System Description

INFOID:0000000007565870

During driving, the TPMS (Tire Pressure Monitoring System) receives the signal transmitted from tire pressure
sensor installed in each wheel. The BCM (Body Control Module) of this system has pressure judgment and
trouble diagnosis functions. When the tire pressure monitoring system detects low inflation pressure or
another unusual symptom, the low tire pressure warning lamps in the combination meter comes on.

SYSTEM DIAGRAM

INPUT/OUTPUT SIGNAL

The signal transmission/reception between units via a communication line is mainly as listed in the following
table.

LOW TIRE PRESSURE WARNING LAMP INDICATION CONDITION

Uses CAN communication from the BCM to illuminate the low tire pressure warning lamp on the combination
meter.

JSEIA0157GB

Component parts

Signal item

BCM

Transmits the following signals via CAN communication to combination meter.
• Low tire pressure warning lamp signal
• TPMS malfunction warning lamp signal

Combination meter

Transmits the vehicle speed signal via CAN communication to BCM.

Condition

Work Procedure

INFOID:0000000007565879

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

1.

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.
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.

2.

TIRE PRESSURE SENSOR ID REGISTRATION PROCEDURE (WITH TIRE PRESSURE SENSOR ACTI-

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
