ABS Brake Serv 4wd lights

Weird occurrance. 2010 4WD 26K miles

The ABS and BRAKE lights flashed on/off intermittently, and I would hear the chime

Then they came on all the time along with the SERV 4WD light

Then after a couple of drive cycles they went off, and havent come back on

Whats up?

Thx

Not sure...

Stock? Deleted? Any mods?

Could be just a chance occurrence.

Mine did the same thing..... It irritated the heck out of me...

you might want to pay attention to when it does it....

it will start to occur more often...

with mine, my brake lights were staying on...

After they stayed on for a while, i would get the warning lights....

dealer couldn't figure it out for the longest time... no codes...

turns out that the brake pedal wasnt returning completely causing the brake lights to stay on.

the only way i noticed it was i got out of the truck to unlock a gate at night and noticed that my brake lights stayed on... from there i was able to narrow it down to when it happened....

ended up replacing hydrobooster on the brakes...
