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

This procedure must be done after replacement of a tire pressure sensor, BCM, or rotation of wheels.
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
NO
>> Perform trouble diagnosis for the tire pressure sensor. Refer to
