tire pressure sensors at
wheels is completed.

No system malfunctions

The low tire pres-
sure warning lamp
repeats blinking
ON for 2 seconds
and OFF for 0.2
seconds.

Wake-up operation for all
tire pressure sensors at
wheels is not completed.

Perform the wake-up oper-
ation for all tire pressure
sensors at wheels. Refer to

WT-23, "Work Procedure"

.

The low tire pres-
sure warning lamp
blinks once.

The front left tire pres-
sure sensor is not acti-
vated.

Perform the wake-up oper-
ation for the tire pressure
sensor at front left wheel.

sure warning lamp
repeats blinking
twice.

The front right tire pres-
sure sensor is not acti-
vated.

Perform the wake-up oper-
ation for the tire pressure
sensor at front right wheel.
Refer to

WT-23, "Work Pro-

cedure"

.

The low tire pres-
sure warning lamp
repeats blinking for
3 times.

The rear right tire pres-
sure sensor is not acti-
vated.

Perform the wake-up oper-
ation for the tire pressure
sensor at rear right wheel.
Refer to

TPMS

NOTE:
If tire pressure sensor wake-up operation is not completed for two or more tire pressure sensors, the applica-
ble low tire pressure warning lamp blinking patterns are displayed continuously.
(Example: Blinks once/OFF/blinks 3 times = Wake-up operation is not completed at the front left wheel and
rear right wheel tire pressure sensors.)

Low tire pres-
sure warning
lamp

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

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

Check and install the com-
bination meter fuse. If nec-
essary, replace the fuse.

The BCM harness con-
nector is removed.

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

Tire Pressure Monitoring
System (TPMS) mal-
function.

• Perform CONSULT self-

diagnosis. Refer to

WT-9,

"COMMON ITEM : CON-
SULT Function (BCM -
COMMON ITEM)"

(With

intelligent key system),

WT-13, "COMMON ITEM
: CONSULT Function
(BCM - COMMON
ITEM)"

(Without intelli-

gent key system).

• If necessary, perform tire

pressure sensor ID regis-
tration. Refer to

WT-24,

"Work Procedure"

.

Turn signal
lamp

The turn signal
lamps do not blink
twice when the tire
pressure sensor is
activated. Or the
