Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery before starting work on electrical components.

2. Battery and Charging System Inspection

Use a multimeter to check the battery voltage; it should read between 12.4V to 12.7V when the engine is off.
If voltage is low, check battery connections for corrosion or looseness.
Start the engine and measure voltage again; it should read between 13.7V to 14.7V, indicating proper charging.
If the voltage is out of range, test the alternator and replace if faulty.

3. Brake System Check

Inspect the brake fluid reservoir; if low, top it off with the recommended brake fluid (DOT 3 or DOT 4).
Look for any signs of leaks in brake lines or around calipers.
If leaks are found, replace damaged components and bleed the brake system.

4. ABS System Inspection

Check the ABS module for any loose connections or damaged wiring.
Use the OBD-II scanner to identify specific ABS fault codes; clear codes if repairs have been made.
If ABS module is faulty, replace it according to manufacturer's specifications.

5. Engine Performance Verification

Inspect spark plugs and ignition coils for wear or damage; replace as needed.
Check for vacuum leaks or issues with the intake system.
Ensure the coolant level is adequate and check for any signs of overheating.
