION OF TRANSMITTER ID OF ALL WHEELS
- Set the tire pressure to the specified value (See INSPECTION ).
- Connect Techstream to the DLC3.
- Turn the ignition switch on (IG) and turn the tester on.
- Enter the following menus:
- Select: Chassis / Tire Pressure Monitor / Data List
- Check the values by referring to the table below.

*: It may take about 2 or 3 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 C2125/25 (See DTC C2121/21 NO SIGNAL FROM TRANSMITTER ID1 IN MAIN MODE; DTC C2122/22 NO SIGNAL FROM TRANSMITTER ID2 IN MAIN MODE; DTC C2123/23 NO SIGNAL FROM TRANSMITTER ID3 IN MAIN MODE; DTC C2124/24 NO SIGNAL FROM TRANSMITTER ID4 IN MAIN MODE; DTC C2125/25 NO SIGNAL FROM TRANSMITTER ID5 IN MAIN MODE; DTC C2181/81 TRANSMITTER ID1 NOT RECEIVED (TEST MODE DTC); DTC C2182/82 TRANSMITTER ID2 NOT RECEIVED (TEST MODE DTC); DTC C2183/83 TRANSMITTER ID3 NOT RECEIVED (TEST MODE DTC); DTC C2184/84 TRANSMITTER ID4 NOT RECEIVED (TEST MODE DTC); DTC C2185/85 TRANSMITTER ID5 NOT RECEIVED (TEST MODE DTC) ). - Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm2 , 5.8 psi) within 30 seconds.
- Check that each tire pressure displayed on Techstream screen has changed.
OK:
Each tire pressure displayed on Techstream screen will change to the value of the tire pressure.
NOTE:- It takes about 2 or 3 minutes to display the updated tire pressure data.
- If the "ID Tire Inflation Pressure" data has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270°. Then rapidly release the tire pressure and recheck it.
- After confirming that all of the tire pressure data displayed on Techstream screen has changed, set the tire pressure to the appropriate specified values.
HINT:
If the tire pressure data displayed on Techstream screen has not changed after rechecking, inspect for another problem (malfunction in transmission or reception function) (See DTC C2121/21 NO SIGNAL FROM TRANSMITTER ID1 IN MAIN MODE; DTC C2122/22 NO SIGNAL FROM TRANSMITTER ID2 IN MAIN MODE; DTC C2123/23 NO SIGNAL FROM TRANSMITTER ID3 IN MAIN MODE; DTC C2124/24 NO SIGNAL FROM TRANSMITTER ID4 IN MAIN MODE; DTC C2125/25 NO SIGNAL FROM TRANSMITTER ID5 IN MAIN MODE; DTC C2181/81 TRANSMITTER ID1 NOT RECEIVED (TEST MODE DTC); DTC C2182/82 TRANSMITTER ID2 NOT RECEIVED (TEST MODE DTC); DTC C2183/83 TRANSMITTER ID3 NOT RECEIVED (TEST MODE DTC); DTC C2184/84 TRANSMITTER ID4 NOT RECEIVED (TEST MODE DTC); DTC C2185/85 TRANSMITTER ID5 NOT RECEIVED (TEST MODE DTC) ).
