I did the heater control/readout trick and entered the ABS section. Trouble codes are 125 and 127. 25 and 27 are left front brake sensor.
Do you drop the first digit off the readout? If so, it looks like that's where the problem is for the ABS light coming on.
I believe 1 is for the system number. 2 is Airbag i think. Been a long time since I messed with an OBD1 system.
