how to resolve SRS system problems on Tesla Model S Original (2012-2020)

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, torque wrench, socket set, and safety goggles.
• Disconnect the vehicle battery and wait at least 10 minutes to ensure any residual charge is dissipated before working on the SRS system.

2. Reset SRS Error Codes

• Connect the OBD-II scanner to the vehicle's port.
• Navigate to the SRS system menu and select the option to clear error codes.
• Confirm the codes are cleared and disconnect the scanner.

3. Inspect and Repair Wiring

• Remove necessary panels to access the airbag control module and wiring harness.
• Use a multimeter to check for continuity and voltage in the wiring.
• Repair or replace any damaged wires or connectors found during inspection.
• Ensure all connectors are securely fastened.

4. Replace Faulty Components

• If any SRS components (sensors, control module, airbags) are determined to be faulty, follow these steps:
  • Disconnect the battery again before replacing any airbag.
  • Carefully remove the defective component, taking care not to deploy the airbag.
  • Install the new component according to manufacturer specifications.
  • Torque all bolts to the specified values (usually found in the service manual).

5. Reconnect Battery and Final Check

• Reconnect the vehicle's battery.
• Perform a system check with the OBD-II scanner to ensure no error codes are present.
• Conduct a function test of the SRS system to verify all components are operational.
