Test the voltage of the battery using a multimeter; it should read around 12.6 volts when fully charged.
3
Check the fuses related to the starter and ignition system.
4
Verify the operation of the starter motor by bypassing it with a direct connection.
5
Scan for any error codes using an OBD-II scanner to check for potential faults in the engine management system.
6
Inspect the ignition switch for functionality.

Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, wrench set, screwdriver set
Disconnect the battery to ensure safety while working on the electrical system.

2. Battery Terminal Cleaning

Remove the negative (-) terminal first, followed by the positive (+) terminal.
Clean the terminals and cable ends with a wire brush; remove all corrosion.
Reconnect the positive (+) terminal first, then the negative (-) terminal.

3. Battery Replacement (if necessary)

If the battery voltage is below 12.4 volts, consider replacing the battery.
Tools Required: Wrench set
Remove the battery hold-down clamp and lift the battery out of the tray.
Install the new battery in the reverse order and ensure terminals are tightened.

4. Starter Motor Inspection

Locate the starter motor (typically near the engine block).
Check wiring connections for tightness and any signs of wear or damage.
Use jumper cables to connect the starter directly to the battery. If it does not engage, the starter may need replacement.

5. Ignition Switch Testing

Remove the steering column cover to access the ignition switch.
Use a multimeter to check for continuity in the ignition switch when turned to the start position. Replace if defective.
