Cartridge Solenoid Valve Status
â–¶ How to fix
Check ECU, solenoid valve and connecting cable in between. Erase fault memory and check if the fault is still present. If nothing unusual could be detected replace the ECU.
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 0,2 seconds after occurence of fault when the solenoid valve is switched-off. 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 low side driver can not be switched off due to an electrical fault.
