Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a hammer.
Ensure the vehicle is in park (or neutral) and the parking brake is engaged.
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Inspection

Check Connections:
1. Inspect the battery terminals for corrosion and clean them with a wire brush if necessary.
2. Ensure the terminals are tight and secure.
Test Battery:
1. Reconnect the negative terminal and use a multimeter to measure the voltage.
2. If the voltage is below 12.4 volts, consider jump-starting the vehicle or replacing the battery.

3. Starter Assessment

Starter Tap Test:
1. Locate the starter motor, typically found near the transmission bell housing.
2. Carefully tap the starter with a hammer while someone else attempts to start the engine.
3. If the engine starts, the starter may need replacement.
Starter Circuit Check:
1. Inspect the wiring harness connected to the starter for damage.
2. Use the multimeter to check for voltage at the starter when the key is turned to the start position.

4. Replace Components

If the battery is faulty, replace it with a new one of the same specifications.
If the starter is faulty, remove the old starter:
1. Disconnect the electrical connections.
2. Remove mounting bolts using a socket set.
3. Install the new starter by reversing the removal steps, ensuring all connections are secure.
