Transmitter Wake Up OperationEES002EZ
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.Tool number : (J-45295)

BASIC INSPECTION
1. CHECK ALL TIRE PRESSURES
Check all tire pressures. Refer to WT-29, "
Tire" .
OK or NG
OK >> GO TO 2.
NG >> Adjust tire pressure to specified value.
2. CHECK LOW TIRE PRESSURE WARNING LAMP ACTIVATION
Check low tire pressure warning lamp activation.
Does warning lamp activate for 1 second when ignition switch is turned ON?
YES >> GO TO 3.
NO >> GO TO WT-23, "
Low Tire Pressure Warning Lamp Does Not Come On When Ignition Switch Is
Tu rne d On." .
3. CHECK BCM CONNECTOR
1. Disconnect BCM harness connector.
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK TRANSMITTER ACTIVATION TOOL
Check transmitter activation tool battery.
OK or NG
OK >> Carry out self-diagnosis.
NG >> Replace battery in transmitter activation tool.
Self-DiagnosisEES002F1
DESCRIPTION
During driving, the low tire pressure warning 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 low tire pressure warning 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.
