Trouble shooting program EDC
Plausibility Engine Stop via Solenoid valve (MAB-Signal) (Test 12)
Failure Code (Fendt):
1.2.9B
Text-module
Failure location (MAN):
9B
Text-module
Failure display :
Message on Dashpanel
Text-module
Failure path:
Status "Engine Stop via Solenoid valve"
Text-module
Consequence:
Full Power Fuel Flow reduced by 25-40%
Reduced max. engine speed to 1900 Rpm
Text-module
Funktion:
Check wether MAB-Status in Pump Control Module and EDC Control module ar identicals
Text-module
Possible Origin:
Wiring disruption between Pum Control Module and EDC Control Module
Signal failure "Solenoid Valve Engine Stop" on EDC Control Module.
Injection Pump (Control Module ) failure
Text-module
Remark1:
Before replacing the Injection Pump or Pump Control Module , delete Failure Code memory and
analyse the failures.
Perform first all tests corresponding to failure Codes wich do not make Injection Pump or Pump Control
Module replacement necessary.
Text-module
Remark 2:
By Failures in Delay Time, check egually Signal of Bewel Pinion Speed Sensor (B015)
Reason: If speed Display shows 0 km/h while tractor is moving, and Ignition will be switched "OFF",
then Delay Time occurs.
The various Solution paths can be identified as Failures , since Engine speed does not decrease
sufficiently fast (while tractor is moving).

EDC Control Module
Check connection Pin A20 on Control
module A021, Connector X047 with Pin
5 , A020 Connector X046, VP 44, Wire
WM1709
- Record Failure and ambient Para-
meters with FENDIAS
Delete Failure Code Memory with
FENDIAS
- Check again with FENDIAS
- If Failure persists, replace EDC Con-
trol Module
Injection Pump
Connection Pin A20 on EDC Control Mo-
dule A021, Connector X047
- Record Failure and ambient Para-
meters with FENDIAS
Check VP 44 with Pin 5, A020, Connec-
tor X046, VP 44
- Delete Failure Code Memory with
FENDIAS
Failure Conditions: none indicated
- Check again with FENDIAS
- Check Wires
- Check connectors
- if Failure persists, replace Injection
