Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner, and jumper cables.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from the battery terminals using a terminal cleaner or a wire brush.
- Ensure connections are tight and secure.
Check Battery Voltage
- Connect the multimeter to the battery terminals (red to positive, black to negative).
- If the voltage is below 12.4 volts, proceed to charge or replace the battery.
Load Test the Battery
- Use a battery load tester to simulate a load on the battery.
- If the battery fails the load test, replace it with a new battery of the same specifications.

3. Starter Motor Inspection

Check Starter Relay
- Locate the starter relay in the fuse box and remove it.
- Swap it with a similar relay to test functionality. If the vehicle starts, replace the faulty relay.
Inspect Starter Connections
- Reconnect the negative battery terminal.
- Locate the starter motor and check the wiring for any damage or loose connections.
- Tighten connections as necessary.
Test Starter Functionality
- If the vehicle still does not start, perform a bench test on the starter motor. Remove the starter and connect it directly to a charged battery. If it does not spin, replace the starter.
