Hi I've the same problem with the radio amp 86280-0w040. The fail came totally true when i put back the fuse (30 amp). The amp burned... smoke blows out. The final result is shown on the attached pictures. The MOSFET 76443p was burn and the nearest component "capacitor" was damaged? No code markings??? Who knows what is this component? I ask you do not put back the FUSE again. You can try to solder the cold soldered joint of the q492 again.. and perhaps works. I've bought the new mosfets HUF76443p3 but now I've this other problem how to know unknown component without markings. Who knows where to find the printed circuit board of the 86280-0w041? I do not really know what is the little silver "box" 3.2 mm x 1.6 mm? Antero

Hi, pls find video interface: http://www.navtool.com/lexusls430460navigationvideointerface.aspx Greetings Anlex

Thank you for your replay. The clues are hanging on BEAN, Body Electricity Area Net. In chart there is only one wire? It is said in diagnostic papers that the code B2775 comes from Theft Deterrent ECU via Multiplex ECU (Gateway ECU) to Steering Lock ECU (w smart key). Diagnostic procedure asks to check all keys and I have checked, they are OK with new batteries including smart key. The Diagnostic of the inspection procedure result is: “All keys are OK so the system is normal but it is suspected that verification was failed in the past”. What means “in the past”? Is the Transponder Key Amplifier read the code of car key wrong in earlier session? Could the coil be damaged or low level working (Volvo has been same symptom and it is fixed by new coil)? How to check an unserviceable coil? May be the fault is in wire harness or in BEAN? Antero PS Immobizer stall engine soon after starting "twice a day". Engine starts when doors are shut/opened outside many times... the roblem is soon real...

I have checked the relay and resistor of the fuel pump. The fuel pump runs when cranking and some seconds afterwards, too. So fuel pump should be ruled out. Dealers code reader result: B2775! If we believe the DTC reading result B2775 (giving by ECU?) which says “Interior verification abnormal to theft deterrent ECU”. Inspection: All keys start the engine OK! The malfunction manual of the diagnostics says: The system is normal but it is suspected that verification was failed in the past? Where to start checking? I have emptied the battery twice by cranking and after 30 - 120 minutes engine started nicely (once helped by outside battery). A new feature: Yesterday LS stall two separate times but at these time I didn’t empty the battery, instead of it I jumped out of the car opened and shut the hood of the engine then I locked doors by the key, opened and locked and of course some rain dance steps... I jumped into car …. and engine started well! Conclusion: The Manual of Diagnostics was right-on: “the problem was failed in the past”? Anyway a symptom is still somewhere! Where is the real problem to fix out? Yours Antero

What is problem if engine starts but stall in 2-3 seconds. When cranked many times it only gives some promises to start. A symptom has realized ones per week during last two months. Both keys the main and the sub key work fine and also the smart key system! Note, the engine starts after half or couple hours without any repairing or harm! The DTC of Malfunction is read by Toyota tester, it gives the B2775 . What is wrong where to start repairing - voltage drop? - grounding conductors? - MPX? - Theft Deterrent or S17 steering Lock ECU or.. engine ECU? - Door locks? - Is B2775 only a reflection of some other symptom? - etc? Please could you help me find out what to do with this malfunction. Lexus dealer says it to be taken several hours or many days to find out to solve a multi difficult problem . Yours Antero
