The TPMS (tire pressure monitoring system) has the
low tire pressure indicator and the TPMS indicator.
 If the system detects low pressure in any of the four tires, the low tire pressure indicator comes on.
 When this happens, inflate the air and test-drive the vehicle at 45 km/h (28 mph) or more for at least 1
minute, and the low tire pressure indicator will go off.
 If the control unit detects a problem in the system during an indication of low tire pressure, it turns off
the low tire pressure indicator, stores the DTC(s), and
turns on the TPMS indicator.
 If a problem is detected in the system, the TPMS indicator comes on.
 If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on.
If the system is OK, the TPMS indicator and the low
tire pressure indicator should come on when you turn
the ignition switch to ON (II), and then go off 2
seconds later. If they don’t, there is a problem with
the system. If the system detects low pressure in any of the four
tires, the low tire pressure indicator comes on, and the
control unit sets one or more of these codes: DTC 11,
13, 15, 17. When the tire pressure returns to normal,
and the TPMS control unit receives the normal pressure
signal from the tire pressure sensor, the control unit
turns off the indicator. However TPMS control unit still
retains the DTC(s).
NOTE: It is necessary to test-drive the vehicle at
45 km/h (28 mph) or more for at least 1 minute so that
tire pressure sensor transmits the signal.
The pressures increase slightly as the temperature in
the tires rises during driving.
Pressures can also increase or decrease slightly with
changes in outside air temperature.
A temperature change of about 10 °C (18 °F) changes
tire pressure by about 10 kPa (0.1 kgf/cm , 1.5 psi). If the
temperature drops, tire pressure could decrease just
enough to turn on the low tire pressure indicator, but
later, the tire temperature could increase enough to
turn the indicator off. To resolve a complaint of such
intermittent indications, confirm and clear the stored
DTC(s) and check the tire pressures. Then explain to the
client how temperature changes can affect the system.
