Land cruiser 70 bcm location (1 Viewer)

[nico3dd]

Hello, Im desesperately trying to locate the bcm for a 2012 70 series. And Giving up. Thinking there is no such thing in this vehicle. Am I right?
Couldn't find anything related in the web either

Hello,

There is no BCM in a 2012 70 Series truck.

ABS, traction control and other stuff started on 2013 model year if I remember correctly.

If your truck has a 1HZ engine, there is no ECU either.

It has 1GR engine. I'm thinking maybe the BCM controls the instrument cluster? . But I'm not sure as it's the same cluster since 2010.

Hello,

There have been changes in the instrument panel since 2010. Most of them started in 2013.

The instrument panel is rather simple by modern standards.

There is an ECU for the engine in the dash panel and that is about it.

Yeah I think it just runs with +12v. No BCM to convert it to +6v as modern and more complex cars

Hello,

Yes, it is 12 volts. And yes, it is not as complex as modern cars. A number of pickup sensors, some of them electronic, send data to the circuits in the instrument panel, which convert the data to gauge/odometer readings. There is an EPROM in the odometer module if I remember correctly. The panel communicates with the engine and 4WD ECUs, as well as the fuse and relay boxes. There is an OBD port close to the steering wheel for diagnosing the engine ECU.

No BCM there, but separate systems that can be disassembled, repaired and reassembled one at a time.

BCM components such as relays and certain fuses are in separate locations, namely the relay box and the fuse box. Toyota moved the latter to the engine bay after 2010 if I remember correctly.

Thank you very much for you input, as I found it very very useful.

You see, I'm upgrading my 2006 lc71 running the mighty 1fz-fe, with the 2012 dashboard. And it fits 90% to my old body.
I have pinned the light and wiper levers already, but I was told the 2012 had a BCM therefore will not be able to use the instrument cluster without it. But with this new info I'll try to pin the cables to see if it works out.
BTW, wouldnt you have an instrument cluster wiring diagram laying around by any chance?
