Hi Collin. I will be bidding on these anyway, but can you tell me if there is a wiring diagram section in these? Also have you any parts other than those advertised. I am looking for the radar distance control  unit  88210-30080, and the steering wheel switch for the distance control. Thanks.

John.

I have the 5 volume set of these . The CAN Bus section is there(V5) but I dont see a separate wiring diagram section .

Thanks Nick. Does it show the wiring for this?

No .Thats not how these manuals work . They show a system diagram and then proceed to tell you how to fault find . Quite comprehensive . but a traditional wiring pin out diagram No. they take each system check and go through the diagnostic checks in turn . Its quite a complicated system depending on many peramaters . Its the first time Ive looked through them in 10 years . I sold my GS450h in 2011 and moved away from Lexus as they introduced that horrid "BATMAN" styling in 2012 with the "GAPING MOUTH "I think the prat who designed them ten went to Honda Civic for their boy racer styling . !!😈

Again Nick thanks for your reply.
I am in the process of retro fitting radar distance control to my GS450H. The distance control ECU is under the dash is pre- wired "and now fitted" as is the distance set switch wiring in the steering wheel, but the switch is not fitted. The radar distance unit in front of the rads does not appear to be pre-wired. I know it only has five wires going to it two of which will be the 12 volt supply leaving only three wires to connect to the body ECU in the engine compartment by the side of the fuse box. Two of these wires are probably CAN bus wires, and the third possibly an enable?
I am a retired electronics engineer so connecting this sort of thing does not phase me, but a pin to pin diagram for this unit would be very helpful. I have the setup procedure for aligning the radar unit, and the enabling method for the actual ECU. I also have Techstream to follow any fault codes.

Retired Aircraft Engineer here who then Started my Electronic Repair Business for 20 odd years. i too have mongoose and TS.There may be a volume on actual wiring diagrams but not in these volumes . There is however a comprehensive  Diagnostic and Schematics in VOL 4.I dont suppose they expect someone to try and retrofit this as it was factory only fit . I wish you luck . The schematics will allow you to figure it out if you are an "ace of the base"

I will keep you informed as to how I get on with this little project, and of course if I am successful I will do a write up on the forum  on how to.
Thanks again for your incite to the manuals, and as Collin has volume 4 it may give me useful information.

John.

Thanks for the reply. I will bid on the books anyway. I hope the reserve is not to high.

Hi,

I attach here the circuit diagram for the radar distance control of the cruise control.

I hope it can be useful.

Thanks Chris that's just what I was looking for.
I have bought for £20 and fitted the distance control ECU (L13) to the existing wiring, and mounting bracket under the dash. I have yet to source a millimeter radar distance sensor (B8) to fit at the front of the car. The wires for this do not seem to be ready installed "I have to look deeper", but there are only 5 in total. A ground wire, a signal ground to the hybrid ECU (A55), an ignition Battery feed, and two more that go to the distance ECU (L13).
I know I will also need the Lexus logo badge for radar for the front grill, and fit a micro switch to the steering wheel to set the distance. The single wire needed for this is already there plus ground.

That complete wiring diagram was available on line from Russia until early this year when it was removed. I would have copied it to a CD had I known it was going to vanish.

John.

Hi John,

You are welcome. I hope you will be able to find everything you need and I have no doubt you will get it to work.

Now I'm interested! I've been thinking the same but had no time yet to start investigating the topic... I hope you will be posting your progress for us 😉

And thanx Chris for the wiring diagram!

If I manage to get it up, and running I will post the details. I have just bought a radar unit for the front of the car from Ebay. I made a cheeky offer of £45, and the seller accepted it.

I have the full instructions for aligning the radar unit, but may try using a lazer system I have to align it for both height, and centre axis. This will then not need an empty large carpark to align the radar unit.

If anyone can help I need to know the location of wiring connector plug, and sockets BA2, and LA2. These plug, and sockets join different sections of the wiring loom.

John.

 Nice one - will be interesting to watch this progress for sure. Have you also procured the specific ACC front grille?

My car has ACC so happy to take photos/video of what you need, if that helps.

I think you should consider starting a build thread for this, John  🙂👍
