Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery cable to prevent electrical shock.

2. Battery Inspection

Step 1: Clean battery terminals with a wire brush to remove any corrosion.
Step 2: Securely tighten the battery terminal connections.
Step 3: If the battery voltage is low, jump-start the vehicle or replace the battery if necessary.

3. Starter Relay Replacement

Step 1: Locate the starter relay in the fuse box (refer to the owner's manual for specific location).
Step 2: Remove the starter relay and replace it with a new one.
Tools Required: Relay puller or flathead screwdriver.

4. Starter Motor Inspection

Step 1: Locate the starter motor (usually found near the engine block).
Step 2: Inspect electrical connections at the starter motor for tightness and corrosion.
Step 3: If connections are secure but issues persist, remove the starter motor for bench testing or replacement.
