Solution

1. Preparation

Gather tools: Multimeter, socket set, jumper cables, wrench set, and safety gloves.
Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Disconnect the negative cable first, then the positive cable.
- Clean any corrosion using a wire brush and a mixture of baking soda and water.
- Reconnect the positive cable first, followed by the negative cable.
Test Battery Voltage
- Use a multimeter to measure the battery voltage.
- If under 12.4 volts, charge the battery or replace if it cannot hold a charge.
Replace Battery (if necessary)
- Remove the battery securing bracket using the socket set.
- Lift out the old battery carefully.
- Install the new battery in reverse order, securing it firmly.

3. Starter Motor Check

Bypass Starter Motor
- Locate the starter motor and identify the terminals.
- Use jumper cables to connect the battery positive directly to the starter terminal.
- If the starter engages and the engine cranks, the starter is likely faulty.
Remove and Replace Starter Motor (if faulty)
- Disconnect the battery again (negative terminal first).
- Remove any mounting bolts and electrical connections from the starter.
- Install the new starter motor, ensuring all connections are secure.
