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 ensure safety during inspection and repairs.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Record any error codes and refer to the vehicle service manual for definitions.

3. Address Specific Issues

Based on error codes retrieved, follow the manufacturer's service manual for specific repairs (e.g., replace faulty sensors, clear error codes).
If low fluid levels were detected, refill the necessary fluids according to specifications.

4. Inspect and Repair Components

If physical damage is found (e.g., cracked hoses, worn belts), remove and replace those components.
Tighten any loose connections that may cause intermittent issues.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any error codes once repairs are complete.
