ServTronic Electric Power Steering Controller Box 2013-2021 BRZ / 2013-2016 FRS / 2017-2021 86

Electric power steering uses an electric motor to assist the steering. A computer module (ECU) receives information from several sensors and decides which level of assistance the electric motor should deliver to the steering. When you install an electric steering column from Subaru BRZ or Scion FRS or Toyota 86 to your vehicle it won´t work because the ECU doesn´t receives information. That´s why you need this controller unit. It sends information to the ECU according to the position of the knob. 

So, the position of this knob will determine the steering assistance level. 

How to adjust steering assistance:

• Adjustment knob turned fully anti-clockwise - minimum steering assistance.

• Adjustment knob turned fully clockwise - maximum steering assistance.

• Between this two points, you have various intermediate steering assistance levels.

Please check the photos attached and compare them with your used steering column. Make sure they are similar before buying our Kit.
