Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, cleaning supplies.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the negative terminal of the 12V battery to ensure safety.

2. Address Software Issues

Connect the OBD-II scanner and clear any error codes.
Check for software updates by accessing the vehicle's settings. Follow prompts to update if necessary.

3. Inspect and Replace the 12V Battery (if required)

Use the multimeter to check the voltage of the 12V battery (should be around 12.6V when fully charged).
If the battery is underperforming, remove it by:
1. Disconnecting the negative terminal first, then the positive terminal.
2. Removing the battery hold-down bracket.
3. Carefully lifting the battery out.
Install a new 12V battery, ensuring correct polarity, and reconnect the terminals (positive first, then negative).

4. Clean the Throttle Body

Remove the throttle body by:
1. Disconnecting the intake duct connected to the throttle body.
2. Removing the throttle body mounting bolts (torque to spec upon reinstallation).
3. Using throttle body cleaner, spray and clean the inside, ensuring no residue remains.
Reinstall the throttle body and reconnect all hoses and electrical connectors.

5. Check Fuel Delivery System

Inspect the fuel pump by:
1. Accessing the fuel pump relay and verifying operation.
2. If necessary, replace the fuel filter according to manufacturer specifications.
Ensure fuel lines are not kinked or blocked.
