Hey I am having the same issue but another issue came up with my tranny not going into reverse..So I unplugged the tranny controller under the drivers seat and then the FOB started working where I could lock the doors remotely..I did not have a problem unlocking just locking...I know now that the BCU, ECM and the EAT are on a network called CAN..Just something to look into as one of those controllers may need to be replaced..Try it for yourself..I am currently trying to find out as much info from the RAVE workshop manual..Good luck

 

Like i said before your bcu is more than likely your problem.

 

Radio and interior lights are not working either. Ultra gauge isn't working. Is this all off of the bcu?

 

It is possible,

 

So I read into the rave and the BCU controls the windows and some other things that are just fine. I checked the BCU fuse and it is good. The radio is not working the AC defaulted to Celsius temperatures and my key fob is still not working. My OBD2 sensor is not working bc my ultragauge wont power up anymore. I have no idea where else to go or look. Any help would be appreciated.

 

I am an idiot!! It took me a while and lots of fuses to check but it turned out to be a fuse. IF this happens to you check every fuse to every component. For me it was approx 5-6 fuses and when the first 4 were good I assumed worse. 10 Bucks later I am good to go.
