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.
Step2. Input Sensor Value
Adaptation >> Read by list >> Selected “Steering Angle Sensor” >> Input Matched value: 0 >> Save
Adaptation success!
Go back to read DTC again.
There’s no DTC. Trouble code has been cleared.
This is how to solve the VW 00778 sensor problem with X-431 Pad VII, all systems are back to normal!
