Hi all, We had a 2019 RX stolen recently via the wheel arch CAN bus method in what appeared a professional / targeted theft. Before committing to buying a replacement (and risking a repeat theft) I am trying to get comfortable that Ghost 2 (which I would have installed) cannot be somehow bypassed. The main thing I’ve not been able to determine is whether the actual hardware (the chip wired in) can be removed if thieves know what they are looking for. Thinking in particular about RXs. Speaking with a couple of installers I’ve not got much clarity. Can anyone advise on this? If any security concerns any direct messages also would be very welcome. Many thanks, SA

I'm trying to start a friend's car, which has stood for 3 years with a flat battery, with a view to possibly buying it and saving it from being scrapped. I have put a fresh battery in, but it won't even try to fire up after cranking for several seconds. Tellingly perhaps, there is no smell of fuel, which could be expected after sustained cranking. I am suspecting the immobiliser, which seems to be the most likely cause following the fitting of a new battery, according my research on the internet. The central locking and alarm work just fine. I spoke to a very helpful technician at the main dealer here in Milton Keynes, who said the immobiliser might need resetting, and to leave the ignition turned on for 10 minutes (although on the internet several people suggest 6) after connecting the battery, but unfortunately that didn't work. I obviously need to check for a spark, and see if the plugs are wet after cranking, just to be sure I'm not barking up the wrong tree. If I could draw on the experience of others, I have several questions: Is there another resetting procedure I could try? I understand the security systems (possibly Scorpion) were dealer fitted in this country. It seems that pins 2 and 3 on the fuel pump relay (FPR) should receive a current with the ignition on. Pin 2 supplies the actuator and pin 3 supplies the pump, via pin 4, when the switch is closed. Is that correct? I found the attached diagram which helped. Does the immobiliser cut the power supply to the FPR, or the pump, or something else? Could I run a test wire from the battery + terminal to pin 4 on the FPR socket, which according to my logic should tell me if the pump is working? Does anyone know if Lexus tended to fit the immobiliser control unit in a consistent location, and if so, where? My assumption would be on the interior side of the front bulkhead, but I am reluctant to start dismantling underneath the dashboard just yet. Once the control unit is found, does anyone know which wires are for the immobiliser unit? A wiring diagram would be very helpful. I am reluctant to engage an electrician just yet, in case the solution is reasonably straightforward, so any guidance or advice would be much appreciated. Lexus LS400 fuel pump relay circuit.odt

Hi guys, first time posting here on this forum looking for help. I currently have a 2000 Lexus is200 as my weekend (fun car) while my daily was in getting repaired I was driving the Lexus as a daily but when my main car came back I parked the Lexus up starting it every so often. Then when I went to start it one day it just kept turning and fuelling but would not spark. I had to charge the battery also. I checked power to cool packs and they all have power going to them. I've checked all fuses and nothing seems at fault there. While I was driving it as a daily the plastic part of my key, which is the only one I have for it, split. I glued it back together but I've a funny feeling this is the issue that the chip isn't sending out a signal. When I put the key in the ignition the red dot security light is not lighting up! Does anyone have any ideas or people who could sort this for me ? I'm in the Meath area of ireland. Much apprecited.

Hi their, I'm having trouble with my immobiliser not deactivating and because I don't have the master key I cannot reprogram the ecu. Anyway I've found a new ecu and lockset only problem is my ecu part number is 89661 53200 and them replacement is 89661 53031. Someone told me it would work aslong as I change everything it would work.........is this true??

Hi, My Lexus was running fine last night but when I started it this afternoon, the engine starts and then cuts out after a couple of seconds. A friend of mine hooked it up to his OBD reader and it came up with B2799 engine immobiliser system malfunction. I obviously cant drive the car and the nearest dealership to me is an hour away. I was wondering if anyone has had the same problem or could suggest something? Lexus 220D 2006
