Solution

1. Preparation

Gather tools: Multimeter, socket set, wire brush, jumper cables, and safety goggles.
Ensure the vehicle is in park (for automatic) or neutral (for manual) with the parking brake engaged.

2. Battery Inspection and Cleaning

Sub-steps:
1. Disconnect the negative (-) battery terminal first, followed by the positive (+) terminal.
2. Clean the battery terminals and cable connectors with a wire brush to remove any corrosion.
3. Reconnect the positive (+) terminal first, then the negative (-) terminal.

3. Starter Relay Testing

Sub-steps:
1. Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
2. Remove the relay and visually inspect it for damage.
3. Swap the starter relay with another identical relay in the fuse box.
4. Attempt to start the vehicle again.

4. Starter Motor Bypass Test

Sub-steps:
1. Locate the starter motor, usually situated near the transmission.
2. Use jumper cables to connect the positive terminal of the battery to the starter motor's positive terminal.
3. Ground the starter by connecting the negative cable to the starter housing.
4. If the starter engages and the engine cranks, the starter motor is functioning.

5. Ground Connection Check

Sub-steps:
1. Inspect the ground strap connecting the battery to the chassis and engine.
2. Clean contact points and ensure they are tightly secured.
3. Replace any damaged ground cables.
