Launch X-431 Fixed VW 00778 Steering Angle Sensor Error

The VW Scirocco has just been replaced with a steering module. Its sensor is working but has a trouble code that can't be cleared. The DTCs is "00778, steering angle sensor no signal/ communication". That means the CAN communication is not working well. So we're going to use Launch X-431 Pad 7 to fix the problem. If you have other X431 diagnostic tools like X431 PRO5 or X431 V+ may refer to the procedure as well.

Step1. Check Sensor Status

Firstly, do a quick diagnosis to check all data.

Confirm vehicle info.

Read data stream >> Read by list

Selected "Steering angle-sensor(G85), Calibration-Status(G85), Steering Angle-Speed, initialization-Status(G85)".

We can see the sensor is working fine.
