Diagnostic Steps

1
Scan the vehicle's computer using an OBD-II scanner to retrieve any diagnostic trouble codes (DTCs) related to the TPMS.
2
Visually inspect all tires for visible damage, leaks, or signs of incorrect inflation.
3
Check the tire pressure in all four tires to ensure they are within the manufacturer's recommended levels.
4
Inspect the TPMS sensors for physical damage or corrosion, especially at the valve stems.
5
Verify the battery condition of the TPMS sensors if applicable, as low battery power can affect performance.

Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, TPMS reset tool, jack, jack stands, and tire iron.
Ensure the vehicle is parked on a level surface and turned off. Engage the parking brake.

2. Tire Inspection and Repair

Sub-steps:
1. Remove the valve caps from each tire and check the tire pressure using a tire pressure gauge.
2. Inflate or deflate tires as necessary to match the recommended PSI found on the driver’s door jamb sticker.
3. Inspect for any punctures or damage; repair or replace tires if necessary.

3. TPMS Sensor Check

Sub-steps:
1. If any tire is being replaced or serviced, ensure the TPMS sensor is properly installed and functional.
2. If damaged, remove the tire from the wheel to access the sensor.
3. Replace the TPMS sensor if damaged or if the battery is dead, following the manufacturer’s guidelines.

4. TPMS Reset

Sub-steps:
1. With all tires properly inflated, turn the ignition to the "ON" position without starting the engine.
2. Press the TPMS reset button (usually located beneath the steering wheel or in the glove compartment) until the TPMS light blinks three times, then release it.
3. Drive the vehicle for about 10 minutes at speeds above 25 mph to allow the system to recalibrate.
