Solution

1. Preparation

Gather tools and materials: battery terminal cleaner, multimeter, wrench set, OBD-II scanner, and replacement parts if needed.
Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative battery terminal using a wrench.
Sub-step 2: Clean any corrosion from the battery terminals and connectors using a battery terminal cleaner.
Sub-step 3: Reconnect the negative battery terminal securely.

3. Battery Testing

Sub-step 1: Use a multimeter to measure the battery voltage. If it is below 12.4 volts, charge or replace the battery.
Sub-step 2: If the battery is good, proceed to check connections to the starter.

4. Starter Circuit Inspection

Sub-step 1: Inspect the wiring from the battery to the starter. Look for fraying, corrosion, or loose connections.
Sub-step 2: If damaged wiring is found, repair or replace as necessary.

5. Starter and Relay Testing

Sub-step 1: Locate the starter relay in the fuse box and remove it.
Sub-step 2: Use a multimeter to check for continuity in the relay. Replace if faulty.
Sub-step 3: Test the starter motor by bypassing the relay with a jumper wire; if the starter engages, replace the relay.

6. Final Assembly

Sub-step 1: Reinstall any components removed during inspection.
Sub-step 2: Reconnect the battery and ensure all connections are tight.
