NOTE:
If transmitter wake-up operation is not completed for tw o or more transmitters, the applicable 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 LH wheel and
rear RH wheel transmitters.)
Low tire
pressure
warning
lamp The low tire pressure
warning lamp repeats
blinking at 0.5-second
intervals for 1 minute,
and then stays illumi-
nated. 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 low tire pr essure warn-
ing control unit harness
connector is removed. Check the connection con-
ditions of the low tire pres-
sure warning
control unit
harness connector, and re-
pair if necessary.
Tire Pressure Monitoring
System (TPMS) malfunc-
tion.  Perform self-diagnosis.
- If necessary, perform
transmitter ID registra-
tion. Refer to WT-29,
"Work Procedure".
Hazard
warning
lamp The hazard warning
lamp does not blink
twice when the trans-
mitter is activated.
— The transmitter activation
tool does not activate.  Replace the battery in the
transmitter activation
tool.
 The ignition switch is OFF when the transmitter
wake-up operation is per-
formed.  Turn the ignition switch
ON when performing the
transmitter wake-up op-
eration.
 The transmitter activation tool is not used in the cor-
rect position.  Operate the transmitter
activation tool in the cor-
rect position when per-
forming the wake-up
operation.
 The transmitter is already waked up.  No procedure.
