Solution

1. Preparation

Gather tools: Multimeter, socket set, screwdriver, jumper cables, OBD-II scanner.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Reconnect the battery terminal if it was disconnected.
Use a multimeter to measure the battery voltage. If it’s below 12.4 volts, proceed to jump-start the vehicle or replace the battery if it's old and weak.
Clean the battery terminals with a wire brush if corrosion is present. Ensure the connections are tight.

3. Starter Motor Test

Locate the starter motor (usually found near the engine transmission).
Disconnect the wiring harness from the starter.
Use jumper cables to provide power directly to the starter motor. If the motor engages, it may need replacement.
If the starter does not engage, further inspect the wiring and connections.

4. Fuse and Wiring Inspection

Open the fuse box and check fuses related to the starting system and dashboard lights.
Replace any blown fuses with the same amp rating.
Inspect the ignition switch wiring for fraying or disconnection.
