Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and wrenches.
Ensure the vehicle is in park and the ignition is off. Disconnect the negative battery terminal to prevent electrical short circuits.

2. Battery Inspection and Replacement

Inspect Battery:
- Check battery terminals for corrosion; clean with a wire brush if necessary.
- Tighten any loose connections.
Replace Battery (if needed):
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and install the new one in reverse order.
- Ensure connections are tight and secure.

3. Starter Relay and Fuse Check

Check Starter Relay:
- Locate the starter relay in the fuse box.
- Swap the starter relay with a known working relay to test functionality.
Inspect Fuses:
- Locate the fuse box and check for any blown fuses related to the starting system.
- Replace any blown fuses with the correct amperage.

4. Starter Motor Inspection and Replacement

Inspect Starter Motor:
- Locate the starter motor; typically found near the engine block.
- Check for loose connections or damaged wires.
Replace Starter Motor (if necessary):
- Disconnect battery if not already done.
- Remove the electrical connector from the starter.
- Unbolt the starter motor from the engine using a socket set.
- Install the new starter motor and reverse the disassembly steps.
- Reconnect the electrical connector and tighten securely.
