Solution

1. Preparation

Tools Needed: Multimeter, socket set, screwdriver, jumper wire, wire brush
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Cleaning

Remove the battery terminals (negative first, then positive).
Use a wire brush to clean any corrosion from the battery terminals and connectors.
Ensure the battery terminals are tight and properly seated before reconnecting.

3. Testing and Replacing the Battery

Reconnect the battery and perform a voltage test; if below 12.4 volts, consider replacing the battery.
If the battery is faulty, remove it using a socket set and replace it with a new one, ensuring the positive terminal is connected first, followed by the negative.

4. Starter Motor Inspection

Locate the starter motor (usually near the transmission).
Check the connections to the starter motor for tightness and corrosion.
If necessary, remove the starter motor for testing; refer to the vehicle manual for specific removal instructions.
Test the starter motor using a bench test or replace it if it’s defective.

5. Ignition Switch and Relay Check

Locate the ignition switch; check the connections and wiring for any signs of wear.
Test the starter relay by swapping it with another relay of the same type in the fuse box.
Replace the ignition switch or starter relay if they show signs of failure.
