Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, socket set, and a screwdriver.
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged.
Disconnect the 12V battery before starting work on electrical systems.

2. Battery Inspection

Sub-steps:
1. Remove the battery cover (if applicable).
2. Disconnect the negative terminal first, followed by the positive terminal.
3. Clean any corrosion from the terminals using a wire brush and a solution of baking soda and water.
4. Reconnect the positive terminal first, then the negative terminal.
5. Test the battery voltage again with the multimeter. If it’s below 12.4V, consider replacing the battery.

3. Key Fob Check

Sub-steps:
1. Remove the battery cover from the key fob.
2. Replace the key fob battery with a new CR2032 battery.
3. Test the key fob by pressing the unlock button to see if the vehicle responds.

4. Starter Motor and Relay Inspection

Sub-steps:
1. Locate the starter motor (usually near the engine block).
2. Inspect wiring for damage or loose connections.
3. Test the starter relay by swapping it with another relay of the same type (check vehicle manual).
4. If you have access, perform a bench test of the starter motor by applying direct battery voltage to see if it engages.
