Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Check Battery Voltage
- Reconnect the multimeter to the battery terminals.
- If the voltage is below 12.4 volts, proceed to charge or replace the battery.
Clean Battery Terminals
- Use a wire brush to clean corroded terminals.
- Reconnect terminals securely.
Replace Battery (if needed)
- Remove the battery hold-down bracket using a socket set.
- Carefully lift the battery out of the tray.
- Install the new battery in reverse order, ensuring correct polarity.

3. Starter Inspection and Replacement

Locate the Starter
- The starter is typically located on the engine block near the transmission.
- Remove any covers or shields obstructing access.
Test Starter Motor
- Use a multimeter to check for voltage at the starter solenoid when the ignition is turned on.
- If there is no voltage, trace back to the ignition switch and wiring.
Replace Starter (if necessary)
