Moisture Ingress & Corrosion Water ingress, condensation or connector corrosion can interrupt communication and damage the internal electronics of the DEM module. 2. Control Valve or Hydraulic Faults Related Haldex valve faults can overload the control strategy and trigger repeated AWD or anti-skid warnings. 3. Internal Electronic Failure Age, vibration and thermal cycling can cause internal circuit or memory problems, leading to intermittent AWD operation or complete loss of rear drive control. 4. Wiring or Power Supply Problems Damaged wiring, weak power supply or poor connector contact can create no-communication errors and unstable module behaviour.
