Tire Pressure Warning System

TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: C2121/21-C2125/25,C2181/81-C2185/85: No Signal from Transmitter ID1
C2185/85 - Transmitter ID5 not Received (Test Mode DTC) - Continued

Tire Pressure Monitor

HINT
*: It may take about 2 or 3 minutes until the values are displayed.

(g) Rapidly reduce the tire pressure for each wheel by at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds.

(h) Check the DATA LIST.

NOTICE:
* It takes about 2 or 3 minutes to display the updated tire pressure data.
* 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°. Then rapidly release the tire pressure and recheck the data.
* Record the "ID Tire Inflation Pressure" data transmitter ID that corresponds to each tire.

(i) After confirming that the "ID Tire Inflation Pressure" data for one tire (ID1 to ID5) has changed, repeat this procedure one by one. Identify the transmitter that corresponds to the DTC.
