what does it mean when my Tesla Model S Plaid/Refresh (2021-present) shows error code B0111

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, screwdrivers).
• Disconnect the vehicle's 12V battery to ensure safety while working on the airbag system.
• Wait at least 3 minutes after disconnecting the battery to allow the airbag system to discharge.

2. Inspect and Repair Airbag Connector

• Locate the driver's side airbag connector under the steering column.
• Carefully disconnect the airbag connector.
• Inspect the connector pins for damage or corrosion; clean or replace as necessary.
• Reconnect the airbag connector securely.

3. Replace Airbag Module (if required)

• If the inspection indicates the airbag module is faulty, remove it by:
  • Unscrewing any retaining screws or bolts securing the airbag module.
  • Carefully lifting the module out of its mounting location.
• Install the new airbag module by reversing the removal steps.
• Ensure the new module is compatible with the vehicle's system.

4. Reconnect Battery and Clear Codes

• Reconnect the 12V battery.
• Use an OBD-II scanner to clear any error codes from the system.
• Verify that the airbag warning light is off after clearing the codes.
