https://www.techauthority.com/en-us/products/?year=2008&model=548not sure which book is best,ask jeepthe correct book walks you through all steps. seems its abs (distances calce errors)or the sensor is bad or dirty or loose or damagedlooking at it can do WONDerSmight even be bad brakes therewhy not get the brakes checked by a real shopASE shops ruleABS NEEDs good brakes FIRST.1 case in point a grabbing brake, or other odd behaviour)ever google search seems notone guy had bad wheel bearinga good shop (why not use one) would check that corner 100% bearing, shocks, sensor, brakesand tie rods, (all means, ALL)if tire hops moving and braking abs will be upset. ABS is not genius level yet.all it knows is the sensors read odd.!!!!and even compares them to others and true veh.speedwhy not get a real mech, in the loopan ASE SHOP.it can also be network errors on the can buss network, that means using a REAL scan tool.or you miss ALL THAT. (id bet no net error here)the ABS sees odd readings right side sensor RF and RRtry to think like a dumbb computer (no joke)if it sees one sensor , different and not braking and not turningor one locks up, or varies. oddly braking.oddly is he key word, or IT tries to prevent a tire on right side from skidding but cant... (dah bad pads ,etc)warped rotors??????see how that works??bad brakesbad sensors (means wires there)skipping tireswobbling tires,rotors, bearing SHOT.dead shocks (hopping like a bunny)bad belongs.sticky pads, burned up. or ???? not same match to others (do no mix brands up)worn pads to metal back platesoverheated brakes wobbing rotors.(loose suspension parts right side)do i need go gone on naming everything a spinning braking tire can do,wrong,, why? take a class on brakes then ABS,???check for bad wires.check brakes.check bearings.even loose lug nuts, really.wrong size tirebad tire, treads not same 4 corners.or get car serviced ,that ASE guy knows what to do.when abs fails , try to not think ABSfirst (sure, wires)try to think ABS saved my life by telling mebraking is bad before he human noticed it.!!!it does this very well, this early warningbut is dumbb... it can't know the wheel bearing is atdangerous state of being../ just odd data, it sees.(funny "odd" tone wheel, data from the sensors) see choppy data... confusing to the non AI brainit's not 2050 year.?i did not list all possible points of failureits too huge.(ok pinched brake line)get car serviced, why not?or caliper slider pins sticking.... oops...
