Solution

1. Preparation

Gather tools including a multimeter, OBD-II scanner, socket set, and wrenches.
Ensure safety gear is worn (gloves and safety glasses).
Disconnect the negative battery terminal to prevent accidental shorts.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Remove any corrosion using a wire brush.
- Tighten loose connections securely.
Test and Replace Battery (if needed)
- Use a multimeter to check the voltage; if below 12.4 volts, recharge or replace the battery.
- If replacing, ensure the new battery matches the specifications (size, capacity).
- Install the new battery, connecting the positive terminal first, followed by the negative.

3. Starter Inspection and Replacement

Locate the Starter
- Refer to the vehicle service manual for the exact location.
Remove Starter
- Disconnect the electrical connectors carefully.
- Unbolt the starter from its mounting (typically 2-3 bolts).
- Remove the starter from the engine bay.
Install New Starter
- Position the new starter in place and secure it with bolts to the specified torque (usually around 20-25 ft-lbs, check service manual).
- Reconnect electrical connectors ensuring a tight fit.

4. Final Checks

Reconnect the negative battery terminal.
Start the vehicle to check if the issue is resolved.
