EDC BUS-System
See also : Chapter 9700 Reg. A "Concept of electronics" Fav 900/23/...)
Data communication between Engine control module MSG (A021) and pump control module
PSG (A021) occurs via EDC-CAN-BUS (Diagram chapter 9000 Reg.C Sheet 33 ; EDC Engine control)
Text-module
Engine control module communicates via transmission BUS (G-BUS) and via comfort control module
(A002) with the Comfort-BUS (K-BUS)
Error codes are displayed on the dashpanel (A007) via BUS System.
(Diagram "Comfort-BUS and Transmission-BUS" ; Chapter 9000 Reg.C ; Sheet 21 and Sheet 26)
Text-module
The Engine control module is equipped with a diagnostic connector (X412)
This connector allows the reading of the parameters from the Engine and Injection pump control
modules.
"EDC - Diagnostic"
Note:
The Injection pump control module and the injection pump are matched.
For this reason replace only the complete injection pump.
In case of replacement of the engine control module by a module wich does not correspond to
the engine type, all parameters (max. torque) will be limited and set for Fav. 916 ( Error Code
1.1.A0 )
This egually valid for erroneous End Of Line programming.
