Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect the Battery
- Clean any corrosion from the battery terminals using a wire brush.
- Tighten the battery cable connections securely.
Test/Replace Battery
- If the battery voltage is low or it fails the load test, replace it with a new battery of the same specifications (Group Size, CCA rating).
- Reconnect the battery terminals, starting with the positive terminal.

3. Starter Relay and Fuse Check

Locate the Starter Relay
- Refer to the vehicle’s owner manual for the location of the starter relay.
Test the Relay
- Swap the starter relay with another identical relay in the fuse box to check functionality.
- If the vehicle starts with a swapped relay, replace the faulty relay.
Inspect Fuses
- Check the starter fuse for continuity; replace it if blown.

4. Starter Motor Inspection and Replacement

Access the Starter Motor
- Remove any components obstructing access to the starter motor (e.g., air intake duct).
Check Connections
- Verify that the wiring to the starter motor is secure and free from damage.
Test the Starter
- If the connections are good, perform a bench test on the starter motor or replace it if necessary.
Reinstall Components
- Reinstall any components that were removed and secure them properly.
