Solution

1. Preparation

Tools Required: Multimeter, Socket set, Wrench set, OBD-II scanner, Safety gloves
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean any corrosion from the terminals and cable ends using a wire brush.
3. Reconnect the battery terminals securely (positive first, then negative).
4. Test the battery voltage again; if below 12.4 volts, proceed to replacement.

3. Starter Relay Check

Sub-steps:
1. Locate the fuse box under the hood and identify the starter relay.
2. Remove the starter relay and inspect for any visible damage.
3. Swap the relay with an identical one (such as the horn relay) to test functionality.
4. Reinstall the relay and attempt to start the vehicle.

4. Starter Motor Replacement (if necessary)

Sub-steps:
1. Locate the starter motor, typically near the bottom of the engine near the transmission.
2. Disconnect the battery again if not already done.
3. Remove the electrical connections from the starter motor (usually a main power cable and a smaller signal wire).
4. Unbolt the starter motor using a socket set, paying attention to any mounting bracket.
5. Install the new starter motor and reconnect all electrical connections.
6. Secure the starter motor with the bolts and reconnect the battery.
