1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, battery terminal cleaner, new battery (if necessary), new starter relay (if necessary).
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Clean Battery Terminals:
- Disconnect the negative cable first, followed by the positive cable.
- Clean corrosion using a battery terminal cleaner or a mixture of baking soda and water.
Check Battery Voltage:
- Reconnect the battery terminals and use a multimeter to measure the voltage.
- If below 12.6 volts, proceed to replace the battery.
Replace Battery:
- Remove the old battery by unscrewing any retaining bracket.
- Install the new battery, connecting the positive terminal first, followed by the negative.

3. Starter Relay and Motor Inspection

Replace Starter Relay:
- Locate the starter relay under the hood in the fuse box.
- Remove the relay and install a new one, ensuring it is seated properly.
Inspect Starter Motor:
- If the vehicle still does not start, locate the starter motor.
- Check for loose or damaged wiring connected to the starter motor.
- If faulty, remove the starter motor by disconnecting electrical connections and unscrewing it from the engine.
