Abs Failed After Cv Joint Change.. Any Clues..

[Warren94GT]

Hiya,

Just after I purchased my lovely 1994 Celica GT it started knocking from the front left wheel.. (read that as it nearly broke down on the way home from the garage I got it from) I recognised this as CV joint noise from my old Scirocco days.. Anyway my Mechanic replaced the CV and as a precaution BOTH the boots plus at the same time stuck new front pads on. When I collected the car the ABS light was on and has remained on since. ABS seems to have failed - brakes are vibrating under medium heavy breaking. Has this sort of thing happened to anybody else. I asked him if he disconnected anything and he says no.. He has mentioned that it might just need a re-set on the internal computer (doubtful i think) or it might just have got some muck in the sensor. (not covinced by this either) Is it possible somethings got broken while he was replacing the joint.. I know very little about ABS - and am wondering who are the best people to sort this out.. I am keen to get it working especially this time of the year with icy roads etc.. Although I am reluctant to take my 12 year old car to the Toyota dealer.. Main dealers are expensive and I have heard Toyota dealers can be almost prohibitive.. Anyone know a good toyota specialist perhaps that might fix it..??

Cheers

Warren..

check the Abs And Speed Sensor Diagnostics sticky note mate.

Fortunately, Toyota provides flash codes to read the ABS codes on the celicas. To check the codes, turn on the ignition, remove the short pin from the ABS check connector (See Fig. 2) and use a jumper to connect terminals Tc and E1.

If the ABS light blinks at a constant rate of two times per second, there are no fault codes stored in memory. That doesn’t necessarily mean everything is OK because something may be having an adverse affect on the operation of the ABS system. This includes low Battery voltage, a "dirty" wheel speed sensor that is not giving a reliable reading or a hydraulic problem in the modulator assembly (See. Fig. 4).

If there are one or more stored codes in memory, the ABS will flash the first two-digit code, then the next and so on, repeating the code(s) as long as the check connector is jumped. The first number of flashes equals the first digit of the code. After a 1.5-second pause, the second number of flashes equals the second digit of the code. If there’s more than one code, there will be a 2.5 second pause before the next two-digit code flashes out.
