TPMS Transmitter

REMOVAL AND INSTALLATION

WARNING Certain components of this vehicles, such as TPMS transmitters, may contain perchlorate materials. Special handling may apply. For additional information, see www.dtsc.ca.gov/hazardouswaste/ perchlorate.

CAUTION

• Ensure valve cap is always in place except when adjusting tire pressure.
• If the valve core and valve cap are replaced, use a genuine replacement part. The valve core is similar to a conventional one, but uses nickel plating to avoid corrosion.
• Replace the seal washer with a new one when the tire is replaced.
• Do not drop the TPMS transmitter from height greater than 1 meter (3.3 feet).
• Do not expose the TPMS transmitter to extraneous magnetic fields.
• TPMS transmitter should not be stored at temperatures above 80ºC (176ºF).
• TPMS transmitter should not be exposed to temperatures above 100ºC (212ºF).
• If the TPMS transmitter is replaced, execute "Tire Pressure Sensor ID Registration" on scan tool MB991958 "Special Function".
• Be careful not to damage the TPMS transmitter.

Pre-removal Operation

REMOVAL SERVICE POINTS

CAP/VALVE CORE/NUT REMOVAL

CAUTION Ensure cap is always in place except when adjusting tire pressure.

1. Remove the valve cap.

2. Rotate tire so that valve stem is in the 6 o'clock position.

3. Use a long-reach 17.2 mm (0.68 inch) socket to unscrew the valve nut a few turns. Slowly push valve stem into tire so that tire pressure is relieved.

4. Once tire pressure is released, remove nut and let TPMS transmitter fall into tire.

TPMS TRANSMITTER REMOVAL

CAUTION Be careful not to damage the TPMS transmitter.

1. Place on tire changing machine and break both tire beads ensuring that the TPMS transmitter remains in the bottom of the tire.

2. Lubricate tire well and remove outer side of the tire.

3. Reach inside the tire and remove the TPMS transmitter.

4. Remove tire from rim using proper tire changing equipment procedures.

SEAL WASHER/VALVE REMOVAL

CAUTION Remove the seal washer to prevent scratching the valve of the TPMS transmitter.

1. Hold the TPMS transmitter and the seal washer, then extract the seal washer. Take care to not damage the valve thread.

2. Clean the TPMS transmitter and the valve stem. <In case of not removing the valve>

NOTE: If the valve comes out from the transmitter, install it to where it was. (This is not failure)

3. Removal the valve from housing as shown.

INSTALLATION SERVICE POINTS

VALVE/SEAL WASHER/TPMS TRANSMITTER/ NUT INSTALLATION

CAUTION Install the seal washer to prevent scratching the valve of the TPMS transmitter.

1. Install the valve to housing as shown.

2. Insert the seal washer up to the base of the TPMS transmitter, making sure to secure the valve base with a thumb as shown.

Wipe the seal and threading.

CAUTION

• Visually check that TPMS transmitter is not deformed or damaged.
• When installing the TPMS transmitter, be sure the rim, seal valve and nut are clean.
• Ensure the grommet is located inside the valve hole before installing the nut.
• While installing the nut, push the TPMS transmitter to maintain the lower lip of the transmitter case is in contact with the rim without clearance.
• While installing the valve nut, ensure the tool is kept aligned to the valve and the valve hole.

3. Install the valve, in the valve hole, without modifying the angle of the stem (retain position of delivery). The laser marking should be visible at the operator.

4. When the valve is completely inserted, maintain the TPMS transmitter in contact with the rim, then screw manually the nut until the contact with the wheel.

5. While maintaining the TPMS transmitter contact with the rim by applying pressure to the back of the valve, slightly press on the cap to wards the center of the wheel in order to adapt the angle of the valve/TPMS transmitter to the profile of the rim.

It is mandatory to guarantee the contact of the housing unit on the rim drop center.

6. While maintaining the TPMS transmitter and valve in position, screw the nut with a torque wrench.

Take care that the wrench socket is correctly inserted on the nut.

Specified torque: 8.0 +- 0.5 N*m (71 +- 4 in-lb)

TIRE BEAD MOUNTING

1. Prepare the tire and fix the rim as usual.

2. Put the tire on the rim, so that the cross point of the belt with the rim is approximately 20 cm (7.9 inch) away from the valve.

3. Engage the shoe and make sure that 20 cm (7.9 inch) is maintained between the cross point and the valve.

The arrow shows the direction of rotation of the wheel.

4. Turn the wheel in order to engage all the first side of the tire.

NOTE: The standard shoes can pass over the sensor without damaging it.

5. Put the second side of the tire in position, so that the cross point of the belt with the rim is approximately 20 cm (7.9 inch) away from the valve. The curved arrow shows the direction of rotation of the wheel.

6. Turn the wheel in order to engage all of the second side of the tire.

NOTE: The standard shoes can pass over the sensor without damaging it.

TIRE PRESSURE INFLATION/NUT RETIGHTENING

CAUTION After tire inflation, retighten the valve nut to 8.0 +- 0.5 N*m (71 +- 4 in-lb). This is necessary, because the TPMS transmitter is secured to the wheel with the valve nut and rubber grommet. The rubber grommet will be depressed by tire pressure or deteriorate over a period of time, which requires the valve nut to be retightened.

Inflate tire to required pressure, then retorque the valve nut to 8.0 +- 0.5 N*m (71 +- 4 in-lb).
