Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, and OBD-II scanner.
Ensure the vehicle is in park (or neutral for manual transmissions) and the parking brake is engaged.
Disconnect the battery negative terminal to avoid any electrical shorts.

2. Battery Inspection and Replacement

Check Battery Condition:
- Clean any corrosion from the battery terminals using a wire brush.
- Ensure that the connections are tight.
Replace Battery (if voltage is below 12.4 volts):
- Remove the negative terminal first, followed by the positive terminal.
- Remove the battery hold-down bracket and lift the battery out of the tray.
- Place the new battery in the tray, securing it with the hold-down bracket.
- Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection

Remove Starter Motor:
- Disconnect the negative battery terminal again.
- Locate the starter motor, typically near the transmission bell housing.
- Unplug the wiring harness from the starter.
- Remove the mounting bolts using a socket set and carefully take out the starter.
Test or Replace Starter Motor:
- Bench test the starter motor using a battery to check functionality.
- If faulty, replace the starter with a new or refurbished one.
- Reinstall the starter by reversing the removal steps and ensure all bolts are torqued to manufacturer specifications.
