Step-1: Perform a Klemme-30 reset (Power Reset). Step-2: Check the CAN connection. Step-3: Check the connections to powerpack. Step-4: Check the Sending ECU(s).
What you'll see
The driver might detect reduction in assistance due to constant vehicle speed value of 90Kmph.

Diagnostic depth
The DTC will set during the following condition: 1. System state Signal, EASState: NMWait, PreDrive, DriveDown, DriveUp. 2. Calculated vehicle speed is outside the valid range i.e. outside the range, [-20 kmph, 200kmph]. 3. Klemme-15 (Ignition key) is on. 4. System voltage is above 6v. 5. System voltage is below 42v. Note: Certain gearboxes allows reversing more than -20 km/h this means that the EAS will still set DTC even though the value of VehicleGroundSpeed and FrontAxleSpeed is valid.
1. Faulty CAN Bus data transmission. 2. The sending ECU is defect.
