2016 SR5 - Weird Electrical Woes

Hi all,

my taco has been having some strange electrical issues and I’m starting to think they may be related. I am the second owner @ 65k miles and have noticed issues intermittently for the past year since owning it.

1. Headlights don’t turn on upon start up. Restart and headlights work fine. (Happened ~5x year)

2. Turn signals & hazards stop working at the same time. (5x year and recently stopped working entirely)

3. Key fob is intermittent and getting worse with the cold. (Happened like 50x starting in the fall)

so that’s all of it. The biggest issue is the turn signals, if nothing else is resolved I need this fixed .

thanks!!!

 

Any aftermarket electrical items at all installed on the truck?

 

Have you tried installing new batteries in the fob?

 

1 & 2) If you have an actual metal key (not push to start) try wiggling the key/ignition lock around a bit then next time the headlights/turn signals/hazards act up. Old cars (Chrysler mostly) would do that when the ignition switch got worn, especially happened to people who had massive heavy rings of keys.

3) Sounds like your fob needs new batteries.

 

My truck told me the other day that my key fob battery was low on the center display, surprised the heck out of me. This is the best damn truck I’ve ever owned.

 

New Combination Meter

 

only speakers

not yet, how do you even access the fob batteries?

 

God I hope not….. $500?

 

Turn/Hazard relay is part of the Combo Meter (non-removable)

 

bad or loose ground?

 

OP, do you have a friend with a code scanner?

 

I have access to an OBD2 scanner, I’ll give that a shot

 

Should be explained in your Owner's Manual.
Pry the fob apart to expose the batteries.

 

yeah turns out it’s a b1507 code for the gauge cluster. How much of a PITA is this to replace?

 

Easy peasy, but you'll need the dealer to program the milage ($) or a sticker from DMV stating combo meter change (milage difference).

 

Replaced the cluster this morning and the truck works fine now. I was able to find a vendor that does mileage programming for the gauge clusters they sell. Thanks!

 

That is awesome!!!

 

Did you open the rear panel of the removed combo meter?
