Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location and securely parked.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-step 1: Use a multimeter to measure the battery voltage. It should read at least 12.6 volts for a fully charged battery.
Sub-step 2: If the voltage is below 12.4 volts, recharge or replace the battery.
Sub-step 3: Clean the battery terminals and connections with a wire brush to remove corrosion.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor (usually near the transmission).
Sub-step 2: Using a jumper wire, connect the positive terminal of the battery directly to the starter motor terminal.
Sub-step 3: If the starter engages and the engine turns over, the starter is functional; if not, consider replacing the starter.

4. Ignition Switch Check

Sub-step 1: Disconnect the ignition switch connector.
Sub-step 2: Test the switch for continuity using a multimeter when turning the key to the start position.
Sub-step 3: Replace the ignition switch if there is no continuity.
