Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, jumper cables.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative terminal of the battery for safety.

2. Battery Inspection and Replacement

Inspect the Battery:
- Clean any corrosion from the terminals using a wire brush.
- Tighten any loose connections to ensure a good electrical contact.
- If the battery voltage is low (below 12.4 volts), proceed with replacement.
Replace the Battery (if necessary):
- Disconnect the positive terminal first, then the negative terminal.
- Remove the battery hold-down bracket and lift the battery out of the tray.
- Install the new battery, ensuring it is securely in place.
- Connect the positive terminal first, then the negative terminal.
- Ensure connections are tight and secure.

3. Starter Inspection and Replacement

Inspect the Starter:
- Locate the starter motor (usually near the transmission).
- Check for any loose wires or connections to the starter.
- If the starter shows signs of damage or does not respond to a jump-start, it may need replacement.
Replace the Starter (if necessary):
- Disconnect the battery again for safety.
- Remove the wiring harness from the starter (note the connections for reinstallation).
- Remove the starter mounting bolts with a socket set.
- Carefully extract the starter from the engine bay.
- Install the new starter by reversing the removal steps, ensuring all connections are secure.
- Reconnect the battery.
