ID Registration ProcedureINFOID:0000000001327582
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacemen t of a transmitter, BCM or rotating wheels.
1. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
2. With the transmitter activati on tool (J-45295) pushed against the
front-left transmitter position of the air valve, press and hold the
button 5 seconds.
3. Register the IDs in order from FR LH, FR RH, RR RH to RR LH. When ID registration of each wheel has been completed, turn
signal lamp blinks.
4. After completing all ID registrations, press “END” to complete the procedure.
NOTE:
Be sure to register the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results dis-
play will not function properly.
ID Registration without Tr ansmitter Activation Tool
CAUTION:
This procedure must be done after replacement of a transmitter, BCM, or rotating wheels.
1. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
2. Adjust the tire pressure to the values shown in t he table below for ID registration, and drive the vehicle at
40 km/h (25 MPH) or more for several minutes.
NOTE:
If ID registration is unable, buzzer beeps.
3. After completing all ID registrations, press “END” to complete the procedure.

Transmitter Wake Up OperationINFOID:0000000001327583
W I T H A C T I VAT I O N T O O L
1. With the transmitter activation tool (J-45295) pushed against the
front-left transmitter, press the button for 5 seconds.
 When ignition switch ON, as the low tire pressure warninglamp blinks per the following diagram, the respective transmit-
ter then must be woken up.
2. Register the ID of wheel that low tire pressure warning lamp flashes. When wake up of registered wheel
has been completed, turn signal lamp flashes two times.
3. After completing wake up all transmitters, make sure low tire pressure warning lamp goes out.
Self-DiagnosisINFOID:0000000001327584
DESCRIPTION
During driving, the low tire pressure warning syste m receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) of this
system has pressure judgment and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground terminal
of the tire pressure warning check connector. The malf unction location is indicated by the warning lamp flash-
ing and the buzzer sounds.

NOTE:
If more than one wheel transmitter is NOT activated, the warning lamp blinking patterns for those wheels will combine. (Example: one
blink/OFF/three blinks = Rear LH and Rear RH transmitters are not activated.)
