CAUTIONS DURING TPMS (TIRE PRESSURE MONITORING SYSTEM) WHEEL SENSOR SERVICE
DESCRIPTION:
This bulletin provides service procedures that help protect TPMS wheel sensors from service-related damage.
Case # 1: TPMS valve stem breakage
The valve stem may break during tire inflation or deflation while using a long air-filling nozzle tube as shown.
Case # 2: TPMS valve stem bursts
CAUTION:
DO NOT reuse the valve core if it has been removed. If the valve core has been removed, install only a NON BRASS type valve core as a replacement.
Cautions during TPMS sensor removal and installation:
1. Removal:
^ Start unseating the tire bead about 6 inches (15cm) from the TPMS valve stem.
^ Make sure that the tool does not touch the TPMS sensor while unseating the tire bead.
^ When unfastening the TPMS sensor, hold it securely without rocking.
2. Installation:
^ Do not exceed the allowed torque and DO NOT use electric or pneumatic tools. Tightening torque = 3.0 lb. ft. (4 Nm, 0.4 Kg. m)
^ Attach the sensor to the rim firmly.
^ Hold the sensor and assemble the valve stem to the sensor by hand.
^ Secure the TPMS sensor by rotating the valve stem clockwise with a torque wrench.
^ After installing the TPMS sensor, check if it is attached to the rim firmly.
^ Start seating the tire bead about 15cm (6 inches) from the TPMS valve stem.
^ Make sure that the tool does not touch the TPMS sensor while seating the tire bead.
