    Stiff Shifter on a 2010 LX570

    Neutral safety switch is something other toyota forums have mentioned might cure this. You can look into Tundra forums as they have similar issues.

    My immobilizer fix

    Just got the notification for this thread. I got the power straight from the battery with an inline fuse.

    My immobilizer fix

    So here's something to ease these diagram and wirings: Going by the 2 terminals A and B of the fuse, and 4 terminals of the relay as per the attached diagram (fusebox1), this is what they correspond to: A: Gets constant power , +12V : connect this to new relay pin 87 B: Gets constant power but...

    My immobilizer fix

    Didn you try to jump a canle connection directly from the battery. Does that still work ?

    I figured I'd someone else stumbles upon other posts they would get the solution too. Thanks again. You're awesome !

    My immobilizer fix

    thanks, perhaps for the clarification of others who read this thread, is it correct to point out that the E terminal where the original relay was connected and is left out in the pictures here for the solution (ofcourse corrected in your updated kit); E terminal is connected to the BATT node of...

    My immobilizer fix

    thanks much, what is a good place to tap into the constant 12V, what about the to your kit that's feeding the relay, can we simply tap into the same source and feed terminal E. In essense, I assume what we are doing is shorting terminals B and E with a fuse in between, or getting a constant feed...

    My immobilizer fix

    Thanks, thanks. as for the P1600 code, someone mentioned that you sent them an update wire etc to fix it. i'm guessing based upon the link you posted for the error code that somehow you have supplied node E which is left blank with a constant 12v source ? if so , where did you tap into for the...

    My immobilizer fix

    adding another diagram, showing that the BATT terminal of the ECM requires 12V as well. given in the bypass harness we are leaving terminal E blank, that leaves BATT of ECU needing the 12V that it doesn't hence throwing a P1600 code for me and a few others. Waiting for someone who used the...

    My immobilizer fix

    Hi Bob, did you ever figure out the error you used to get when you were powering the bypass kit straight from the battery ? i'm getting the same error and like you said, the error goes away when i put the original relay back in. interesting thing is that i don't put in the EFI fuse back in...

    My immobilizer fix

    DrJMan, did you leave the terminal E blank ? if so did you ever get the P1600 code by leaving it blank or did you feed it power ? thanks.

    fix for immobilizer issue?

    I have the same scenario with the kit throwing the P1600 code. what is the second part of the kit you received ? is it getting power to terminal E from a different source ? if so where is it getting the power from if you would kindly share. thanks much ! :)

    My immobilizer fix

    posting a picture of how power should be applied to factory relay. based upon the kit by medtro, your kit terminal E left out of your kit, as per the ECM diagram I'm attaching that needs a constant battery power which if it's not there is likely throwing the P1600 code for some. I still...

    My immobilizer fix

    Hi Medro, have a question, because using this solution is is giving me a P1600 error code I'm trying to trouble shoot it. Do you have the factory wiring diagram for the EFI relay which I'm guessing you used to figure out what the 4 terminals C,D,E, and F are to connect to with your kit. Also...

    100 Series Fuel pump relay location

    Thanks much for sharing this diagram, I'm trying to do a bit of troubleshooting and need to know what the 4 terminals of the EFI relay are connected to. I know terminal 1 is what we are trying to get 12V, need to know the other 3. : 1 - 12V ultimately needed once everything is working. 2 - 3 -...

    My immobilizer fix

    Hi Kevin, I have a question, my fused locaiton B as per the diagram attached is not getting any current neither is location A. so i completely needed to bypass my fuse holder location for the EFI fuse. Do you by any chance have the schematic/diagram for the EFI fuse that you can share. I'm...
