Solution

1. Preparation

Gather tools: wrenches, multimeter, battery load tester, OBD-II scanner.
Ensure the vehicle is in a safe location and on level ground.
Disconnect the battery to prevent any electrical shorts.

2. Clean Battery Terminals

Tools Required: Wire brush or terminal cleaner.
Remove the negative (-) cable first, followed by the positive (+) cable.
Clean the terminals and cable ends thoroughly until shiny.
Reconnect the positive (+) cable first, then the negative (-) cable.

3. Test and Replace Battery (if necessary)

Tools Required: Multimeter, battery load tester.
Reconnect the battery and measure voltage again; if below 12.6 volts, proceed.
Use a battery load tester to check if the battery can hold a load; if it fails, replace the battery with a new one.
Ensure the new battery is properly charged before installation.

4. Inspect and Test Starter Motor

Tools Required: Wrench set, multimeter.
Locate the starter motor and check the connections; tighten any loose connections.
Test for voltage at the starter motor while someone turns the key to the "start" position.
If no voltage is present, check ignition switch and wiring leading to the starter.
If voltage is present but the starter does not engage, replace the starter motor.
