DESCRIPTION and OPERATION
During driving, the TPMS system receives the signal transmitted from the tire pressure sensor installed in each wheel. The body control module (BCM) of this system has pressure judgment and trouble diagnosis functions. When the TPMS system detects low inflation pressure or another unusual symptom, the low tire pressure warning lamp in the combination meter comes on.
Tire pressure varies as per the change in tire temperature. If the tire pressure is less than the warning tire pressure value, the low tire pressure warning lamp illuminates.
Location of wheel is specified due to the synchronism of wheel sensor position and tire pressure sensor position.
The TPMS system is activated when the vehicle speed is 25 mph (40 km/h) or more.
The TPMS system has Easy Fill Tire Alert function to aid in tire inflation.
ID REGISTRATION PROCEDURE

TPMS ID registration can be performed using one of the following procedures:
- Transmitter Activation tool [KV48105501 (J-45295-A) ] using CONSULT (preferred method)
- Signal Tech II tool [- (J-50190) ] using CONSULT (preferred method)
- Signal Tech II tool [- (J-50190) ] without CONSULT
- CONSULT only
TPMS REGISTRATION WITH TRANSMITTER ACTIVATION TOOL — KV48105501 (J-45295-A)
1.) Ignition switch ON.
2.) Select "Work support" mode of "BCM (AIR PRESSURE MONITOR). " Then, select "ID REGIST."
3.) Select "Start" on "ID REGIST" screen.
4.) Hold the transmitter activation tool, KV48105501 (J-45295-A), against the side of the left front tire, near the valve stem.
5.) With the tool held at a 0 to 15 degree angle to the tire, press and hold the transmitter activation tool button until the indicator lamp turns OFF (approximately five seconds).
6.) Repeat steps four and five for the remaining tires in this order: right front, right rear and left rear.
7.) When ID registration is complete, check the following pattern at each wheel: Front LH, Front RH, Rear RH, Rear LH. (Two blinks of the turn signal lamp. Green on CONSULT indicates done.)
8) After the ID registration procedure for all wheels is complete, select "End" to finish ID registration.
9) Test drive the vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
TPMS REGISTRATION WITH SIGNAL TECH II TOOL — J-50190
1.) Adjust the tire pressure for all tires to the recommended value.
2.) Ignition switch ON.
3.) Select "Work support" mode of "BCM (AIR PRESSURE MONITOR). " Then, select "ID REGIST."
4.) Select "Start" on "ID REGIST" screen.
5.) Turn on the Signal Tech II tool (J-50190).
6.) Hold the Signal Tech II against the side of the left front tire, near the valve stem.
7.) With the tool held at a 0 to 15 degree angle to the tire, select "Activate Sensor" from the main menu, then press and release the "OK" button to activate the sensor. Once the sensor is activated, the vehicle parking lamps will flash and the sensor ID will appear on the CONSULT screen.
8.) Repeat steps 6 and 7 for the remaining tires in this order: right front, right rear and left rear.
9.) When ID registration is complete, check the following pattern at each wheel: Front LH, Front RH, Rear RH, Rear LH.
10.) Once all sensors have been activated, select "End" to finish ID registration.

TPMS Registration With Signal Tech II Tool (J-50190) without CONSULT
1.) Adjust the tire pressure for all tires to the recommended value.
2.) Turn on the Signal Tech II tool (J-50190) and select "TPMS Check" from the main menu.
3.) Select vehicle model and year.
4.) When prompted, hold the Signal Tech II against the side of the left front tire, near the valve stem.
5.) With the tool held at a 0 to 15 degree angle to the tire, press and release the "OK" button to activate the sensor. Once the sensor is activated, the tool will sound a tone and the tire pressure will be displayed.
6) Repeat steps four and five for the remaining tires in this order: right front, right rear and left rear.
7) When prompted, connect the tool to the data link connector. The tool will connect to the BCM, read the VIN, read sensor IDs and check for TPMS DTCs. Along with DTCs detected, one of the following will be displayed next to each wheel:
- N/A - Not applicable because no ID found by the tool
- OK - Wheel and sensor are in original position
- NEW - New ID found compared to BCM
- RT - Wheel has been rotated
- Low Press - Low tire pressure
8.) If no DTC is present or the repair has been completed, press the "OK" button to register the IDs and clear DTCs.

TIRE PRESSURE SENSOR REMOVAL AND INSTALLATION
WHEEL AND TIRE
Removal and Installation
REMOVAL
1.) Remove wheel cover (if equipped).
2.) Remove wheel nuts using power tool.
3.) Remove wheel and tire.
CAUTION:
- When installing wheel nuts, tighten them diagonally by dividing the work two or three times in order to prevent the wheels from developing any distortion.
- Be careful not to tighten wheel nuts to a torque exceeding the specification to prevent strain on the disc brake rotor or brake drum.
