A << Grommet/Washer/TPMS Transmitter/Valve Nut Installation

CAUTION: When installing a new grommet and washer, make sure to support the valve stem base with a thumb so that there is no movement of the stem. Otherwise, the stem may protrude resulting in the breakage of antenna plate.

Install a new grommet and washer to the TPMS transmitter.
CAUTION:
- Visually check that TPMS transmitter is not deformed or damaged.
- When installing the TPMS transmitter, be sure the rim, grommet and valve nut are clean.
- Ensure the grommet is located inside the valve hole before installing the valve nut.
- While installing the valve nut, push the 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.
- After installing the valve nut, check that the grommet is compressed and washer is bend.
