Tire Mounting And Dismounting Procedures When Equipped With Tire Pressure Monitoring System (TPMS)

Issue Date: March, 2004

Affected Vehicles

2004 Rodeo (UE) models equipped with TPMS sensor.

Service Information





Isuzu has introduced the Tire Pressure Monitoring System (TPMS) for some 2004 Rodeo (UE) models. This system utilizes a sensor permanently affixed to the valve stem and mounted in each wheel to detect tire pressure, see figure 1 shows sensor component identification.

Service Procedure

The following steps illustrate the correct tire mounting and dismounting procedure.

NOTE:
^ Use caution to avoid damaging the TPMS sensor when dismounting or mounting the tire and removing or installing the TPMS sensor.

^ Failure to follow these procedures will result in a damaged TPMS sensor.





1. Release the air pressure from the tire and remove the TPMS Sensor retaining nut using a 12 mm thin-wall socket (see figure 2), the TPMS sensor will drop inside the tire.

NOTE:
To avoid damaging the TPMS sensor, DO NOT use a wrench to remove or install the TPMS sensor-retaining nut.





2. Using a tire changer break the outer tire bead (see figure 3) and inner tire bead (see figure 4).

NOTE:
Avoid damaging the TPMS sensor, as it now located at the bottom of the tire.





3. Place the tire on the changer's clamping table and remove the outer tire bead (see figure 5). When the tire's outer bead has been removed, locate the TPMS sensor inside the tire and remove it. If the tire is being replaced, dismount the tire completely.





4. Apply a minimal amount of tire-mounting lubricant on the inner and outer tire beads and mount (see figure 6).

NOTE:
Applying excessive tire mounting lubricant may damage the TPMS sensor or cause bead slippage.

5. Insert the TPMS Sensor into the valve stem hole with the flat side facing the wheel. Ensure the TPMS Sensor rubber grommet has made proper contact with the wheel surface.





NOTE:
Tire has been removed for illustration purposes only (see figure 7).

When installing the TPMS Sensor the tire may need to be physically maneuvered to create adequate working space (see figure 8).





NOTE:
A correctly positioned TPMS Sensor will not have interference between the sensor body and wheel (see figures 7-10).





6. Secure the TPMS Sensor to the wheel using the retaining nut, verify the TPMS Sensor grommet is positioned correctly. Hand screw the retaining nut and torque to 7.5 +/- 1.5 N.m (66 +/- 13 in. lb.) (see figure 11).

7. Inflate the tire according to the vehicles certification label located on the drivers door lock pillar. Avoid the tire bead coming in contact with the TPMS Sensor when seating the bead.

NOTE:
Proper tire inflation is critical to avoid reoccurring TPMS warning lamp illumination.
