INSPECTION AND ADJUSTMENT

Preliminary Check

INFOID:0000000001277801

1.

TIRE PRESSURE

Check all tire pressures. Refer to 

WT-40, "Tire"

.

Do tire pressures match specification?

YES

>> GO TO 2.

NO

>> Adjust tire pressures to specified value.

2.

LOW TIRE PRESSURE WARNING LAMP

Check low tire pressure warning lamp activation.
Does the low tire pressure warning lamp activate for one second when ignition switch is turned ON?

YES

>> GO TO 3.

NO

>> GO TO 

WT-25, "Low Tire Pressure Warning Lamp Does Not Come On When Ignition Switch Is

Turned On"

.

3.

BCM CONNECTOR

1.

Disconnect BCM harness connectors.

2.

Check terminals for damage or loose connections. 

3.

Reconnect harness connectors.

Are BCM connectors damaged or loose?

YES

>> Repair or replace damaged parts.

NO

>> GO TO 4.

4.

TRANSMITTER ACTIVATION TOOL

Check battery in transmitter activation tool.

Is transmitter activation tool battery fully charged?

YES

>> Perform self-diagnosis.  Refer to 

WT-21, "Self-Diagnosis"

.

NO

>> Replace battery in transmitter activation tool.

Transmitter Wake Up Operation

INFOID:0000000001277802

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 Acti-
vation 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 following
diagram.

2.

Repeat this procedure for each tire in the following order: FL, FR, RR, RL.

INSPECTION AND ADJUSTMENT

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.

ID Registration Procedure

INFOID:0000000001277803

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 Acti-
vation Tool J-45295 before ID registration can be performed.
1.

Connect CONSULT-III.

2.

Select ID REGIST under BCM.

3.

Push the transmitter activation tool against the tire near the front
left transmitter. Press the button for 5 seconds.

4.

Register the IDs in order from FR LH, FR RH, RR RH and RR LH. When ID registration of each wheel has
been completed, the hazard warning lamps flash.

5.

After completing all ID registrations, press END to complete the procedure.

NOTE:
Be sure to register all of the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results
display will not function properly.

System Description

INFOID:0000000001277829

BODY CONTROL MODULE (BCM)

The BCM (1) is shown with the lower instrument panel LH removed.
The BCM reads the air pressure signal received by the remote key-
less entry receiver, and controls the low tire pressure warning lamp
as shown below. It also has a self-diagnosis function to detect a sys-
tem malfunction.

TRANSMITTER

A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pressure signal in the form of a
radio wave.  The radio signal is received by the remote keyless entry
receiver.
