VW-AUDI Scope patterns for CAN

I was connected to an Audi yesterday. Parasitic drain. CAN goes to sleep okay. Then the cluster comes alive and drains the battery.

We connected using the Universal scanner from Taiwan. We used the VAS 19.01 to demonstrate.

The software recommends the Measurement module as it wants you to use the oscilloscope.

Then it pops to the next page, where it shows you these known patterns.

How else would you get this information? I made a mistake on 3 or 4, same image different description.

CAN okay CAN sleep mode open CAN low open circuit CAN high Short CAN High to Low Short CAN High to negative Short CAN High to positive Short CAN Low to negative Short CAN Low to positive
