Hello, I bought a 1999 Lexus LS400 1 and a haft year ago. It was very reliable and I never had a problem with it. I got a problem with the wiper control. I replaced the MPX body control to fix the problem. After that my remote key stop working. I ignored the problem and keep using the car. Two days ago, a technician reprogram my remote key and make it work again. (doors, trunk, locks, all worked perfectly). I started my car and was very happy to drive home. In the evening, when I got in the car, the car cranked but didn't start. Is there any chance that the immobiliser system is causing problem? When I put the key in, the security light turns off as usual. I checked all relays and the battery and all work well. Except for the fuel pump relay that not powered when my key is in postion On. But I think this is normal. I suspect that immobiliser system or my ECM is causing problem because my car worked very well before my remote key is reprogammed. I don't know what to do now. I live in Vietnam and it's hard to find a mechanic to fix my LS400. I intend to replace a new ECM + key and I found this link on ebay: http://www.ebay.com/itm/191737878103 However, I also found that there are variuos part number of the ECM for the North American market: I haven't check what is the part number of my ECM .IKindly let me know whether the ECM part number 89661-50531 can replace the ECM part number 89661-50502 or not? Many thanks!

My unit works just fine. It's just the display screen is a little dark and difficult to see in day and night. I just want to change the screen itselft (not the whole unit). Maybe the screen from the gs400 will fit? My ls400 has only 91k miles on it and it still look beautiful: : Sorry for my bad english. I'm from Vietnam :) Another question : when you swap to the standard radio and HVAC control, will it fit directly? Thank you!
