- Wrench set
- Screwdriver set
- Safety gloves
Ensure the vehicle is in park or neutral with the parking brake engaged. Disconnect the negative battery terminal.

2. Inspect Battery Connections

Sub-steps:
1. Remove the battery terminal covers if present.
2. Using a wrench, loosen and remove the negative battery terminal.
3. Clean any corrosion from the terminal and battery post using a wire brush.
4. Tighten the terminal securely and reconnect the negative terminal.

3. Test and Replace the Battery (if necessary)

Sub-steps:
1. Reconnect the battery and use a multimeter to check voltage. If it's below 12.4 volts, proceed with replacement.
2. Remove the battery using a wrench for the hold-down bracket.
3. Install a new battery (ensure it is the correct type and rating as specified in the owner’s manual).
4. Reconnect the terminals, first positive then negative.

4. Check Starter and Solenoid

Sub-steps:
1. Locate the starter motor beneath the vehicle.
2. Disconnect the wiring harness from the starter solenoid.
3. Check for continuity across the solenoid terminals with a multimeter.
4. If faulty, remove the starter by unscrewing the mounting bolts and replace it with a new unit.
5. Reconnect all wiring securely.

5. Final Assembly and Testing

Sub-steps:
1. Reconnect the negative battery terminal securely.
