SYMPTOM TROUBLESHOOTING HINTS
DIAGNOSTIC PROCEDURE
after repeating this step, the tire may be flat.
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/cm
2
, 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 or off can be verified by operating the M-MDS or equivalent.

2
MEASURE THE TIRE PRESSURE WHEN
THE ENGINE IS COLD

(approaches value to illuminate TPMS
warning light)?
Yes
Adjust the tire pressure to the specification,
and then go to the next step.
No Go to the next step.
3
IS THE MALFUNCTION CORRECTED?
