Checking Residual Flow 0 Setting (Test 34)
Failure Code (Fendt):
1.2.C8
Text-module
Failure location (MAN):
C8
Text-module
Failure display :
Message on Dashpanel
Text-module
Failure Path:
CAN-Signal (Fuel Flow, value transmitted via CAN-Bus to Pump)
LDF
NBF
Text-module
Consequences:
Engine stops, since calculation of Fuel Flow is not accurate
Text-module
Possible Origin:
Wiring discontinuity, Short Circuit, Control Module failure (XXXX), Needle Motion sensor (XXXX)
Failure, Intake pressure Sensor (XXXX) failure
Text-module
Remark 1:
Before Replacing any Pump or Control Module, failure Codes must l be analyzed and then deleted.
In case of several Failure Codes, check first the Test procedures wich are not requesting a replacement
of the Control Module or of the pump.

Injection Pump
Failure conditions: If in spite of Setting "
Fuel Flow =0", Speed is higher than 700
Rpm, Intake pressure > approx. 300
mbar and Needle motion Sensor Signal
are identified, failure Code will be emit-
ted.
- Record Failure and ambient Para-
meters with FENDIAS
- Delete Failure Code Memory with
FENDIAS
- Check again with FENDIAS
- - If failure persists, Replace injection
