2
Inspect battery terminals and cables for corrosion or loose connections.
3

Solution

1. Preparation

Gather tools: Multimeter, socket set, battery terminal cleaner, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Disconnect the negative terminal of the battery using a wrench.
Clean any corrosion from the battery terminals and cable ends using a battery terminal cleaner.
Reconnect the terminals securely and ensure tight connections.

3. Battery Testing

Use a multimeter to measure the battery voltage. If below 12.4 volts, jump-start the vehicle using jumper cables.
- Sub-steps:
  - Connect positive (+) jumper cable to the dead battery's positive terminal.
  - Connect the other end of the positive jumper cable to the working battery’s positive terminal.
  - Connect the negative (-) jumper cable to the working battery's negative terminal.
  - Connect the other end of the negative jumper cable to a grounded metal surface on the dead vehicle.
Attempt to start the vehicle.

4. Starter Motor Check

If the vehicle still does not start, locate the starter motor.
Using the socket set, disconnect the starter motor wiring.
Apply direct battery voltage to the starter motor terminals.
If the starter engages and cranks the engine, replace the starter motor.
If it does not crank, further diagnosis of the ignition switch or wiring may be necessary.

5. Replacement (if required)

If the battery or starter motor needs replacement:
- Remove the old part by reversing the installation process.
- Install the new battery or starter motor.
- Ensure all connections are tight and secure.
