2. Remove the Tire – CAUTION: Do not damage the Wheel.

3. Remove the Tire Valve Stem (TPMS Unit) using a T-10 TORX Bit

4. Pull down the Wheel unit from valve stem. If needed use a standard TPMS Service Tool (available locally) and place a soft, scratch-resistant cloth on the wheel rim to prevent scratching/damage.

9. Install the Tire Valve Stems (Quantity= 4). If needed use a standard TPMS Service Tool and place a soft, scratch-resistant cloth on the wheel rim.

10. Verify the installation by checking the Distance between the Valve stem base and ensure there is no Gap where the Tire Valve Stem attaches to the wheel Groove and

CAUTION

  • A direct TPMS wheel unit has an exclusive valve cap. Always install the direct TPMS exclusive valve cap.
  • The wheel unit air pressure stem is made of aluminum and can be damaged. Do not tilt or use excessive side force when checking the air pressure or filling a tire with air. Some tire pressure gauges and air filling nozzles have extended tips, which could bend or break the air pressure stem of the wheel unit due to the added force they can apply.
  • Do not use a tire pressure gauge with an extended tip or air injector nozzle, because it will apply excessive force to the air pressure stem of the wheel unit.

PARTS AND WARRANTY INFORMATION
Recall Campaign 4721B

 

CONDITION OF CONCERN

On certain subject vehicles, the wheel and tire assembly may be equipped with a tire air valve having damage to the air valve sealing surface. If the affected tire air valve is installed, it is possible that an inflated tire may result in either a slow or sudden loss of air. A sudden air leak from the tire air valve may cause a loss of vehicle control while driving, increasing the risk of a crash.

A warning lamp and warning messages in the Multi-Information Display may notify the driver of a reduction in tire pressure if this defect occurs.

 

Causal factor:

Certain previously-installed and removed tire air valves might be mixed with new parts at the supplier due to improper isolation procedure. The previously-installed and removed tire air valve may have a damage on the sealing surface.

 

OUTLINE OF REPAIR

The tire air valves on all four wheel and tire assemblies will be replaced with new ones. Please refer to the Repair Procedure document on MGSS for further details.
