841008778 - E8010 MULTIPLE DIAGNOSTIC CONNECTOR DESCRIPTION (Automatic Transmission )

Description

The car is fitted with numerous electronic control units that peform self-diagnostic functions.It is possible to link up to each unit via a tester (Examiner or similar). This can be used to read self-diagnostic data (parameters and errors) or carry out active diagnosis.All conections relating to the diagnostic function (on line K, and via B Can network) flow into the connector of the EOBD ( European On Board Diagnosis ), in accordance with directive 98/69/CE ( EURO3 ) - ISO standard J1962, centralised on Body Computer connector I.Nodes connected to the network are diagnosed via the B CAN network while the dynamic car control network is diagnosed by a specific K lines.The following are controlled via B CAN line:

  • Climate control unit;
  • the steering geometry control unit;
  • driver''s door control unit;
  • passenger door control unit;
  • the roof control unit;
  • the info-telematic control unit.
  • the passive entry control unit;
  • the steering lock control unit;
  • the luggage compartment control unit;
  • the steering wheel control unit;
  • the parking sensor control unit;
The Body Computer also manages signals from control units connected to the C Can line, ( See Wiring diagram E1050 CAN lines ), in order to check that the units are working properly.    See E1050 CAN CONNECTION LINESThe following control units are connected to the body computer via the C-CAN:

  • the engine management control unit;
  • the braking system control unit;
  • the braking system check control unit;
  • the electric braking control unit;
  • the slewing control unit;
  • the steering angle control unit;
  • the steering geometry control unit;
  • the cruise control system control unit.
The following nodes are connected to the Body Computer via the B-CAN:

  • the climate control system control unit;
  • the steering wheel node control unit;
  • the driver''s door control unit;
  • the passenger door control unit;
  • the roof control unit;
  • the luggage compartment control unit;
  • the passive entry control unit;
  • the parking sensors control unit;
  • the instrument panel control unit;
  • the steering lock control unit;
  • the info-telematic control unit.
the following are monitored via diagnostic line K:

  • the electric braking control unit;
  • the Servotronik control unit;
  • the headlamp alignment control unit;
  • the Air Bag control unit;
  • the adaptive cruise control control unit.
  • the braking system check control unit (brake assistance);
  • Supplementary heater control unit;
  • the engine management control unit;
  • the braking system control unit;
