I am looking at buying a 1991 Sedan DeVille, 4.1, with 119,000 miles. It is throwing an ABS warning light, and for the life of me I cannot find the data port to check to see what is the trouble. Any help appreciated.

Caddy's have their own on-board diagnostics. It is a process to retreive codes, go to link at bottom of main forum page "Repair Manuals" that software can guide you through a complete diagnostic of the entire car
