Mazda 2: Symptom Troubleshooting

NO.1 TPMS WARNING LIGHT ILLUMINATES CONTINUOUSLY

CAUTION:

• The tire pressure cannot be measured accurately after driving for a long period due to the internal temperature and pressure. Stop the vehicle for approx. 1 hour and then perform the tire pressure measurement and adjustment.
• Use a high accuracy digital gauge for measurement of the tire pressure.

NOTE:

• If the DTC clearing procedure is implemented, the TPMS warning light turns off.

NO.2 TPMS WARNING LIGHT (LOW PRESSURE WARNING) ILLUMINATES AFTER ENGINE START AND TURNS OFF AFTER DRIVING FOR PERIOD OF TIME

• The tire pressure normally decreases by approx. 7 kPa {0.07 kgf/cm2, 1.00 psi} per month even if the tire is normal.
• The Snapshot (temperature and pressure) stored when the TPMS warning light is turned on and off can be verified by operating the M-MDS.
