49.) A technician is replacing tires on a vehicle equipped with tire pressure monitoring system (TPMS)sensors mounted on the valve stems. Technician A says that when using the tire changer shovel to break the bead loose from the wheel, the valve stem should be positioned approximately 90^circ from the shovel. Technician B says that after the tire and wheel assemblies are installed on the vehicle, running a TPMS relearn procedure may be required. Who is right? 4. A only OB. B only OC. Both A and B OD.

## Step 1This problem is about the Tire Pressure Monitoring System (TPMS) in vehicles. TPMS is a system that monitors tire pressure and alerts the driver if the pressure in any tire falls below or exceeds the recommended level. The system is equipped with sensors that are usually located on the valve stems of the tires.## Step 2Technician A suggests that when using the tire changer shovel to break the bead loose from the wheel, the valve stem should be positioned approximately 90 degrees from the shovel. This is a correct procedure as it ensures that the valve stem is not damaged during the tire changing process.## Step 3Technician B suggests that after the tire and wheel assemblies are installed on the vehicle, running a TPMS relearn procedure may be required. This is also a correct procedure as it allows the TPMS to recognize the new tire and wheel assembly and adjust the tire pressure accordingly.
