Solution

1. Preparation

Gather necessary tools such as an OBD-II scanner, tire pressure gauge, and TPMS reset tool if applicable.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection and Adjustment

Sub-step 1: Use a tire pressure gauge to measure the pressure in each tire.
Sub-step 2: Inflate or deflate the tires to the manufacturer-recommended pressure as indicated on the driver's side door jamb.
Sub-step 3: Inspect the sidewalls and treads of each tire for any visible damage.

3. TPMS Sensor Inspection

Sub-step 1: Remove the wheel covers or hubcaps as necessary to access the TPMS sensors.
Sub-step 2: Inspect each TPMS sensor for physical damage, corrosion, or loose connections.
Sub-step 3: If sensors are damaged, replace them with new TPMS sensors compatible with the Toyota Camry XV40.

4. Resetting the TPMS

Sub-step 1: Follow the manufacturer’s procedure to reset the TPMS system, typically involving turning the ignition on and off while pressing the reset button (located near the steering column or under the dashboard).
Sub-step 2: Drive the vehicle for at least 10 minutes at speeds of 30 mph or above to allow the system to recalibrate.
