How do you do a factory reset? I tried but it doesn't seem to work.

Please remember that at least one sensor is broken:
syrinx, "IF" you did not want sensor cables inside your car and/or the original/standard cables were not long enough to reach from the ALP CPU (most likely placed under your dash) to your rear ALP sensors, you should have ordered two of the "AL Priority Sensor Extension Cables" @ $29.95 USD each.
