INSPECTION AND ADJUSTMENT
TRANSMITTER WAKE UP OPERATION
TRANSMITTER WAKE UP OPERATION : Description INFOID:0000000003579694
This procedure must be done after replacement of a transmitter, BCM, or rotation of wheels.
TRANSMITTER WAKE UP OPERATION : Special Repair Requirement INFOID:0000000003579695
1.TRANSMITTER WAKE UP OPERATION
1. With the transmitter activation tool (J-45295) pushed against the
front-left transmitter, press and hold the button 5 seconds.
SEIA0460E
2. When ignition switch ON, as the low tire pressure warning lamp blinks per the follow diagram, the respec-
tive transmitter then must be woken up.
SEIA0762E
3. Register the ID of wheel that low tire pressure warning lamp blinks. When wake up of registered wheel
has been completed, turn signal lamp blinks two times.
4. After completing wake up all transmitters, check that the low tire pressure warning lamp goes out.
>> Perform ID registration procedure. Refer to WT-6, "ID REGISTRATION PROCEDURE : Special
Repair Requirement".
ID REGISTRATION PROCEDURE
ID REGISTRATION PROCEDURE : Description INFOID:0000000003579696
This procedure must be done after replacing or rotating wheels, replacing transmitter or BCM.
ID REGISTRATION PROCEDURE : Special Repair Requirement INFOID:0000000003579697
1.ID REGISTRATION PREPARATION
1. Touch "WORK SUPPORT" on "SELECT DIAG MODE" screen, and select "ID REGIST".

System Description INFOID:0000000003579699
DESCRIPTION
During driving, the TPMS (Tire Pressure Monitoring System) receives the signal transmitted from transmitter
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.
