Problems with drain on 2001 V70 non-turbo FWD. What I've done so far is do a voltage drop test on each fuse and identified the main problem with fuse #25 (CEM, SRS, ECM, ignition switch) and another smaller drain with fuse #28 (roof lamps, courtesy lamp, UEM, garage door opener). With the multimeter set on 200M scale the reading on fuse 25 is 00.4; reading on fuse 28 is 00.1. Not sure how to interpret these readings or what to do next. Any suggestions appreciated. THANKS!

 

I don't know the voltage drop test procedure. I should.

What you can't do is energize only those circuits then try to eliminate (unplug) it's components individually to see if you effect current flow to the ground.

When companies like XeMODeX rebuild CEMs and ECM's I wonder how many times it's this problem-internal faults I assume.
