66-96 Ford Broncos - Early & Full Size

OBD fuse, 95 Bronco

Recommended Posts

I have a 95 Bronco. The check engine light came on but the scanner can't read the code. I was told it could be the fuse but I can't seem to locate the fuse. The cigarette lighter works cause I plug my cell charger into it.

I'd also like to mention that I recently had the transmission worked on. I read somewhere it could be the transmission control switch wiring causing a fuse to blow

Any suggestions on what is causing the issue?

Yo Dameon,

Welcome!

Here ya go!

Code reader or self test stops, try this "Scan Tool Won't Initiate Self-Test Due to Poor Grounds", Corroded Wiring, etc.; read more on how to Ground the STI & Proceed w/ Test;

Dwell on items that can be easily tested such as battery voltage, etc.

FYI;

When the ignition switch is ON, it turns the EEC power relay ON.

The EEC power relay provides power to the powertrain control module (PCM) .

Check the relay, as long as horn can honk,  swap horn relay in place of EEC power relay.

 EEC IV Power Relay is served by Maxi Fuse I (eye) in under hood power distribution box (PDB) .

AND Maxi Fuse U serves Ignition Sys, PCM Power Relay Coil.

Transmission Control Indicator Light (TCIL) Troubleshooting in 92-96; "...because wiring may be misrouted causing a short in the steering column and a blown #17 fuse in TSB 92-22-5 for 92 Bronco & all Light Trucks.

Had almost the  same situation in my 96 a few yrs ago;

Fuse #17 blew due to a harness short under steering column that affected the OD Cancel Light (it blinked randomly, no Trouble Codes or tranny malfunctions though)

Here is a TSB that deals with it; for a 92 though.. and may apply... even tho year range is off... and your OD sw is in dash and 96's are on end of tranny stalk....but... itsa pure guess on my part..and it's an ez no $ check anyhowz
