Solution

1. Preparation

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

2. Battery Inspection

Disconnect Battery: Use a socket set to disconnect the negative terminal first, followed by the positive terminal.
Clean Terminals: Use battery terminal cleaner to remove any corrosion from the terminals.
Check Voltage: Use a multimeter to measure the battery voltage. A fully charged battery should read around 12.6 volts.
Charge Battery: If the voltage is below 12.4 volts, charge the battery using a battery charger.

3. Starter and Ignition System Check

Reconnect Battery: Reconnect the positive terminal first, then the negative terminal.
Test Starter Motor: Use jumper cables to connect the starter motor directly to the battery (caution: ensure the vehicle is in a safe environment).
Inspect Connections: Check all wiring and connections to the starter motor for wear or damage.
Replace Starter Relay: If the starter does not engage, check and replace the starter relay if it appears faulty.

4. Final Assembly

Reconnect Battery: Ensure all connections are secure and reconnect the battery terminals.
Test Start: Attempt to start the vehicle and listen for any abnormal sounds.
