how to reset my Tesla Outback's computer after a battery change

Solution

1. Preparation

• Gather necessary tools including an OBD-II scanner and basic hand tools (wrenches, socket set).
• Ensure the vehicle is parked on a level surface and the battery is fully charged before beginning.

2. Disconnect and Reconnect Battery

• Step 1: Open the hood and locate the battery.
• Step 2: Use a wrench to loosen the negative terminal clamp and remove it first.
• Step 3: Repeat for the positive terminal, ensuring you do not touch both terminals simultaneously.
• Step 4: After waiting 5-10 minutes, reconnect the positive terminal first, followed by the negative terminal, tightening them securely.

3. Reset the Vehicle’s Computer

• Step 1: Insert the key fob or push the start button to power the vehicle on without starting the engine.
• Step 2: Wait for the dashboard to fully initialize, then press and hold the brake pedal.
• Step 3: Depending on the model, perform a soft reset by pressing and holding the control buttons (usually the volume and scroll wheel) until the screen reboots.
• Step 4: If necessary, use the OBD-II scanner to clear any error codes that appeared during diagnostics.
