TPMS TRANSMITTER
REMOVAL AND INSTALLATION
M1427509300017
CAUTION
• Do not vary the angle of valve except at mounting on the rim. If varying the angle over and over, it
may cause breakage of antenna plate resulting in the failure of TPMS transmitter.
• 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 and seal washer with a new one every five years or 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 80° C (176° F).
• TPMS transmitter should not be exposed to temperatures above 100° C (212° F).
• 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.
