Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from the terminals using a wire brush.
Test and Replace:
- If the battery voltage is below 12.4 volts, charge or replace the battery.
- Install a new battery (if needed) and torque the terminals to manufacturer specifications (usually 10-15 ft-lbs).

3. Starter Motor Inspection and Replacement

Remove Starter:
- Locate the starter motor (usually near the transmission).
- Disconnect the electrical connectors and remove the mounting bolts using the socket set.
Inspect Starter:
- Bench test the starter by connecting it to a battery; it should engage and spin.
- If faulty, proceed to replace.
Install New Starter:
- Position the new starter in place, securing it with mounting bolts (torque to manufacturer specifications).
- Reconnect electrical connectors.

4. Final Assembly

Reconnect the battery terminals (positive first, then negative).
Ensure all tools are removed from the engine bay and close the hood.
