Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, battery terminal cleaner, and safety goggles.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection and Replacement

Check Battery Health
- Remove the battery cables, starting with the negative (-) terminal.
- Clean the terminals using a battery terminal cleaner.
- Reconnect and check voltage again; if below 12.4V, proceed to replacement.
Replace Battery (if necessary)
- Use a socket set to remove the battery hold-down clamp.
- Lift out the old battery and place the new battery in the tray.
- Reattach the hold-down clamp and connect the positive (+) terminal first, followed by the negative (-) terminal.

3. Starter and Relay Testing

Starter Relay
- Locate the starter relay in the fuse box.
- Remove the relay and swap it with a similar relay to test if the starter engages.
Starter Replacement (if necessary)
- Disconnect the battery.
- Remove the starter by unscrewing the bolts with a socket set.
- Disconnect the wiring harness from the starter.
- Install the new starter by reversing the removal steps and ensuring all connections are tight.
