Purge Solenoid Valve Status
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
Pressure regulation is still possible, but regeneration cannot be started. The system is not in degraded mode. The pressures are still measured and transmitted. The following plausibility faults will be disabled: - Not possible to switch off the compressor - No pressure drop during regeneration - Sensor plausibility check
Diagnostic depth
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.
The high side driver can not be switched on due to an internal electrical fault.
