Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, jumper cables
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Remove the negative (-) terminal, followed by the positive (+) terminal.
- Clean any corrosion using a battery terminal cleaner or a mixture of baking soda and water.
- Reconnect terminals securely.
Test and Replace Battery
- Use a multimeter to measure the battery voltage. If it is below 12.4 volts, consider charging or replacing the battery.
- If replacement is necessary, remove the old battery (unbolt and lift out) and install a new battery of the same specifications.

3. Starter Inspection

Check Starter Relay
- Locate the starter relay in the fuse box.
- Remove the relay and inspect it visually for any damage; replace if necessary.
- Swap with a similar relay to test if the starter operates with a different relay.
Inspect Starter Motor
- Remove the starter motor from its mounting (typically requires unbolting).
- Check for any signs of damage or wear.
- Test the starter motor by applying direct power from the battery; if it does not engage, replace the starter motor.
