02830 - Control Circuit for CAN Isolator for Driver Assistance Systems

02830 - Control Circuit for CAN Isolator for Driver Assistance Systems: Electrical Fault in Circuit

Possible Causes

  • Supply Voltage insufficient
  • Control Module Coding incorrect
  • Incorrect Control Module installed

Possible Solutions

  • Check Control Module Power Supply
  • Check Control Module Coding (see Vehicle specific Diagnostic Procedures).
  • Check CAN-Databus Powertrain Cut-Off Relay (J788)
    • Check Measuring Value Blocks (MVB)
    • Perform Output Test and check for an audible noise while the Relay is being actuated.
  • Check if Control Module (Part Number) fits the Car's Equipment

Special Notes

  • When found in VW Passat (3C): CAN-Gateway, check Measuring Value Block (MVB) 002.3 while cycling the Ignition. It should change between active and passive.
  • When found in the VW Passat (3C): CAN-Gateway after module replacement, see if address 4F-Centr. Electr. II is installed. If it is, that may be a virtual address in the new CAN Gateway and therefore need to be coded.
