INFOID:0000000008462627

This procedure must be done after replacement of a tire pressure sensor, BCM, or rotation of wheels.

Work Procedure

INFOID:0000000008462628

1.

TIRE PRESSURE SENSOR WAKE-UP PROCEDURE

1.

Turn the ignition switch ON.

CAUTION:

Never start the engine.
NOTE:
The position of an inactive tire pressure sensor can be identified by checking the blinking timing of the low
tire pressure warning lamp.

2.

Contact the tire pressure sensor activation tool (J-45295) (1) to
the side of the tire at the location to the tire pressure sensor.

3.

Press and hold the tire pressure sensor activation tool button
while pushing the tool to the tire surface. (approximately for 5
seconds)

CAUTION:

Perform the wake-up procedure starting from the vehicle
front left wheel, then repeat the procedure in the order of
the front right wheel, rear right wheel, and rear left wheel.

4.

Check that the turn signal lamps blink twice when the tire pres-
sure sensor wake-up procedure for all wheels is completed.

5.

Check that the low tire pressure warning lamp turns OFF, after
the tire pressure sensor wake-up procedure is completed for all wheels and turns OFF.

Is the tire pressure sensor wake-up procedure completed?

YES

>> Perform the tire pressure sensor ID registration procedure. Refer to 

WT-19, "Work Procedure"

. 

NO

>> Perform trouble diagnosis for the tire pressure sensor. Refer to 

WT-23, "Diagnosis Procedure"

the side of the tire at the location to the tire pressure sensor.

4.

Press and hold the tire pressure sensor activation tool button
while pushing the tool to the tire surface. (approximately for 5
seconds)

CAUTION:

Perform the ID registration procedure starting from the
vehicle front left wheel, then repeat the procedure in the
order of the front right wheel, rear right wheel, and rear left
wheel.

5.

When ID registration is completed, check the following pattern at each wheel.

6.

After the ID registration procedure for all wheels is completed, press “END” to end ID registration, and
check that ID registration for all wheels is completed.

Is the check result normal?

YES

>> ID registration END.

NO

>> Refer to
