Abs And Trc Off Flashing

[Rez89]

Hello there, I have a Lexus is200 2004 plate, it's a limited edition model..

As title says I'm having that problem. Took it to a mechanic and had diagnostic plugged it an came up with fault abs modulator and break peddle switch, changed both parts and still have the problem. The main issue I have is that when I brake non of my brake lights come on and this is really bothering me. I don't know what to do now, auto electrician maybe?? Any help and advice will be appreciated. Thanks

You are certainly going to need some electrical experience and be able to use a digital multimeter and read wiring diagrams to be able to sort the problem yourself.

An autoelectrician would probably be your next step.

If some one could post up the wiring diagram I would be happy to take a look and try and help.

I wouldn't mind giving it a go myself as I have spoken to an electrician and he goes first time he's heard of a problem like this on a Lexus.. I don't know if this is related too, I've changed the fuses for my cig lighter to work and now the heated seats don't work, so what I done was changed all of the blue 15a fuses and then the seats or the cig don't work. Just had a play round now as I need the cig lighter for a journey tomorrown an chaned the fuses around an it seems to be working now.. I've owned 2 other Lexus before this one and never had any problems.. Thanks for your reply Steve.

IMO for any strange electrical problem on the IS.....the easy first check is to ascertain if water is getting into the fuse boxes in the footwell, it's probably not your problem.....but a screen leak (or in my case a miniature leak through a bulkhead grommet) can cause untold gremlins in the electrics. I had some water poured over the ends of the screen, and after a while.. drips appeared.
