Both lights on constant before speed indicate no power...OVP fuse is first suspect, fuse #7 is second.

Do you have 12V + at pin 16 of DM to ground?

Well, per the recommendations here I went back and investigated all the connections behind the battery. Part of the connector to the OBC had been disconnected and tucked away down under part of the battery tray. This car was diagnosed as having a bad OVP relay by a local shop with a bad reputation before I bought it...I suspect they disconnected it deliberately and were hoping to get the replacement cost out of the previous owner.

I didn't catch it when replacing the OVP because I didn't dig deep enough and didn't know these cars well enough to know how that connector works....though I thought it was weird that 3 of the pins from the relay weren't connected to anything!

So, now my ASR/ABS is working great, car is running well. Thanks!!

I love happy endings...
