Need Help

[houston]

my brothers bought a 1990 gen 5 celica gt, but the abs light is on, ive tried to do the codes trick but the light comes on then goes off then comes on constant, giving no codes or even a 'no codes' code, even tried the one where you link 3 of the connectors to find a speed sensor proble, the light flashes 5 times, ok, then just stays on constant for the 2nd part of the code.

help?

did you follow my sticky advise on abs ????

which pins did you short and is there a bridge pin in the diagnostic box?

joined e1 and tc together which brought up no codes, then tried joining e1, tc and ts to try and get a speed sensor code.

ive done the code thing on my old mr2 and it worked, just not for this car, could it be an abs ecu fault?
