My '90 has had the ABS light (constantly) on for a long time, took it to my local garage I dealt with for many years to have the code read, he said he got code "13" but, didn't know what it was (other than it wasn't a sensor), he was going to call FORD to get the code & let me know. Anyone got info. on this code ?, I will let you know what he tells me. Ed '90 180K
