NOTICE:
• The transmitter ID is written on the tire
pressure warning valve and
transmitter. It will be unable to be read
after installing the tire pressure
warning valve and transmitter on the
tire and wheel. Therefore, take a note
of the transmitter ID before installing
the tire pressure warning valve and
transmitter.
• The ID registration must be performed
for all tire pressure warning valve and
transmitters. Check the DATA LIST,
replace the exchanged ID with a new
ID, and make a new data list of all 4
tires for the vehicle.
2. REGISTER TRANSMITTER ID (Using Intelligent
Te s t e r )
(a) Connect the intelligent tester to DLC3 (Procedure
"A").
(b) Turn the ignition switch to the ON position
(Procedure "B").
(c) Select the REGIST TIRE following the intelligent
tester screen (UTILITY - REGIST TIRE) (Procedure
"C").
(d) Input the IDs (ID1 to ID4) using the intelligent tester
and transmit them to the tire pressure warning ECU
(Procedure "D").
(e) Set the ID transmission condition to "ID Registration
is complete" (Procedure "E").
HINT:
• The previously registered IDs will be deleted
from the memory when the registration is
completed.
• If the procedures "C" to "D" are not completed
within 5 min., the mode will return to the normal
operation mode.
• If the registration cannot be completed with error,
connect TC to GND of DLC3, then retry.
• When the system is in initialization mode after
the tire pressure warning reset switch has been
operated, the registration is disabled until the
initialization process is canceled or completed.

INITIALIZATION
1. DESCRIPTION OF INITIALIZATION
(a) Perform initialization in the following cases:
• Before delivery of a new vehicle.
• After replacement of the tire pressure warning
ECU*.
• After replacement of the tire pressure warning
valve and transmitter.
• Specified tire pressure changes depending on
the size or type of the tire.
*: Perform initialization after the transmitter ID
registration is completed (See page TW-20).
(b) Before initialization
(1) Set the air pressure of all tires to the specified
value.
Cold tire inflation pressure
NOTICE:
Perform the tire pressure adjustment after
the vehicle has sufficiently cooled down. If
the vehicle is not sufficiently cooled down,
increase the air pressure by 20 to 30 kPa (0.2
to 0.3 kgf/cm
2, 2.9 to 4.3 psi) above the
specified value.

4. SPEED SENSOR SIGNAL CHECK (WHEN USING
INTELLIGENT TESTER):
HINT:
• If the ignition switch is turned from the ON to the ACC
or LOCK position during Test Mode, DTCs of the
signal check function will be erased.
• During Test Mode, the ECU records all DTCs of the
signal check function. By performing the signal check,
the codes are erased if normality is confirmed. The
remaining codes are the codes where an abnormality
was found.
(a) Turn the ignition switch off.
(b) Check that the steering wheel is in the straight-
ahead position.
(c) Connect the intelligent tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Set the intelligent tester to Test Mode (select
"SIGNAL CHECK").

BRAKE CONTROL – ANTI-LOCK BRAKE SYSTEMBC–19
BC
DESCRIPTION
The speed sensor detects wheel speed and transmits the appropriate signals to the ECU. These signals
are used for control of the ABS control system. The front and rear rotors have 48 serrations each.
When the rotors rotate, the magnetic field generated by the permanent magnet in the speed sensor
induces an AC voltage.
Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the
frequency is used by the ECU to detect the speed of each wheel.
DTCs C1271/71 to C1276/76 can be deleted when the speed sensor sends a vehicle speed signal or the
Test Mode ends. DTCs C1271/71 to C1276/76 are output only in the Test Mode.
