MALFUNCTIONING WHEEL UNIT IDENTIFICATION [INSTRUMENT CLUSTER (DIRECT TPMS (WITHOUT TPMS SET SWITCH))]

id020212812200

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.  Connect the M-MDS to the DLC-2.

3.  Drive the vehicle at a speed of 25 km/h {16 mph} or more for 2 min or more.

4.  Select the following monitor items using the M-MDS, and verify them.

(See PID/DATA MONITOR INSPECTION [INSTRUMENT CLUSTER (DIRECT TPMS (WITHOUT TPMS SET SWITCH))].)

•  WU1_P

•  WU2_P

•  WU3_P

•  WU4_P

5.  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.
