2008 - MX-5 - Suspension

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

CAUTION:

The tire pressure cannot be measured accurately after driving for a long period due to increased 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:

The tire pressure decreases spontaneously by approx. 7 kPa {0.07 kgf/cm², 1.02 psi} per month even if the tire is normal.

The FFD (temperature and pressure) stored when the TPMS warning light is turned on of off can ben verified by operating the M-MDS.


2	TPMS warning light (low pressure warning) illuminates after engine start and turns off after driving for a period of time.
[TROUBLESHOOTING HINTS] The tire pressure decreases (approaches value to illuminate TPMS warning light) when the internal temperature of the tire is low.
STEP	INSPECTION		ACTION
1	INSPECT THE TIRE Is there any foreign object adhering to the tire?	Yes	Remove any foreign object. Replace the tire if necessary, and then go to the next step.
1		No	Go to the next step.
2	MEASURE THE TIRE PRESSURE WHEN THE TIRES ARE COLD Has the tire pressure decreased (approaches value to illuminate TPMS warning light)?	Yes	Adjust the tire pressure to the specification while the tires are cold, and then go to the next step.
2		No	Go to the next step.
3	IS THE MALFUNCTION CORRECTED?	Yes	Troubleshooting completed.
3	IS THE MALFUNCTION CORRECTED?	No	Verify troubleshooting again and return to Step 1 if the malfunction recurs.
