General: Help with Vida codes and parasitic battery drain

[Moryakov]

Hi,

I’ve just gotten my first car off of my parents, a year 2000 P2 2.4 V70. They’d had it since 2012. It has been suffering with a parasitic battery drain for a while now and I recently got a cheap dice unit and decided to initialise the windows (which worked perfectly) and read the codes to see if anything was hinting at the battery drain issue. There’s quite a few codes which I don’t really understand, I don’t know how to tackle them. And one of them in the DDM seems like it may be related to the battery drain issue, but I don’t know how to go about testing this.

The codes are:

DDM-0005 Power window motor M+ or M- signal missing
DDM-0049 Control module internal fault
ECM-9150 Throttle Position (TP) sensor 1 - faulty signal
CCM-E003 Configuration fault faulty configuration
CEM-1A61 Communication with TCM control module Signal Missing
ECM-A00B Transmission Control Module (TCM) communication- faulty signal

Any help on understanding these codes or testing the window for a parasitic drain is appreciated,

Thanks.

Erase all the codes, clear the Vehicle Profile and read the car again, selecting "Update" when prompted before seeing the most recent and actual fault code situation in the Initial State tab.
Click on each code individually then View Information bottom left for a description of the code, its circumstances and possible causes and fixes.

That said, for a parasitic drain there's really no substitute for old school connecting of a multimeter in series with the battery negative lead to measure the actual drain and targeted removal of fuses from active circuits only.

Of the many many things Vida is brilliant for, diagnosing parasitic drains isn't one.
Consider also the alternator diode pack allowing a reverse current drain, once again tested with a multimeter.
