TIRE PRESSURE SENSOR WAKE UP OPERATION

Description

INFOID:0000000007544939

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

Work Procedure

INFOID:0000000007544940

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-18, "Work Procedure"

. 

NO

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

WT-22, "Diagnosis Procedure"

.

CAUTION:

To perform ID registration, observe the following points:

• Never register ID in a place where radio waves are interfered (e.g. radio tower).
• Never register ID in a place close to vehicles including TPMS.

With CONSULT.

1.

Display the “WORK SUPPORT” screen and select “ID REGIST”.

Is the tire pressure sensor activation tool (J-45295) used for the tire pressure sensor ID registration proce-
dure?

YES

>> GO TO 2.

NO

>> GO TO 3.

VATION TOOL)

1.

Turn the ignition switch ON.

2.

Select the start button on the “ID REGIST” screen.

3.

Contact the tire pressure sensor activation tool (J-45295) (1) to
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 

WT-39, "Diagnosis Procedure"

. 

3.

TIRE PRESSURE SENSOR ID REGISTRATION PROCEDURE (WITHOUT TIRE PRESSURE SENSOR

ACTIVATION TOOL) 

1.

Adjust the tire pressure for all wheels to match the list below.

TIRE PRESSURE MONITORING SYSTEM OPERATION

With CONSULT

1.

Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.

2.

On “DATA MONITOR”, select “AIR PRESS FL”, “AIR PRESS FR”, “AIR PRESS RR” and “AIR PRESS
RL”, and check that the tire pressures match the standard value.

CAUTION:

Stop the vehicle and within 5 minutes, use CONSULT “DATA MONITOR” to display the tire pressure for
all wheels.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Perform trouble diagnosis. Refer to 

WT-29, "Diagnosis Procedure"

.
