Solution

1. Preparation

Gather tools: multimeter, socket set, wrench, screwdriver, and cleaning brush.
Ensure the vehicle is in "Park" with the parking brake engaged.
Disconnect the negative terminal of the battery for safety.

2. Battery Inspection and Replacement

Inspect battery terminals:
- Remove the positive terminal first, followed by the negative terminal.
- Clean terminals using a wire brush; reconnect tight and secure.
Test battery condition:
- If the voltage is below 12.4 volts, charge the battery or replace it.
- Replace with a high-quality battery that meets OEM specifications.

3. Starter Inspection and Replacement

Remove starter:
- Locate the starter motor, typically near the transmission.
- Disconnect the wiring harness and remove the mounting bolts using a socket set.
Test starter motor:
- Use a multimeter to check for continuity; if faulty, replace the starter.
Install new starter:
- Position the new starter in place and secure it with the mounting bolts.
- Reconnect the wiring harness.

4. Final Assembly

Reconnect the battery terminals, ensuring the positive terminal is connected first.
Inspect all connections and ensure they are tight and corrosion-free.
