Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to prevent any electrical issues during inspection.
Ensure the engine is cool before working on it.

2. Scan and Interpret Codes

Use the OBD-II scanner to retrieve error codes.
Document the codes and refer to the repair manual for specifics on each code.

3. Address Ignition System

Tools Required: Socket set, torque wrench, spark plug socket.
Remove the ignition coils and inspect for damage or wear.
