I had my EDFC recently installed and it just stopped working. I went to check if maybe a connection got loose but everything was still wired up.

The main power (constant) was hooked up to a red wire connected to a Black terminal sitting ontop of a Brown terminal mounted on the Break Pedal.

I checked for voltage but nada, I then connected the EFC main power to a seperate circuit and all worked.

Now I am worried why the other wire does not have voltage and I'm trying to find out what circuit it is.

Again on the break pedal arm are two terminals one lower brown and one upper black. The Black one has a red wire....that's the one I need to figure out. Most likely a fuse blew, I just don't want to go through every fuse.

Help would be appreciated

 

Sounds like you're talking about the "stop lamp switch" which senses whether the brake pedal is depressed or released.

There is a red wire with a yellow stripe on that assembly that is fed power. The other wire is purple with a blue stripe on it which leads back to the tail lamps. I'm assuming you have the manual transmission otherwise the automatic has four wires coming from a different switch.

If you blew a fuse in the brake lights when you depress the brake pedal you tail lights shouldn't light - this is an easy check to do with someone else or by backing yourself up to a garage door or wall after dark and looking for the lights.

Fuse Box J/B fuse #20 is the one you need if it's blown. Fuse box J/B is the top one inside the port side (driver' side) kick panel.



The fuse has battery power supplied to it so it should have power with or without the key in the slot.

What's a EDFC?

Edited to add: Electronic Damping Force Controller (google is your friend too)

 

you're correct I figured it out this morning, here's what happened:

I have a switch underneath the dash that allows me to turn off the break lights for better burnouts....that is from before I had line locks...When my installer hooked up my full throttle shift he must have accidently hit that button and in return switching off that light....I turned it back on this morning and all worked fine.
I'm glad I did however moved the EDFC power line to a different circuit in case I'll ever use this switch again...

Thanks for your help though
