Mazda 2: Malfunctioning Wheel Unit Identification
NOTE:
- The tire pressure monitoring system (TPMS) does not identify the
location of the
malfunctioning wheel unit on the vehicle (RF, LF, 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. Switch the ignition to off.
3. Connect the M-MDS to the DLC-2.
4. Switch the ignition to ON.
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.
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.

Diagnostic procedure


DTC C2011:49/C2012:49/C2013:49/C2014:49

Diagnostic procedure


DTC C2011:87/C2012:87/C2013:87/C2014:87

Diagnostic procedure


NOTE:
- If the wheel unit has been newly replaced, the TPMS warning light may
flashes before
the ID registration is complete, and DTC C2011:87, C2012:87, C2013:87 and
C2014:87
may be stored in the memory. In this case, reimplement the wheel unit ID
registration,
and after confirming that the TPMS warning light is no longer flashing,
erase the DTC.
If the TPMS warning light does not go out, a malfunction on any one of the
wheel units
may have occurred and the ID registration will not have been correctly
performed.
Repeat the diagnostic procedure from Step 1 and perform and inspection.
