TAS sensor steering angle signals not valid
Step-1: Check the Torque and Angle sensor connections to the powerpack. Step-2: Replace the cable connecting the sensor to the powepack. Step-3: Perform a Klemme-15 reset (New Ignition cycle). Step-4: Replace the servo unit (powerpack and sensor unit) if the SPN is still active.
What you'll see
Not applicable
System reaction
Set the Yellow Lamp to "On". Set the signal EASState to ERROR. Set the EPS motor torque to 0 Nm. Electronic steering system is inactive. The software endstops are deactivated. DTC, KFC_ERROR_MODE_ACTIVE is set ACTIVE in the same Klemme-15 cycle. ActualSteeringMode signal stay in ASM mode. Steering gear operational mode is in Disable Steering gear degradation reason is in Internal Fault Note:ASM functionality deactivate
