I have a 2004 LX470 , and the stepper motors in the cluster have failed , specifically on the fuel and voltage gauges. I ended up finding an instrument cluster from a 2005 LX470 with an almost identical spec to mine (no night-view, etc. ) and popped it in. The "new" cluster works great - all he gauges work perfectly, it's so nice to have a working fuel gauge again. The problem is that many of the malfunction lamps are now lit ( maintenance , abs, AT Oil temp, etc) I used my Techstream to scan for any codes, and there are none. I opened up the back panel of the 2 clusters, and compared part numbers on all the chips, and they are nearly identical. only one of the chips had a slightly different part number. I also found one little chip that can be easily swapped over (see pic) , I tried the new cluster even after swapping this little chip, same problem. Anyone have any ideas of why this could be happening ? I doubt there is anything i can do, but I thought I would ask
