Undo what you did.































What exactly is "some wiring"?































Without knowing exactly what you did it's impossible to diagnose.

"I was doing some wiring " - There's your problem right there, are you a qualified auto electrician?















Don't go messing about with the complicated electrical system of a modern car, you'll regret it.















Take it to someone that knows what they're doing before you f*** it up to the point where the car's scrap, I've seen it happen when amateurs start screwing around.

Hi you simply can't mess with this beast especially when it comes to wiring the body module needs to be advised when things are added or removed as does the engine management system also this is all on the CANN and buss systems which is a network around the car which controls it even when you are tucked up in bed at night. microprocessors by the hundred is some makes and models.















that is what produced the modern car since 1980.

One thing you should not have done is to play around with the wiring,as well as causing the problems described it may be a fire risk.The ECU unit on your car has sensed a problem and acted accordingly.Different strength of wires are fitted in Cars and these must not be over ridden.From memory having run this model,certain systems remain active when the vehicle is switched off,this would lead to a flat battery,and better to consult a Lexus dealer who will help you.

There are many, many things that could have gone wrong from blowing a simple fuse to frying an ECU (Electronic Control Unit), the ECU's on the CAN are by "nature"/design pretty robust to "DIYers" but not fool proof.















From what I can see in the schematic (early 2000, 200 series), all your symptoms come (are controlled) from the same ECU, some of the simplest faults that I can think of would be to look for a blown fuse, a connector that has become loose or disconnected, or a data cable has been used as a V+ or Ground by accident.















As I said at the beginning there could be many causes and has been suggested by:















203 ?undo what you did?, Evelyn also has a good suggestion or two as always and so does Realdolby have good advice















@ Bears face















What is a CANN or buss for that fact?















Do you mean the CAN, Controlled (or Controller) Area Network and do you mean bus as from the Latin omnibus, meaning "for all", as used in electrical (bus bar) and Computers CPU bus, IDE bus and PCI bus ?
