As the title says, i'm curious to know if the Turbo Coupe actually accepts OBD1 scan tools!

That would be great if so! It'd make diagnostic work a lot easier lol

IIRC, OBD2 (on-board diagnostics, 2nd generation) wasn't officially/legally required on vehicles sold in the U.S. until '96, and ~ altho there WERE a couple of manufacturers that voluntarily implemented it on '95 cars ~ the strategy wasn't even known or thought about yet in '87. Soooo.......YES, 1st-gen diagnostics (OBD1?) were all that was/is available for your TC.

Accessing/interfacing with it requires a Ford "Star" scanner or a generic scanner with the appropriate adapter plug(s). The connections (plugs at the end of two separate wires) are under the hood on either the passenger or driver side, usually near the firewall. One plug is trapezoidal in shape that's about 2-in wide and the other is a much-smaller single-wire plug. Both were originally held by a single plastic "holder", but may be dangling loose ~ and they'll both be coming out of a common harness.

Other than buying/using a purpose-built Ford-compatible EEC-IV scanner to access any stored codes, it's also possible to "jump" between two pins on the connectors, turn on the ign switch and count the number & spacing of "CEL" (check-engine light) flashes on yer instrument cluster (LINK - LINK). The flashes can then be interpolated into one or several DTC's (diagnostic trouble codes) that each match up to specific faults.  Smile

Note an EEC-IV code scanner is only about $25 so it's a pretty cheap means of scanning for codes.

Ford 2.3T cars went out of production before OBD1. Few people, enthusiasts at least, ever bothered to purchase a Ford-specific pre-OBDII code scanner because all it takes is a piece of wire and a working CEL to get the codes. The CEL can be substituted in desperation for a 99¢ 12v test light.
