Cause

Action

Low tire pres-

lamp

The low tire pres-
sure warning lamp
illuminates for 1
second, then turns
OFF.

Wake-up operation for all
tire pressure sensors at
wheels is completed.

No system malfunctions

The low tire pres-
sure warning lamp
turns ON and stays
illuminated.

Low tire pressure

Check the tire pressure for
all wheels and adjust to the
specified value. Refer to

WT-66, "Tire Air Pressure"

.

Tire pressure monitoring
system configuration do
not be performed.

Perform configuration. Re-
fer to

WT-30, "Work Proce-

dure"

.

Tire pressure sensor ID
registration do not be
performed.

Perform ID registration. Re-
fer to

WT-29, "Work Proce-

dure"

.

The low tire pres-
sure warning lamp
repeats blinking at
0.5-second inter-
vals for 1 minute,
and then stays illu-
minated.

The BCM cannot detect
tire pressure data signal.

• Check visually that the

tire pressure sensors are
installed. If necessary, re-
place/install the tire pres-
sure sensor(s) and
perform tire pressure
sensor ID registration.
Refer to

WT-29, "Work

Procedure"

.

• Remove the interference

radio wave (e.g. battery
charger of smart phone).

The combination meter
fuse is open or removed
(or pulled out).

Check the connection con-
ditions of the BCM harness
connector, and repair if nec-
essary.
