Solution

1. Preparation

Gather tools and safety gear: gloves, safety glasses, multimeter, socket set.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Remove Battery Terminals
- Use a socket wrench to loosen the negative terminal (black) first, then the positive terminal (red).
- Clean any corrosion from the terminals and battery posts.
Test Battery Condition
- Use a multimeter to measure the battery voltage.
- If below 12.4 volts, proceed to charge or replace the battery.
Replace Battery (if necessary)
- Disconnect the old battery and remove it from the vehicle.
- Install the new battery by placing it in the battery tray and reconnecting the positive terminal first, followed by the negative terminal.
- Ensure terminals are tight and free of corrosion.

3. Starter Motor Testing and Replacement

Locate and Access Starter Motor
- Refer to the vehicle's service manual for the exact location; typically found near the transmission.
- Remove any components obstructing access (e.g., air intake duct).
Test Starter Motor
- Using jumper cables, connect the positive lead directly to the starter solenoid and the negative lead to the starter body.
- If the starter does not engage, it may need replacement.
Replace Starter Motor (if necessary)
- Disconnect the starter wiring harness and remove the mounting bolts using a socket set.
- Install the new starter motor in the reverse order, ensuring all connections are secure.
