  2. Read out fault memory
  3. Eliminate cause of damage.
  4. Disconnect battery negative terminal
  5. Make sure that no safety-related system according to circuit diagram (e.g. antilock braking system, active rear-axle kinematics, airbags, etc.) are influenced. Otherwise replace faulty wiring harness or use repair cable (sourcing reference: BMW Parts Service)
  6. Carry out function test and read out fault memories again
