Trouble shooting program EDC
Relay time Delay: Engine Stop via Relay "Soplenoid valve " K021 (Test 18)
Failure Code (Fendt):
1.2.A2
Text-module
Failure location (MAN):
A2
Text-module
Failure display :
Message on Dashpanel
Text-module
Failure path:
EDC Control Module , Driving Speed , Injection Pump, Relay
Text-module
Consequences:
Full Power Fuel Flow reduced by 25-40%
Reduced max. Speed down to 1900 Rpm
Engine Stop via Pump Relay is not possible
Text-module
Function:
Pump Relay will be disconnected , Engine will stop.
Text-module
Possible Origin:
EDC Control Module Failure, Bewel Pinion Speed Sensor not plausible, 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).

Use wiring diagrams wich are corresponding to the tractor

- Record Failure and ambient Para-
meters with FENDIAS
- Start Engine several Times ( 7 ti-
mes), innorder to delete Failures.
- Engine must be at a Standstill for at
least 5seconds between 2 Start trials
- Delete Failure Code Memory with
FENDIAS
- Check again with FENDIAS
- If failure persists , Replace Pump
