Electrical issues

[albe]

Hi, where can I find electrical wire diagram of lc200 2010 4.5 diesel? I have a lot of oxidation into the kick panel connector driver end passenger side end I need to try to solve some electrical problem. Can I bypass the damaged wire? I have problem of the button of a/c, radio, front end rear windscreen defrost

Yes, you can bypass the connector - it is the cheaper/easier fix.
But make sure you first find the source of water intrusion and fix it. Then disconnect and dry well all connectors.
The diagrams are in the manual but I don't know where you can get the manual for non-Us market cruisers.

Ok thank you.. I found end fixed the water intrusion months ago, clean end dry a lot of time all the connector, probably some wire are damaged. I have asked because a meccanical here told me I cannot bypass the connector because is can-bus sistem

A plain wire is a wire, no matter what kind of signal you send through it.

Agreed. Only a couple of the wires out of the ~dozen or so will be canbus, and if you want to be really OCD you can twist those wires for the bypass like they usually are for the rest of the vehicle. But that short distance shouldn't matter.

How I know: I swapped a GM powertrain into an older landcruiser and elected to use the GM Body Control Module for reverse lights, cruise control, tap shift, and other functions. This meant wiring up my own canbus extension to add it to the engine/transmission daisychain.

Thank you

The problem is I don’t where is the harness for the radio botton, because someone doesn’t work ( audio-climate-navi-front end back windscreen defrost)

You'll need to have someone go through the connectors pin by pin to determine which ones need addressing. These systems are too complex to tell definitively which circuits are bad based only on symptoms and wiring diagrams.

Plus that process may find other pins that aren't bad yet but will be soon. And absolutely figure out why they are corroding and stop whatever leak is causing it.

Yes i found water intrusion mounts ago.. end I have stopped it.I have try to ask you if know which harness connect navi or radio, left or right side or what modul.. I have tried today I will leave the car to the electrician, I hope he can find something

Thank youu
