Active return plausibilization error
Step-1: Set Vehicle speed to 0. Step-2: Perform a Klemme-15 reset (Ignition reset). Step-3: Flash the valid hex file if the DTC is still active. 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.Active return failure integration plausibilization value >= 2000. 2.System state: DriveDown, DriveUp. 3.System voltage is above 6v. 4.System voltage is below 42v.
1. Invalid steering angle. 2. Invalid steering angle speed. 3. Active return torque offset greater than threshold for 200 ms towards the end-stops.
