CAN Bus DDE

Data exchange between the following control modules takes place via the CAN bus:

• DDE control module
  
• Instrument cluster control module
  
• ABS/DSC control module
  
• Steering angle sensor
  

Troubleshooting

Following faults are recognized concerning the CAN bus:

• Hardware fault on DDE control module (CAN Controller)
  The affected values are replaced by substitute values.
  
• Communication fault between the control modules
  Consequence: The functions whose messages are affected by failure of the CAN bus fail, e.g. ASC and engine drag torque control.
