2008 yaris with intermittent power failures please help

[08yarisbroken]

would the ign2 relay control all the key off power to the car too?

The headlight and dome lights didn't work when its showing its problem too.

Ign2 controls power to these also I take it..

If so for whatever the cost is I'm going to have to try that first Ive read your prior posts to say its about $110. or so.

Is the ecm then cleared of this being the fault. And is it coded or matched to the car?

I thank you sooooo much.. I feel like a jerk because i can't fix or find this problem asap. I don't want her safety jeopardized.

Actually the IG2 relay would not come into play for the dome light. The ECM also could not cause this, so I would actually check the battery terminals for corrosion and the large connectors that plug into the back of the positive battery terminal for corrosion as well.

ok i will inspect the wire and fuse area near the battery and firewall.

this car i believe was preowned in oregon and I can see a light coating of white corrosion all over the engine bay.

ty for your help

Sounds like the battery posts not sparking, need to remove them and clean them with sand papers.. posts and all..
