(g) Rapidly reduce the tire pressure for each wheel by at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds. If the "ID Tire Inflation
Pressure" data displayed on the tester (ID1 to ID5) does not change, the tire pressure warning valve and transmitter corresponding to
the unchanged "ID Tire Inflation Pressure" data was the cause of the output DTC.
HINT
* Identify the malfunctioning tire pressure warning valve and transmitter by repeatedly decreasing the tire pressure for each
tire.
* Record which "ID Tire Inflation Pressure" data (ID1 to ID5) corresponds to which tire.
Tire Pressure Monitor
HINT
*: 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: C Code Charts/C2121.
(h) Check the DATA LIST.
Result:
NOTICE:
* When 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锟斤拷. Then rapidly release the tire pressure and recheck the data.
* Record the transmitter IDs and positions of transmitters that are normal.
(i) When the "ID Tire Inflation Pressure" data (ID1 to ID5) has changed, repeat this procedure to identify the tire pressure warning valve
and transmitter that corresponds to the DTC.
(j) When all of the "ID Tire Inflation Pressure" data (ID1 to ID5) has changed, identify the malfunctioning tire pressure warning valve
