VDC2 - Missing message
Check the BMS for DTCs. • If DTCs cannot be read from the BMS: - check CAN connection to BMS and COO unit - check power supply and ignition signal to the BMS, COO and DAS (vehicles with DAS). • Check wiring and connectors for the Red CAN bus, Environment Sensor CAN bus (vehicles without DAS), Sensor CAN bus (vehicles with DAS) and CAN5 (vehicles with DAS). • Measure the resistance (with the battery disconnected) at Red CAN bus, Environment Sensor CAN bus (vehicles without DAS), Sensor CAN bus (vehicles with DAS) and CAN5 (vehicles with DAS). It should be approximately 60 ohm (one 120 ohm termination resistor in each end of the CAN bus).
What you'll see
No driver-visible symptom recorded.
System reaction
Functions dependent on information from BMS are degraded. Examples listed below. - target detection - target selection - path prediction - misalignment detection DIS2 will be degraded. DIS2 target output will be error.
Diagnostic depth
The DTC is set active if the CAN message VDC2_A has been absent for 100 ms.
• Faulty BMS, COO unit or DAS unit (vehicles with DAS). • Open circuit on the red, Environment Sensor CAN bus, Sensor CAN bus (vehicles with DAS) or CAN5 bus (vehicles with DAS):
