Trouble shooting program EDC
Test: Engine Stop via CAN Setting "Fuel Flow 0" (Test 7)
Failure Code (Fendt):
1.2.92
Text-module
Failure location (MAN):
92
Text-module
Failure display :
Message on Dashpanel
Text-module
Failure path:
EDC Control Module, Injection pump
Text-module
Consequences :
Full Power Fuel Flow reduced by 25-40%
Reduced max. Speed to 1900 Rpm
Text-module
Function:
During Relay Delay time Fuel Flow 0 is set. If the expected Speed drop does not occur, Failure Code
will be emitted.
Text-module
Possible Origin:
EDC Control Modue failure, Injection Pump Failure, Bewel Pinion Speed Sensor failure, Engine Stop
Path 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.
Text-module
Remark 2:
In Case of Relay Delay Time failures, Bewel Pinion Speed Sensor must be checked.
Reason: If speed Display shows 0 km/h while tractor is moving, and Ignition will be switched "OFF",
then Delay Time occurs. Several Engine Stop Paths may be identified as failed, since speed does not
drop fast enough (still moving tractor).

Trouble shooting
EDC Control Module
Tractor at standstill (0 km/h) Engine
speed 800 Rpm, start seven times En-
gine in order to delete Failure codes. En-
gine must stand still for at least 5 se-
conds between 2 Starting trials.
- Record Failure and ambient Para-
meters with FENDIAS
- Delete Failure memory with FEN-
DIAS
- Check again witth FENDIAS
- If Failure persists, replace EDC Con-
tol Module
Engine Stop Paths
Tractor at standstill (0 km/h) Engine
speed 800 Rpm, start seven times En-
gine in order to delete Failure codes. En-
gine must stand still for at least 5 se-
conds between 2 Starting trials. Check
Speed Sensor Signal with FENDIAS.
Injection pump
- Record Failure and ambient Para-
meters with FENDIAS
- Delete Failure memory with FEN-
DIAS
- Check again witth FENDIAS
- If Failure persists, replace Injection
