Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery negative terminal to ensure safety.

2. Battery Inspection

1.1 Check battery condition: If the voltage is below 12.4 volts, charge or replace the battery.
1.2 Clean battery terminals: Remove corrosion using a wire brush and a mixture of baking soda and water. Ensure terminals are tight after cleaning.

3. Starter Relay Check

3.1 Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
3.2 Remove the starter relay and inspect for any signs of damage.
3.3 Swap with a similar relay to test if the issue resolves.

4. Starter Replacement (if necessary)

4.1 If the starter is suspected to be faulty, disconnect the battery negative terminal again.
4.2 Remove the starter motor:
- Disconnect wiring harness from the starter.
- Remove mounting bolts using a socket set.
- Carefully pull the starter out of the engine bay.
4.3 Install the new starter:
- Position the new starter in place.
- Secure with mounting bolts and torque them to specification (typically around 15-20 ft-lbs, but confirm with repair manual).
- Reconnect the wiring harness to the starter.

5. Reconnect Battery

Reattach the battery negative terminal and ensure it is secure.
