VehicleInfo1Prop - Missing message
Check the COO for DTCs. • If DTCs cannot be read from the COO: - check CAN connection to COO unit and DAS (vehicles with DAS). - check power supply and ignition signal to COO and DAS (vehicles with DAS). • Check wiring and connectors for the 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 Environment Sensor CAN bus (vehicles without DAS), Sensor CAN bus (vehicles with DAS) and CAN5 bus (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 COO and DAS (vehicles with DAS) 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 VehicleInfo1Prop_K has been absent for 100 ms.
• Faulty COO unit or DAS unit (vehicles with DAS). • Open circuit on the Environment Sensor CAN bus (vehicles without DAS), Sensor CAN bus (vehicles with DAS) or CAN5 (vehicles with DAS).
