2006 Ford F150 5.4 Brake light & ABS Light on ??

Unread post by dynamitejake96 » Wed Dec 03, 2014 12:25 pm

2006 Ford F150 5.4
My parking brake light came on, and a few weeks later my ABS light came on. Now both lights are on, brakes seem to be working fine.
Brake fluid levels are fine.
Suggestions ?
Thanks,
Dynamitejake96

you should have the ABS scanned for codes to see what the computer is turning the light on for.

Maybe the fluid sensor isn't working correctly. If the master gets low and you refill it sometimes the float gets stuck at the bottom.

make sure the park brake switch is working correctly.

Thanks,
I had it scanned yesterday.
They told me I need a new Electronic Control Unit [ 800.00 ]
Before they can even tell what is wrong with the ABS ?
Then they said they would be able to see what is causing the Parking Brake and The ABS light to be on ?
Sound Correct ???
Thanks....

did they say they couldn't communicate with the ABS unit? is that why they say it needs to be replaced? If that is the case, did they verify the powers and grounds were all good before they condemned the unit?

Yes, they said they could not communicate with ABS.
Yes, that is why they said I needed a new Electronic Control Unit.
Not sure, will check to make sure powers and grounds are all good.
Thanks for your INFO !!

check the fuses in the central junction box by the right side A pillar.

fuse #2 20A light green wire to the brake switch then to pin #6 (hot all the time)
fuse 112 40A Yellow and light green wire wire to pin #13 (hot all the time)
fuse 103 20A orange and yellow wire to pin #14 (hot all the time)
fuse #14 10A light blue and pink wire to pin #8 (hot with key on)
fuse 15 5A red and yellow wire to the traction switch (hot with key on)

check for good grounds from pins #12 (black wire) and #15 (light green and yellow) at the abs module.

if all the fuses are good and there is power to those pins and the grounds are good grounds at the #12 and #15, then I would think that the abs module might be bad.
