2wd or 4wd truck NO VIN posted so not sure what this is at all
r
so never ever see this one car work right ?
both ABS left and right rear?
double compared to what???????????????
learn how,? using what methods.
both rear wheels in the air rears
speedo speed,?
A/t box?
or the up to 3 transmission VSS sensors speeds?
some cars PCM use ABS for road speed.
(it averages all 4 to get true speed) my Jeep does.
no DTS posted at all ,must we guess them>?
wrong ABS parts used? axle swaps and now ABS sensor and tone wheels are dead wrong/
nobody can know history of car (service)
look at any ABS tone wheel ring
it has a large number of teeth and 1 full turn
produces a huge number of pulses. and the PCm counts them down by the teeth count.
to 1 turn, if wrong parts here it will fail
sellers for rings show 54 teeth, to count down
is car 4wd or 2wd, that too can use different parts here.
or scan tool not set to 2wd or 4wd mode.? or is lame.
when did car run right before now (your eyes)
rear or front hub tone ring. the axle hub can rust and it might slip,. I hear they do.
54t
the PCm to do RPM here it must scale many thing for MPH. (true speed)
this ring divided by 54 is one turn. and by tire diameter to computer speed.(turns per mile)
then gear axle ratio must be used to computer VSS tail shaft speed say 3:1, the tranny spins 3 times faster. than the axle (easy no?)
see?
so if doing comparisons of all these sensors one must know all those facts. or will be wrong./
post DTC to get better help
and if all actual brake are ok all disks, and calipers
ABS can not use defective brakes, a tad weak sure.
not with warped rotors or omg cracked rotors
or wrong wheel size or mixed up wrong tire sizes.
or caliper slider pins are siezed
or caliper pistons seized or more.
