Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and jumper cables.
Ensure the vehicle is in "Park" (automatic) or "Neutral" (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect Battery:
- Use a socket set to remove the negative terminal first, followed by the positive terminal. This prevents electrical shorts.
Clean Terminals:
- Inspect battery terminals for corrosion. Clean with a wire brush if necessary and reconnect securely.
Test Battery:
- Use a multimeter to check the battery voltage. If below 12.4 volts, charge the battery or replace it if it's old.
Reconnect Battery:
- Reconnect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection

Locate Starter:
- The starter motor is located near the transmission. Remove any covers if necessary.
Check Connections:
- Inspect the wiring and connections to the starter for damage or corrosion.
Test Starter:
- Use a multimeter to check for voltage at the starter terminal while a helper turns the ignition key. If voltage is present and the starter does not engage, replace the starter.
Remove and Replace Starter (if needed):
- Disconnect the electrical connections from the starter.
- Remove the mounting bolts using a socket set.
- Install the new starter and torque the bolts to manufacturer specifications (typically around 10-15 lb-ft).
- Reconnect the electrical connections.
