Trouble shooting program EDC
Relay Delay Time check: Engine Stop via Voltage monitoring (Test 38)
Failure Code (Fendt):
1.2.99
Text-module
Failure location (MAN):
99
Text-module
Failure display :
Message on Dashpanel
Text-module
Failure path:
Status Engine stop via Voltage monitoring
Text-module
Consequences:
Max Speed reduced to 1900 Rpm
Torque reduced down to 25-40%,
Text-module
Function:
A Failure will be simulated intentionally During Time delay (Threshold Values). If the expected Speed
Loss does not occur, then Failure Code will be emitted
Text-module
Possible Origin:
Wiring discontinuity between EDC Control Module and Injection Pump, EDC Control Module Failure,
Injection Pump 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 Delay Time failures, Bewel Pinion 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 Solution Paths in Delay time will then be considered as Failed, since
speed does not decrease fast enough (vehicle is still moving).

Failure Conditions: If speed does not
drop below 300 Rpm within 10 seconds,
Failure Code will be emitted
- Document failure ( including atmo-
spheric parameters) using FENDIAS
- Start Engine several times ( 7 times),
in order to delete Failure Codes.
- Keep Engine at least 5 seconds at
Standstill between 2 start trials
- Delete Failure Code Memory with
FENDIAS
- Check again with FENDIAS
- Check MAB Signal (Connection
Control Module to Pump) if additio-
nally Failure Codes 1.2.9B or 1.2.A6
are occurring
- If Failure persists, Replace EDC
Control Module
Injection Pump
- Record Failure and ambient Para-
meters with FENDIAS
- Start Engine several times ( 7 times),
in order to delete Failure Codes.
