ABS light came on, what could it be? Also i could barely pull on my brothers 350Z on the highway
 

I have an x chip and no mufflers. The 350Z is bone stock.

350Z's have a very strong fourth gear. STFA for ABS light, check for codes.

i did search, seems everyone has that and the brake light come on the same time
 

i only have the abs light so i thought it might be different. I'll have to take it tomorrow to try to get a code.

Check the brake fluid level, it might be low or just sloshing around

wheel sensor maybe, but dunno why you're not whoopin the Z

I have had the same problem too, it is neither the brake fluid level
 

it is because the ABS control module is failing, I had to replace mine on my S4.

well the light went away...and the brake fluid level IS low
 

I'll have to top it off, i didnt even think about checking that.

Fuse?
 

My battery drained once after sitting for a few days, and upon finally getting it to crank the ABS light and red "Brake" warning lights were on. First thing I did was replace the fuse, which resolved it.
