Diagnostic Steps

1
Inspect each tire visually for signs of damage, punctures, or low pressure.
2
Use a tire pressure gauge to check the pressure of all four tires, including the spare if equipped.
3
Examine the tire pressure monitoring system (TPMS) for any error codes using an OBD-II scanner.
4
Verify that the TPMS sensors are functioning and not damaged.
5
Check the vehicle’s manual for any specific reset procedures related to the TPMS.

Solution

1. Preparation

Gather the necessary tools: tire pressure gauge, OBD-II scanner, and a jack with jack stands.
Ensure the vehicle is parked on a flat surface and the tires are cold for accurate pressure readings.

2. Tire Inspection

Check each tire: Inspect for punctures, cuts, or bulges.
Inflate tires: If any tire is low, inflate it to the manufacturer's recommended pressure (found on the driver’s door jamb).
Replace damaged tires: If any tire is beyond repair, replace it with a new tire.

3. TPMS Check

Scan TPMS: Connect the OBD-II scanner to the vehicle’s diagnostic port and check for any TPMS-related error codes.
Replace batteries: If the sensors are not responding, replace the batteries in the TPMS sensors (if applicable).

4. TPMS Reset

Reset the system: Follow the manufacturer’s procedure for resetting the TPMS, which often involves pressing the TPMS reset button (if equipped) or navigating through the vehicle settings on the dashboard display.
Test drive the vehicle: Drive the vehicle for a short distance (about 10-15 minutes) to allow the system to recalibrate.
