Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and cleaning supplies.
  • Ensure the vehicle is in park (for automatic) or neutral (for manual) and the parking brake is engaged.
2. Battery Inspection and Replacement

  1. Disconnect the Battery

    • Use a socket set to remove the negative terminal first, followed by the positive terminal.

  2. Clean Battery Terminals

    • Use a wire brush to clean any corrosion from the battery terminals and cable connectors.

  3. Test or Replace the Battery

    • If the battery voltage is below 12.4 volts, recharge or replace the battery.
    • To replace, remove the battery retaining bracket and lift the battery out. Install the new battery in reverse order.
3. Starter Motor Inspection

  1. Access the Starter Motor

    • Raise the vehicle and secure it with jack stands.
    • Remove any underbody covers or shields that obstruct access to the starter motor.

  2. Check Connections

    • Ensure all electrical connections to the starter motor are secure and free of corrosion.

  3. Test the Starter Motor

    • Use a multimeter to check for voltage at the starter solenoid while someone attempts to start the vehicle. If no voltage is present, further investigate the ignition switch.

  4. Replace the Starter Motor

    • If the starter motor is defective, remove the mounting bolts and electrical connections, then replace it with a new unit.
4. Final Assembly
  • Reassemble any components or covers removed during access.
  • Reconnect the battery terminals (positive first, then negative).
