Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, screwdriver, and safety gloves.
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Check Battery Health
- Reconnect the multimeter to the battery terminals.
- If voltage is below 12.4 volts, recharge or replace the battery.
Clean Terminals
- Remove battery terminals (first negative, then positive).
- Clean any corrosion with a wire brush and a mixture of baking soda and water, then dry completely.
- Reconnect terminals securely.

3. Starter and Ignition System Check

Inspect Starter Connections
- Locate the starter motor; usually found near the bottom of the engine, near the transmission.
- Ensure the wiring to the starter is secure and free of damage.
Test Starter Operation
- Using a jumper wire, connect the battery positive terminal directly to the starter terminal.
- If the starter engages and the engine cranks, the issue is likely with the ignition switch or solenoid.

4. Replace Components (if necessary)

Replace Battery
- If the battery is faulty, replace it with a new one of the same specifications.
Replace Starter or Ignition Switch
- If the starter or ignition switch is defective, replace with OEM or quality aftermarket parts, following manufacturer specifications for installation.
