NOTE:
The tire pressure monitoring system (TPMS) does not identify the location of the malfunctioning wheel unit on the vehicle (LF, RF, LR, RR). The TPMS identifies each wheel unit as No.1, No.2, No.3 and No.4. In order to identify the location of the wheel unit, perform the following procedure.
1. Adjust the air pressure as follows:
RF: 220 kPa {2.2 kgf/cm2, 32 psi}
LF: 240 kPa {2.4 kgf/cm2, 35 psi}
LR: 260 kPa {2.6 kgf/cm2, 38 psi}
RR: 280 kPa {2.8 kgf/cm2, 40 psi}
2. Turn the ignition switch off.
3. Connect the M-MDS to the DLC-2.
4. Turn the ignition switch to the ON position.
5. Drive the vehicle at a speed of 25 km/h {15.5 mph} or more for 2 min or more.
6. Select the following PIDs using the M-MDS, and monitor them.
WU1_P
WU2_P
WU3_P
WU4_P
7. Determine which wheel unit identification code matches which wheel and tire by comparing the PID monitor values with the air pressure values set in Step 1.
8. Select the ID_LAST PID using the M-MDS, and take a note of four displayed identification codes.
9. Inspect the DTCs using the M-MDS.
