ID Registration ProcedureINFOID:0000000001703756
ID REGISTRATION WITH TRANSMITTER ACTIVATION TOOL
NOTE:
This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter
Activation Tool J-45295 before ID registration can be performed.
1. Connect CONSULT-III.
2. Select “AIR PRESSURE MONITOR” on "SELECT TEST ITEM" screen.
3. Select “WORK SUPPORT” on "SELECT DIAG MODE" screen, and select "ID REGIST".
4. Push the transmitter activation tool against the tire near the front
left transmitter. Press the button for 5 seconds.
5. Register the IDs in order from FR LH, FR RH, RR RH and RR LH. When ID registration of each wheel has
been completed, a buzzer sounds and the hazard warning lamps flash.
6. 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.

Transmitter Wake Up OperationINFOID:0000000001703757
NOTE:
This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter
Activation Tool J-45295 before ID registration can be performed.
1. Turn ignition switch ON. Push the transmitter activation tool
against the tire near the front left transmitter. Press the button for
5 seconds.  The hazard warning lamps flash per the diagram
below.
2. Repeat this procedure for each tire in the following order: FL, FR, RR, RL.
3. When the BCM finishes assigning each tire ID, the BCM flashes the hazard warning lamps and sends
flashing indicator status by CAN according to the following time chart.
4. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.

How to Perform Trouble Diagnosis for Quick and Accurate RepairINFOID:0000000001703759
INTRODUCTION
• Before troubleshooting, verify customer complaints.
• If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
functioning. Hold and shake these parts to make sure they are securely connected.
• When using a circuit tester to measure voltage or resistance of each circuit, be careful not to damage or
deform connector terminals.

Self-DiagnosisINFOID:0000000001703761
DESCRIPTION
During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter
installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.
The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.
FUNCTION
When the tire pressure monitoring system detects low inflation pressure or an internal malfunction, the low tire
pressure warning lamp in the combination meter comes on. The malfunction location is indicated by the low
tire pressure warning lamp flashing and the buzzer sounding.
