1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts during repair.

2. Address Diagnostic Codes

Sub-step 1: Connect the OBD-II scanner and retrieve stored error codes.
Sub-step 2: Document the codes and refer to the service manual for their meanings.
Sub-step 3: Clear the codes and restart the vehicle to see if the warning lights return.

3. Check and Replace Fluids

Sub-step 1: Open the hood and check the oil level using the dipstick; add oil if low.
Sub-step 2: Check coolant levels in the reservoir; refill with the appropriate type if necessary.
Sub-step 3: Inspect brake fluid levels and top up with the recommended fluid type.

4. Inspect Battery and Charging System

Sub-step 1: Use a multimeter to check the battery voltage (should be around 12.6 volts when fully charged).
Sub-step 2: Examine battery terminals for corrosion; clean if necessary.
Sub-step 3: Check connections to the alternator for tightness and signs of wear.

5. Examine ABS and Traction Control Sensors

Sub-step 1: Locate and visually inspect the wheel speed sensors for damage or disconnection.
Sub-step 2: Test the sensors with a multimeter for proper resistance according to specifications.
Sub-step 3: Replace any faulty sensors as indicated by testing results.

6. Check Fuses

Sub-step 1: Locate the fuse box and identify fuses related to dashboard warnings.
Sub-step 2: Inspect each fuse for continuity and replace any that are blown.
Sub-step 3: Reinstall the fuse box cover securely after inspection.
