2016 Toyota Tacoma Flasher Relay Location?

No, read his initial post. It's an integral part of the Guage cluster. Think of it like any other relay or flasher. This one just so happens to be soldered to the PCB of the combination meter, instead of plugged into a fuse box. Yes there should be a way to test to 100% confirm it's the flasher. Need a meter, knowledge of reading a schematic and some wire probes.

 

Getting a buddy to exchange his and test is an option. Programing/registering the new one I don't have the full info.

 

There is also the option of adding a 2nd Gen Hazard/Turn relay. Simple to do with the correct parts, but the cost might be near a replacement Combination Meter.

 

Thinking this might be my best option. Thanks for the info.

One more question just for clarification for me. When you refer to Combiniation meter, is the Combination Meter just the board that's on the back of the gauge cluster? Or are they one in the same? So the flasher relay is sodered to the combination meter, which is then attached to the back of gauge cluster?

 

C10 is the hazards/turns circuit attachment.
C9 is Speed, RPM, Temp, Fuel, CEL, etc.

If I may, I'd just like to point out a couple of observations.

1) I understand about not buying the part until you know where the problem is. Only thing you can do is prove that the lighting wiring is good by doing the continuity test. (eliminate everything but the electronics)
2) I believe that the Combination Meter and the MBECU are separate devices. Pretty sure that the wires connect to the MBECU. Not sure how the CM plays into this? You may ask Caribe directly. I tried but I don't think he likes me all that much.

Not to confuse this situation anymore, but just trying to help you spend your money wisely. As I mentioned, the hard wiring appears to be connected directly to the MBECU, from what I see this electronics device contains the relay for flashing? Since , as far as I can see, the CM only has a Data cable connected to it from the MBECU. This leads me to believe that it is working like a processor? And the work is being done by the MBECU. Being that you report that you are getting "some" activity at the tail lights, and if my suspicions are correct about the way these electronics devices work, I suspect that the "controller" is functioning correctly (asking the relay to flash). But the relay isn't doing it's job correctly. Sorry I can't help you any further as my specialty here is in the actual wiring and not how the electronics work. I'll leave you in the capable hands of Caribe for that. Maybe if you say "Pretty Please" he will respond to these observations.

 

Pretty sure they're connected with can high and can low. Usually the combination meter is the intermediary to other modules, like abs, skid control, TCM, ECU etc.

 

Best way to learn about systems like that is "theory and operation". It'll tell you what's expected and what to expect when testing shit like that.

 

The combination meter is the gauge cluster. It's a single non-serviceable part as far as toyota is concerned. I don't think there is a turn signal "relay" anymore. The sound coming from the cluster is definitely not electro-mechanical. I suspect this is a solid state component now and the sound is emulated.

 

Pretty sure @MESO has been balls deep in the cluster. Maybe he's seen the flasher

 

As have I, there is no flasher/relay in the combination meter, it's solid state and the clicking sound is emitted from a piezo

 

So this makes it seem like @PhenixFord was saying is correct, and the relay is in fact located on the MBECU. I may have to haul that part out this weekend and see if I can see any relays attached to that board. First step would have to be to pin point exactly where the relay is located I guess.

Too bad Toyota didn't make these parts easier to service like in the older models!

 

That would be incorrect. You are overthinking it.

 

Yeah, we know it's not easily removable, but couldn't the solid state be unsoldered and resoldered? Did you add that conformal coating or was it already on there?

 

Please explain.

 

Main Body Electronic Control Unit:

No relays. And not in the Combination Meter.

 

Just reread again, so there is no 'relay', just a solid state chips that does the work of a relay, including making the clicking noise of the relay, but does not actually use a true relay?

 

That's correct the Combination Meter (cluster) is what flashes the signal lights, there is not a traditional relay or flasher inside. There are some 5v voltage regulators, diodes and such iirc. No "fuses" that I could find either.
