ABS light on after caliper swap and car wont turn off

kenney255 · 02-23-2019, 06:28 PM

I decided to swap my base model calipers out for the akebonos and stainless brake lines. Everything went fine on the install so so i called it a night. The next day when i went out to bleed the brakes and after watching a youtube video the guy suggested disconnectiong the ABS module by the brake resivoir.
Proceeded to try a new vacume pump i just bought which worked like **** so i got my girlfriend to come out and pump the air out by pumping the brakes. After i was happy that the aair was bleed i plugged in the ABS module and started the car (car still on jacks no wheels on ). Car started no problem but i noticed the ABS light and traction light was on , Tried to turn the car off and it wouldnt turn off. I just dropped the clutch in first gear and stalled it to turn it off.

Anyone ever run into this problem? i havent sat the car down on tires yet and drove or tested out the brakes to see if their might be air in the lines.

I should also mentioned i just installed UpRev this summer and i should run the codes but im not home this week and the problems eating me up..... my babys sick lol . I also read if the battery isnt fully charged sometimes the car might not turn off? i only drive the car in the summer so the battery might be low.

Thanks

I've had this issue happen a couple of times to me now. For me it's always been when I'm out autoxing and $hit gets hot.

For me it seems related to the wheel speed sensor getting too hot or getting crap on it. Both times, I let the car sit for a while to cool down and it went back to normal.

Also if you need to turn the car off when this happens just hold the button down and after a few seconds it will eventually turn off.

Im might be a possibility that i got brake fluid on the speed sensor now that you bring it up

I think it's only one bolt that holds the sensor in place. Just remove it, spray it with some brake clean, wipe it off, and re-install it. It's a magnetic pickup that read a tone ring so there isn't much to it.

You might also need to take the car for a quick drive around the block to get the warning light to go away but I can't say that for sure.
