Solution

1. Preparation

Tools Required: Multimeter, jumper cables, socket set, torque wrench, safety gloves
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Battery Inspection and Replacement

Check Battery Condition
- Remove the negative terminal using a socket wrench.
- Remove the positive terminal.
- Inspect the battery for signs of swelling, leaks, or damage.
Clean Battery Terminals
- Use a wire brush to clean any corrosion from the battery terminals and cable ends.
- Reconnect the positive terminal first, followed by the negative terminal.
Test Battery Voltage
- Use a multimeter to measure the battery voltage. If below 12.4 volts, charge the battery or replace it.
- If the battery is over 3 years old, consider replacing it regardless of the voltage.

3. Starter Motor Inspection and Replacement

Access Starter Motor
- Raise the vehicle and secure it on jack stands.
- Locate the starter motor (typically near the transmission).
Test Starter Motor
- Disconnect the wiring harness from the starter.
- Use a multimeter to check for voltage at the solenoid terminal when the key is turned to the start position.
- If voltage is present but the starter does not engage, replace the starter motor.
Remove and Replace Starter Motor
- Remove the mounting bolts using a socket set.
- Carefully remove the starter from the engine bay.
- Install the new starter motor and secure it with the bolts, torquing them to the manufacturer specifications (usually around 30 Nm).

4. Verify Connections

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