history? how long did you own it before it blew fuses, ? Hmmmmm
well the very thing that sets the ABS errors , lost power so I can not communicate to you is why. (nor as it died on the fly)
there is no need to presume, we use the service manual schematics on
That fuse, not clearly told.
Code readers are JUNK, we use real scan tools that also cover ABS GM> sorry wrong tools make the job 10x more hard.
under hood fuse 31, ABA MOTOR, IS 60 AMPS SO IS NOT THAT FUSE. aka EBCM fuse so is not this on but is 13
OK I found it,
Fuse 13, hood box ABS.
F1 3goes to pin 16 of
EBCM
the EBCM run the BPMV modulator valve. (bingo)
4 wheel sensors
EBCM sends +5v to 2 other sensors steering and lat. accel.
the sensors shorting would put the 5vdc regulators in overload shut down and set DTC. .
I think bingo line above is bad,
EBCM is it, and, the BPMV I bet runs off the 60amp fuse.
the wheel sensors are very tiny mag coil sensors that use no power feed at all (just like 2wire CKP crank sensors) they are
not hall WSS sensors 3 wire with 5vdc, so is
not WSS sensors shorted. IMO
tech: WSS:
WSS produces a small AC signal, tiny. and has special ZCD detector amps in the EBCM, flea power stuff.
My guess, based on year, EBCM caps in side it shorted, (cap plague year here) wiki covers this Plague.
wheel speed sensors:(SM tests)
wss spec. sensor unplugged
Test for 850-1350?ohms between the signal terminal A and the low reference signal terminal B.
less is bad and a coil is shorted, inside WSS
infinity is open Wss coil (they are only faraday coils)
the SIGNAL from them
100mV (0.1vdc AC ,) using scope spinning wheel./tire. by hand. a sine wave signal.. not square like HALLS do.
.
I am really sure WSS are not blowing fuses.
EBCM is bad. <<< caps in slide sorted. even exploded inside.
or leaking boric acid from inside caps. or bulging.
