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.
