Trouble shooting program EDC
Relay Delay Time: Engine Stop with MAB-Signal (Test 30)
Failure Code (Fendt):
1.2.C5
Text-module
Failure location (MAN):
C5
Text-module
Failure path:
Status Engine Stop Via Solenoid Valve during Delay Time
Text-module
Consequences:
Max. Speed Reduced to 1900 Rpm
Full Power Fuel low reduced by 25-40%,
since MAB- Engine stop is not possible
Text-module
Possible Origin:
Bewel Pinion Speed Sensor Signal Failure (Display on Dashpanel "99,99 km/h")
PTO Drives Engine due to Implement inertia.
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

Signal Bewel Pinion
Speed Sensor (XXX)
Speed must be 0 kpH to be checked by
FENDIAS when Engine is Stopped
- Check speed Bevel pinion / Collec-
tor shaft
Injection pump
Failure Conditions: Failure Code will
be emitted if Speed does not drop below
300 Rpm within 10 seconds
- Record Failure and ambient Para-
meters with Diagnosic program.
- Start Engine 7 times in order to de-
lete Failure Codes.
- Engine needs to be at standstill for at
least 5seconds between 2 Start trials
- Delete Failure Code Memory with
FENDIAS
- Check again with FENDIAS Delete
Failure memory
- read out failure Memory
- If failure persists, Replace injection
Pump
