PSM/brake fluid lights during DE

[Toby]

I have been having issues with my brake fluid light since I got my car 2 years ago. It lights up during my AX and DE runs, particularly when I engage ABS trail braking into a corner. I understand that it's due to fluid sloshing around the reservoir. The pedals have always felt fine, so I tend to ignore it. (The light always turns off when I cycle the ignition.)

In the past 2-3 events, in addition to the brake fluid light, the "PSM off" fault also comes on. The car will continue to run without problem, and the both lights will extinguish when I shut off the car after my session.

(I remember the "PSM off" fault also (first) came on when I spin the rears a lot trying to get up an icy slope.)

What's going on? Is it just PSM getting confused thinking it need to engage with a low brake fluid level, so it throws the code? Is it something more serious?

I have a 2001S with PSM. I use Toyo RA-1's and Pagid Yellows on track.

Thanks,

Toby

Hi Toby,

this is a very late response to your question.

I had the same problem as you and replacing the lid of the brake fluid reservoir did the trick for me...
