Solution

1. Preparation

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

2. Diagnose and Address Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Record any error codes that appear on the scanner.
Clear the error codes and observe if any reappear after a short test drive.

3. Address Engine Warning Light

Identify the specific issue from the error codes (e.g., faulty sensors, misfires).
Replace or repair the faulty components as indicated by the codes.
Reconnect the battery and test the vehicle to see if the warning light is resolved.

4. Inspect and Repair ABS and Traction Control Lights

Check the ABS sensors located at each wheel for damage or disconnection.
Inspect the wiring harness for any frays or corrosion.
If necessary, replace the faulty ABS sensor or repair the wiring.

5. Battery and Charging System Check

Test the battery voltage using a multimeter (should be around 12.6 volts for a healthy battery).
Inspect the alternator belt for wear or looseness and replace if needed.
If the alternator is faulty, replace it to ensure proper charging of the battery.

6. Brake System Inspection

Inspect the brake fluid reservoir and refill if low, using DOT 3 or DOT 4 brake fluid as specified.
Test the brake pedal for firmness; if spongy, bleed the brakes to remove air.
Replace any faulty brake components as necessary.
