TW
(e) Rapidly release the pressure from each wheel by
approximately 40 kPa (0.4 kgf/cm
2, 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:
• It may take up to 1 minute to display the
updated tire pressure data.
• 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.
(2) 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/cm
2, 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).

(e) Rapidly release the tire pressure from any tire by 40 kPa
(0.4 kgf/cm
2, 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.
(f) Check the DATA LIST.

NOTICE:
• It may take up to 1 minute to display the updated
tire pressure data.
• 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.
(g) When 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.
(h) Set the pressure of each tire to the specified value.
Standard pressure:
220 kPa (2.2 kgf/cm
2, 32 psi)
(i) Check all transmitters of the tires.
