Solution

1. Preparation

Gather necessary tools: multimeter, socket set, jumper cables, OBD-II scanner.
Ensure the vehicle is in a safe location and the parking brake is engaged.
Disconnect the negative battery terminal to avoid electrical shorts during inspection.

2. Battery Inspection and Replacement

Inspect Battery Condition
- Visually check the battery for signs of corrosion or damage.
- Clean any corrosion from battery terminals using a wire brush and a solution of baking soda and water.
Test Battery Voltage
- Reconnect the battery terminals and use a multimeter to measure voltage.
- If voltage is below 12.4 volts, proceed to replace the battery.
Replace Battery
- Remove the battery hold-down bracket and carefully lift the battery out of the tray.
- Install the new battery in reverse order, ensuring terminals are tightened securely.
- Reconnect the negative terminal last.

3. Starter Motor Inspection

Locate the Starter Motor
- Refer to the vehicle manual to find the starter motor's location.
Test Starter Motor
- Disconnect the starter motor electrical connector and use a multimeter to check for voltage at the terminal while attempting to start the vehicle.
- If no voltage is detected, check the ignition switch and wiring continuity.
Replace Starter Motor if Necessary
- Remove the starter motor from its mounting using a socket set.
- Install the new starter motor and reconnect all wiring.
