Differential lock front axle 2 sensor lost.
â–¶ How to fix

What you'll see
No driver-visible symptom recorded.
System reaction
The driver is given an indication that the differential lock has been disengaged. The system attempts to maintain the differential lock in engaged position.
Diagnostic depth
Detection
The position sensor changes the status from active to passive even though the solenoid valve is still activated. This fault code is generated only if the supply air pressure from the APS-system is normal.
Possible cause
This fault code is generated, e.g. if the compressed air supply to the control cylinder is stopped or if there is a loose cable or sensor.
