Solution

1. Preparation

Gather tools: Multimeter, socket set, wire brush, OBD-II scanner, safety gloves.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative battery terminal using a socket wrench.
Sub-step 2: Clean the battery terminals and connectors using a wire brush to remove any corrosion.
Sub-step 3: Reconnect the battery terminal tightly and check for secure connections.

3. Test the Battery

Sub-step 1: Use the multimeter to measure the battery voltage; it should be above 12.4 volts.
Sub-step 2: If the voltage is low, attempt to jump-start the vehicle with jumper cables and another vehicle or a jump starter.

4. Starter Relay and Fuse Check

Sub-step 1: Locate the fuse box and identify the starter relay.
Sub-step 2: Swap the starter relay with another identical relay in the fuse box to test functionality.
Sub-step 3: Inspect and replace any blown fuses that are related to the starting system.

5. Starter Motor Inspection

Sub-step 1: If previous steps do not resolve the issue, access the starter motor (usually located near the transmission).
Sub-step 2: Check for loose connections and ensure that the wiring harness is intact.
Sub-step 3: Consider replacing the starter motor if it is faulty.
