Invalid steering angle values from TAS sensor.
Step-1: Check the Torque and Angle sensor connections to the powerpack. Step-2: Replace the cable connecting the sensor to the powerpack. Step-3: Perform a Klemme-15 reset (New Ignition cycle). Step-4: Replace the servo unit (powerpack and sensor unit) if the DTC is still active.
What you'll see
The driver might detect reduction in Assistance/Hard Steering due to reduced electrical support.
System reaction
Set the Yellow Lamp to "On". Set the signal EASState to ERROR. Set the EPS motor torque to 0 Nm. Electric steering system is inactive. Software endstops are deactivated. DTC, KFC_ERROR_MODE_ACTIVE is set ACTIVE in the same Klemme-15 cycle.
Diagnostic depth
The DTC will set during the following condition: 1. Steering angle sensor signals are invalid. 2. Steering angle sensor signals are outside of range. 3.system state: DriveDown, DriveUp, PostRun 4.system voltage is above 6v. 5.system voltage is below 42v.
1. Torque and Angle Sensor unit is defect/disconnected. 2. Connecting cable from the sensor to the powerpack is defect. 3. Defective powerpack.
