ABS light and 4 hi/low flikering

Had a bad wheel speed sensor but lights are
still on after replacing and reset codes w/ a snap-on
scanner any idea's?

 

yes, about 5-6kohm R-side & L-side. shook wires but was solid reading- the left rear sensor was out and replaced it- was in the mega ohm range. Snap on scanner said it was good now but lights were still flickering-

 

that was 5-6k ohm on the wires back to the ecu

 

its a friends who just bought from a dealership as is

 

the vehicle has a add on air bag system. so at first I thought it would be the wiring... but looks and measures ok

 

I pulled the rear two and they were clean, Ill have to check the fronts next time I see the vehicle the rear abs teeth were clean

 

hit all the fuses w/ a test light had a 30amp blown. replaced it and you can hear the frequency at the brakes when controller or pedal is pressed. He said on the way home they were still doing it. also said the trailer did not seem to slow him down so, need to check next time I see it.

 

Ill know next time I see the truck and trailer combo

 

was only 1 of 4 units working- I hate scotch locks- I prefer the molecular connection solder!! re did the connections and all is good now with the lights on the dash. Guess its like the Q7's information display ,if something is wrong with the trailer it shows it. but no display on the Tundra- Thanks but mainly it was trusting a guy at his words.... people say things to get their junk sold and no, you didn't check the trailer brakes out- but he did lube the axels which need adjustment too
