Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Clean Battery Connections

Remove the positive and negative battery terminals.
Clean the terminals and battery posts using a wire brush to remove corrosion.
Reconnect the terminals securely, starting with the positive terminal followed by the negative terminal.

3. Test and Replace Battery (if necessary)

If the battery voltage is low, attempt to jump-start the vehicle.
If the vehicle starts, charge or replace the battery.
For replacement, remove the battery from the tray and replace it with a new one, ensuring correct orientation and secure connections.

4. Check Starter Motor

Locate the starter motor (usually near the engine/transmission interface).
Disconnect the wiring harness from the starter.
Using jumper cables, connect the starter directly to the battery to test its operation.
If the starter does not engage, replace it.

5. Inspect Ignition Switch and Relay

Remove the steering column cover to access the ignition switch.
Use a multimeter to check for continuity when the key is turned to the start position.
If there is no continuity, replace the ignition switch.
Inspect and replace the starter relay if it shows signs of failure.
