Solution

1. Preparation

Ensure the vehicle is in park and the ignition is off.
Gather tools: multimeter, jumper cables, socket set, and OBD-II scanner.

2. Battery Inspection and Replacement

Check Connections:
- Remove the negative (-) battery cable first, then the positive (+) cable.
- Clean any corrosion from the terminals using a wire brush.
Test Battery:
- Connect the multimeter to the battery terminals. If the voltage is low (below 12.4 volts), proceed to battery replacement.
Replace Battery:
- Remove the old battery by unscrewing the hold-down bracket and lifting it out.
- Install a new battery (ensure it is compatible with the Tesla Outback).
- Connect the positive (+) cable first, then the negative (-) cable. Ensure they are tight.

3. Starter Motor Inspection

Access Starter:
- Raise the vehicle if necessary and locate the starter motor.
Inspect Wiring:
- Check wiring for loose connections or damage; repair or replace as needed.
Test Starter:
- Using the socket set, remove the starter. Test it by applying direct battery voltage to the terminals (be cautious of sparks).

4. Reassemble and Test

Reinstall the starter motor and battery.
Ensure all connections are secure and components are properly placed.
Attempt to start the vehicle.
