Cartridge Solenoid Valve Status
â–¶ How to fix
Erase fault memory and check if fault is still present. If fault is still present exchange the ECU to fix the problem.
What you'll see
No driver-visible symptom recorded.
System reaction
Switching to second cartridge is not possible thus the system gets wet. Compressed air is only pumped through first cartridge, while regeneration can only be performed on second cartridge.
Diagnostic depth
Detection
Detection within 1,2 seconds after occurence of fault when the solenoid valve is switched-on. The fault is stored in the error memory if the condition is still existing after the validation time has elapsed. A re-testing is done every 1 second.
Possible cause
The high side driver can not be switched on due to an internal electrical fault.
