I tried to get the codes, there are many faults but there is no communication with the ECU. The message says: communication Error: communication with control module interrupted, possible causes...
But I just notice the battery was very low on voltage, 9.3V as per DAS, and 9.95V as per Fluke multimeter.

That may be the cause of all my problems, I will get the appropriate voltage and go on with the test.

Is it possible go get this kind of problem with a low voltage?

Thanks!
