Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, OBD-II scanner.
Ensure the vehicle is in park or neutral, and the parking brake is engaged.
Disconnect the negative battery cable to ensure safety while working.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from the terminals using a wire brush.
- Ensure terminals are tightly connected to the battery posts.
Test Battery Voltage
- Reconnect the negative cable and measure the voltage with a multimeter.
- If the voltage is below 12.4 volts, proceed to replace the battery.
Replace Battery
- Using a socket set, remove the battery hold-down clamp.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and install the new one, connecting the positive terminal first, then the negative terminal.
- Tighten the hold-down clamp securely.

3. Starter Motor Inspection and Replacement

Verify Starter Operation
- Reconnect the battery and check for voltage at the starter solenoid while attempting to start the engine.
- If no voltage is present, check the ignition switch and associated fuses.
Replace Starter Motor (if necessary)
- Disconnect the negative battery cable.
- Remove any components obstructing access to the starter motor (e.g., air intake hoses).
- Disconnect the electrical connectors from the starter motor.
- Remove the mounting bolts using a socket set and take out the starter motor.
- Install the new starter motor, reconnect the electrical connectors, and secure it with the mounting bolts.
- Reconnect the negative battery cable.
