Redundant calculation failure
Step-1: Perform a Klemme-15 reset (Ignition reset). Step-2: Flash the valid hex file if the DTC is still active. Step-3: 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.System state: NMWait, PreDrive, DriveDown, DriveUp, PostRun, Off, Error, Flash, LowVolt. 2.System voltage is above 6v. 3.System voltage is below 42v.
1. Defective powerpack when DTC stays always active. 2. Internal SW issue
