Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical shorts while working on the vehicle.

2. Addressing Error Codes

Sub-step 2.1: Connect the OBD-II scanner to the vehicle's diagnostic port.
Sub-step 2.2: Record all error codes and research their meanings.
Sub-step 2.3: Clear the codes and perform a test drive to see if warning lights return.
Sub-step 2.4: If the lights return, focus on the specific codes to diagnose further.

3. Checking Battery and Electrical Connections

Sub-step 3.1: Inspect battery terminals for corrosion and clean them if necessary.
Sub-step 3.2: Use a multimeter to check battery voltage; it should read between 12.4 to 12.7 volts.
Sub-step 3.3: Replace the battery if voltage is low or it shows signs of failure.

4. Inspecting Tire Pressure and TPMS

Sub-step 4.1: Use a tire pressure gauge to check the pressure of all tires, including the spare.
Sub-step 4.2: Inflate tires to the recommended PSI as listed on the driver’s door jamb.
Sub-step 4.3: Reset the TPMS by following the vehicle’s manual procedure or using the TPMS reset button.

5. ABS and Brake System Inspection

Sub-step 5.1: Check the brake fluid level in the reservoir; add fluid if low.
Sub-step 5.2: Inspect brake lines for leaks or damage.
Sub-step 5.3: If ABS codes are present, test the wheel speed sensors and replace any faulty sensors.
