Solution

1. Preparation

Gather tools: Multimeter, jumper cables, socket set, torque wrench.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative terminal of the battery for safety.

2. Battery Inspection

Sub-step 1: Remove the battery terminals (negative first, then positive).
Sub-step 2: Clean any corrosion from the terminals and battery posts using a wire brush.
Sub-step 3: Reconnect the terminals securely (positive first, then negative).

3. Battery Replacement (if necessary)

Sub-step 1: If the battery voltage is below 12.6 volts after testing, replace the battery.
Sub-step 2: Remove the old battery from the tray after loosening the hold-down clamp.
Sub-step 3: Install the new battery and secure it in place.

4. Starter Motor Testing

Sub-step 1: Reconnect the battery terminals.
Sub-step 2: Locate the starter motor and check its connections.
Sub-step 3: Use a jumper wire to connect directly to the starter to test if it engages; if it does not, the starter may need replacement.

5. Check Ignition Switch and Relay

Sub-step 1: Inspect the ignition switch for wear or damage; replace if faulty.
Sub-step 2: Locate the starter relay in the fuse box; replace with a known working relay.
