Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, hammer, and flashlight.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the battery negative terminal to ensure safety.

2. Battery Inspection

Sub-step 1: Remove the battery terminal connections (negative first, then positive).
Sub-step 2: Clean any corrosion from the terminals using a wire brush and a solution of baking soda and water.
Sub-step 3: Reconnect the terminals securely and check for tightness.

3. Starter Motor Inspection

Sub-step 1: Locate the starter motor (usually near the transmission).
Sub-step 2: Disconnect the wiring harness from the starter motor.
Sub-step 3: Remove the starter motor bolts using a socket set and carefully take out the starter.
Sub-step 4: Test the starter by connecting it directly to a fully charged battery (ensure correct polarity).
Sub-step 5: If the starter does not engage, replace it with a new unit.

4. Electrical System Check

Sub-step 1: Inspect the ignition fuse and replace if blown (check the fuse box for the specific fuse location).
Sub-step 2: Test the starter relay by swapping it with a similar relay in the fuse box to see if the issue resolves.
Sub-step 3: Check and repair any damaged wiring to the starter.
