2008 FEH Smart Junction Box Reset Button & Flasher Relay?

Postby Tom FEH - May 16th, 2020, 5:18 pm

Hi There,

Let me start with I am not a mechanic by any means so the more basic you can phrase your reply the better for me lol.

Trying to fix a turn signal problem.

Front Turn signal does not flash when turning left or on Hazards. Does come on when headlights are on. I have replaced the bulbs, triple checked them. Switched the sockets from side to side, replaced the multi switch on the steering wheel (it had a problem anyway).

I was told to replace the Flasher Relay, however can not seem to track down where that goes.

Where is this located?

Read a bunch about the Smart Junction Box and someone hit a reset switch by the inside fuse box and their turn signal started working again.

Where exactly is the reset button located?

Thanks for the help I appreciate it. Going a little bonkers over here lol.

Did you say the problem is up front only?

There is no reset switch and no relay. It's all internal logic in 2008+.

Here's a zipped PDF of diagram, I can get pinouts if you need and component locations.

Can you pull any obd2 codes? Though those may need a more advanced scanner than what's available for $50

The reason the parking lights work with your head lights, is because they use a different filament within the bulb. I would pull the bulb and check for 12v on blue wire up front, and the brown wire around back.

Thank you so much for the reply!

Yes we checked the bulb very thoroughly swapping it to the other side to test and it worked!

Good to know that everything is internal to the smart junction box. We were going a little nuts there.

I will check the voltage on the wires as you suggested and check back in.

Thank you!!!
