I just ran into a weird problem where the car would start and run normally, but many of the dash warning lights were on, the AC wouldn't run, the rear brake lights wouldn't work, the radio wouldn't work. etc. Couldn't shift out of gear. I checked every fuse there was, every relay there was, and still same problem. UNTIL I found that the fused positive terminal link had a crack in one side of the trace. I replaced the positive terminal fuse link for 13.95 from Toyota dealer and wallah... Problem Solved.

 

I'm have the same issues with my 2011 xD and have had it at the dealer to diagnose. They finally want to replace the ECU for $1200 but I opted to get a remanufactured ECU. After replacing the ECU it is still doing the same thing. Just wondering if you can provide any info on the location of fuseable link that you replaced.
Thanks
