Function monitoring
â–¶ How to fix
- Check EGC4 - Change EGC4
What you'll see
No driver-visible symptom recorded.
System reaction
- Engine doesnt accept gas anymore - Irreversible safety-fuel-cutoff
Diagnostic depth
Detection
- fr_w>FRMX_UM OR fnsad_w>KLFNSMX_UM (factor for the regulation of lambda bigger than monitoring threshold level 2 or adaption after engine running greater than monitoring threshold
Possible cause
- Function monitoring: fault of ECG4 or sensor in mixture check - Engine control unit EGC4 defect
