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 before performing electrical work.

2. Addressing Check Engine Light

Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostic port.
2. Read and record any trouble codes.
3. Research the codes to identify the specific issue (e.g., misfire, sensor failure).
4. Repair or replace faulty components as indicated by the trouble codes (e.g., replace spark plugs, oxygen sensors).

3. Battery and Electrical System Check

Sub-steps:
1. Remove the battery terminals and clean any corrosion.
2. Test the battery using a multimeter; replace if voltage is below 12.4V.
3. Inspect the alternator output; it should be between 13.7V to 14.7V while the engine is running.

4. ABS and Brake System Inspection

Sub-steps:
1. Check the brake fluid reservoir for proper fluid level; refill as needed using DOT 3 or DOT 4 fluid.
2. Inspect brake lines and connections for leaks or damage.
3. If ABS light remains on after addressing fluid issues, perform a diagnostic on the ABS module.
