Solution

1. Preparation

Gather tools: multimeter, socket set, wrenches, battery terminal cleaner, and a new battery if necessary.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect Battery
- Use a wrench to disconnect the negative (-) terminal first, followed by the positive (+) terminal.
- Safety Warning: Disconnecting the battery can reset electronic systems; be sure to have the radio code if applicable.
Clean Terminals
- Use a battery terminal cleaner to remove any corrosion from the battery terminals and cable ends.
Test Battery
- Connect the multimeter to measure the voltage of the battery.
- If the voltage is below 12.4 volts, proceed to replace the battery.
Replace Battery (if necessary)
- Remove the old battery from the tray by unscrewing any hold-downs.
- Place the new battery in the tray and secure it using the hold-downs.
- Reconnect the positive (+) terminal first, followed by the negative (-) terminal.

3. Starter Motor and Relay Inspection

Check Starter Relay
- Locate the starter relay in the fuse box and swap it with a similar relay to test functionality.
- If the starter engages with the swapped relay, replace the faulty relay.
Inspect Starter Motor
- If the relay is functioning, check the starter motor connections.
- Remove the starter motor if necessary to inspect for any physical damage or wiring issues.
Test Starter Motor
- Connect the starter directly to the battery to see if it engages.
- If the starter does not engage, replace the starter motor.
