Solution

1. Preparation

Tools Required: Multimeter, OBD-II scanner, jumper cables, basic socket set.
Ensure the vehicle is in a safe location with the ignition turned off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection and Replacement

Check Battery Voltage
- Connect the multimeter to the battery terminals.
- If the voltage is below 12.4 volts, proceed to the next step.
Check Battery Terminals
- Inspect the connections for corrosion; clean with a wire brush if necessary.
- Reconnect the terminals securely.
Jump-Start the Vehicle
- Connect jumper cables to the discharged battery, ensuring correct polarity.
- Start the donor vehicle and let it run for a few minutes.
- Attempt to start the Tesla. If it starts, the battery may need replacement.
Replace Battery
- If the battery is faulty, remove the old battery by unbolting the hold-down bracket.
- Replace with a new battery of the same specifications (12V, compatible with Tesla).
- Reconnect the battery terminals (positive first, then negative) and secure the bracket.

3. Starter and Ignition System Inspection

Check Fuses
- Locate the fuse box and check fuses related to the ignition and starter (refer to the owner's manual).
- Replace any blown fuses with the correct amperage rating.
Inspect Starter Motor
- If the vehicle still does not start, locate the starter motor.
- Check for loose connections or damaged wires.
- If necessary, test the starter by applying voltage directly to its terminals; replace if faulty.
