This procedure will be necessary if replacing the Master or Slave motors when they start acting crazy. There is an ECU contained in each wiper Motor. The master ECU on the driver side controls the slave ECU on the passenger side. It is important to diagnose the wiper ECUs first with Diagbox, before deciding which of the wiper motors is at fault - because the one acting up may not be the faulty one if it is getting incorrect data sent form the opposite ECU.
