Solution

1. Preparation

Gather tools and materials: Multimeter, socket set, torque wrench, OBD-II scanner, wire brush, and protective gloves.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion on the battery terminals with a wire brush.
- Tighten any loose connections.
Test Battery Voltage
- Reconnect the battery and use a multimeter to check voltage.
- If the voltage is below 12.4 volts, consider jump-starting or replacing the battery.
Replace Battery (if necessary)
- Remove the old battery by unbolting the hold-down bracket and disconnecting the negative cable first, then the positive cable.
- Install the new battery by connecting the positive cable first, followed by the negative cable.
- Tighten the hold-down bracket securely.

3. Starter Motor Inspection and Replacement

Check Starter Motor Connections
- Ensure that the starter motor connections are clean and secure.
- If the connections are corroded, clean them and reconnect.
Test Starter Motor Functionality
- If the starter does not engage when connected directly to the battery, it may need replacement.
Replace Starter Motor (if necessary)
- Disconnect the battery again.
- Remove the starter motor from the vehicle by unbolting and disconnecting any electrical connectors (follow the vehicle’s service manual for specific bolt locations).
- Install the new starter motor, ensuring all connections are secure and bolts are properly torqued.
