Scan tool in OBD-I/EEC-IV connector has no connectivity.

[churchandchurch]

On my recently acquired 95 Explorer XLT with V-6, the check engine light comes on while driving. Shut the car off and restart, the light is out only to come back on 5-10 minutes later. Plugged a scan tool into the OBD port and a message comes up: connectivity failure. Anyone know how to cure the connectivity failure so I can read the code? That message will fail me for emissions in Connecticut.

THe obd port is fused. although im not sure what fuse it is, check for a blown one. on alot of vehicles its the same as the cig lighter

Do a pinout of the connector and see if the power pin is hot (pin 16). Info here: http://www.auterraweb.com/obdiipinout.html

Welcome to this forum! I've renamed, and moved your thread to the EEC-IV section. The link in the post above is for OBD-II which is used on the 96-up models. Your 95 model uses EEC-IV. Check the sticky threads on the top of this section for more information.

One thing I would try would be to try to pull codes "the poor man's way" -- with a paper clip and then count the flashes of the check engine light. Test protocol is in the stickies at the top of this forum.

Another thought: which OBD port did you plug into? As noted, your '95 is EEC-IV, but I'm told it still has an OBD-2 port under the steering wheel -- it's just not connected to anything (Ford was anticipating the switch to OBD-2 for the '96 model year I guess). The EEC-IV test port that you want for your '95 is under the hood on the driver's side. In short, make sure you are using the correct test port.

You need to use the old standby method of reading the codes manually using a multimeter or other test methods used on the OBD-I via the engine compartment. The 95 may have OBDII port but its a dummy one.
