Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, OBD-II scanner.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Inspect and Charge Battery

Sub-step 1: Test the battery voltage with the multimeter. If the voltage is below 12.4 volts, charge the battery using a battery charger.
Sub-step 2: If the battery is old (over 3-5 years), consider replacing it.

3. Clean and Tighten Battery Connections

Sub-step 1: Disconnect the negative terminal first, followed by the positive terminal.
Sub-step 2: Clean any corrosion from the terminals and cable connections using a wire brush or terminal cleaner.
Sub-step 3: Reconnect the positive terminal first, then the negative terminal, ensuring they are tight.

4. Test and Replace Starter Motor (if necessary)

Sub-step 1: Use a jumper wire to bypass the starter solenoid to see if the starter engages.
Sub-step 2: If the starter does not engage, remove the starter motor from the vehicle.
Sub-step 3: Test the starter with a bench test or replace it if it shows signs of failure.

5. Check Fuses and Relays

Sub-step 1: Locate the fuse box and check the relevant fuses for the starter and ignition system.
Sub-step 2: Replace any blown fuses with the same amperage rating.
Sub-step 3: Test the starter relay by swapping it with a similar relay in the fuse box to see if it resolves the issue.
