I replaced my battery yesterday and now my turn signals don't work. My Xterra and Titan never had this problem. Could it be a blown fuse or relay?

Also my trip odometer re-sets itself every time you turn off the ignition. I'm thinking they are both related?

FYI I searched the forums and found several posts where everything came back. So far after 50 miles no luck.

 

Did you make a quick, clean reconnection or did you fumble with it a little causing sparks, etc? That could have fried the BCM or worse.

 

Quick and clean with no sparks. The only thing I can think of is that we connected a device to hold the memory settings in place. I'm just blown away that something this simple can cause such a PITA,

And thanks for your response.

 

You may have to disconnect the battery overnight to get everything to reset. I can see fuses keeping the turn signals from working but it wouldn't explain the ODO reset.

 

Thanks Dave, I'll give it a try tonight and report back.

 

Hmmm...the turn signals work but the flashers on the dash don't ....

 

doesn't hurt to try a cap discharge , disconnect both cables and attach them together with a visegrip . Leave it like that for 15 min then reattach.

 

Thanks redline, I thought something magical would happen but still have the same issues. I'm thinking about going to the dealer just to get their diagnosis and reverse engineer the repair.

 

Well I just looked at the wire diagram for the dash turn signal bulbs and lucky for you the BCM only controls the exterior turn signals and hazard switch. There is a 10a fuse that controls the interior turn bulbs and buzzer only. I'm not sure what the buzzer is but if that is not working as well then it is pretty good indicator that the fuse is done for. There is three different grounds for this circuit so im pretty sure you can count that out.

The odometer is kinda on its own working with the ECM so it can have your real mileage in the ecm. When you replace the odometer they have to go about it a special way so that numbers cant be ********ted. You have to go to the dealer for this.

I worked at Nissan for little and had a couple odometers just take a crap in all sorts of ways on all models, it wasn't too common though.

 

Well there must be a fuse under the dash because everything on the fuse box is good. I'll take another look at the wiring diagram and see if there is an inline fuse somewhere. Thanks for everyone's posts...keep em coming with any other ideas.

 

PP hit the nail on the head! 10 amp fuse under the dash. Blinkers work and trip meter retains the miles.

Now I can focus on changing the trans fluid and new shoes!

Thanks to all.

 

Sweet!
