Do any of you guys know anyone that can decode canbus commands? I need a cable to interface between my 2013 Sequoia gauge cluster and a redesigned 2019.

I will have the 2019 cluster Wednesday assuming FedEx is telling the truth.

Thanks in advance!

 

Not a CAN SME but I'd recommend using a Arduino with a CP2515 CAN I/F module to look at the commands. There's probably alot of GitHub Arduino skteches out there with all sorts of code for CAN.

Thanks, I'll take a look!

 

Cluster came!

The main connector looks the same.



Connected the cluster, it acted like it was not connected. 100% nada :P

 

Looks like all the connectors are in different locations.

2008-13 power is pin 18,20 while ground is 40

2018+ power is on 1,2 with main ground on 23



2008-20013

 

Toyota

FWIW, for rewiring the connector I'd recommend getting one of the connector pin extraction tool kits like this one on Amazon

 

Thanks, I have that kit, bought to get the right nav and XM antenna connector into my Kenwood HU after several "compatible" adaptors weren't. I never did get the connector off and ended up cutting & splicing the wire.

That is why I'm working diligently to try to find someone to take my money & make it for me.

Those who can't PAY!

lol

 

FWIW, I was gonna put in a 2006 3G TL radio into my 2005 since it could decode MP3 CD's and had a audio in 3.5mm jack as well.
But no, Acura/Honda/Panasonic changed the physical connector to a totally different connector shell

 

Bastards!

I have gotten either a big NO! or no response from all companies I have found.

 

No one answered so I bought the entire dash wire harness for 500 bucks. Be nice if the cluster harness comes out on its own and its connector into the truck is the same.

 

Sorry you had to get the entire dash harness. It's getting harder and harder to find OEM connectors there are so many types and pinouts along with the constant evolution.

 

So after a day (combined) trying to wrestle the harness I need, I gave up.






I hoped to be able to pull it out & "just" swap the connectors in. I can't find this bulkhead where the 2 connectors going that way seem to be going.



I just cut it as long as I could and gave it power.

Anyone know a software engineer that will tackle the canbus? I will need an emulator at a minimum to tell the cluster all those nonexistent systems are present & happy (may need it to translate other inputs) Won't know until I get the cable end to complete the cable, I have 6 sets coming, 2 each from China, Japan & a company claiming to ship from the US.

 

 

There is a person on the Tundra forum that morphed his 2007 into a 2018 (body, interior every damn thing!) He sent me this comparison so I can terminate the cable, the issue is where 2018 is on the CAN vs wire on 17 down.

Grey are the differences, the dimmer is immaterial as there is a stalk on the 2018+ cluster like for the ODO reset.

 

Got the cable together, it's a mixed bag but progress.

Good news/bad news.

It immediately saw open door when installed.

It sees the 4WD status. Sees gas & volts, no oil or water no tach.

Code U0155 indicates the instrument cluster is not receiving or transmitting messages on the CAN bus.
Push start button came & I found it's harness.
Filling the hole!
lol

Now I need an emulator to send the can data to the right address because the cluster is looking for it at a different address than the truck is sending it to.

nice to see you making progress here! Hoping you get to final goal!

 

This looks like an awesome project, love it!

 

Thanks, been sick all week so no movement but I'll get moving soon.

 

Forgot to post the cluster is alive, working on an interface between the truck & cluster.

 

Nice and Congratulations!!!!

How are you simulating the CAN messages for the tach, speedo, engine temp,.....?

 

Arduino Teensy is taking in the data from the truck & sending the new can addresses to the cluster.


​​​​​​​

Directionals/hazards & cruise do not light up, everything else works.

 

Not sure how you went about the can system, but you can hook up the old cluster and tap into the CAN and see what information it is sending/receiving when you use the turn signals and/or cruise control. That way you will know what signal needs to be output.

 

The addresses were found by someone else, he spent nights & weekends over a year to find them. Sunday a friend is coming over with a 2018 Tundra and I will read it and send it to him. The change is 18+

The directionals/hazards are in a sub harness (second connector) into the dash, I need to look at the wires to figure that out.

 

Woot! Range & distance plotting are enabled!

 

Congrats!!!

 

You've inspired me to pick up a cheap CAN2.0 from BangGood and do some packet sniffing.

It's like looking at the matrix!

Here's a snippet of a 2018 Tundra

^ Have you used/tried WireShark?

 

Nope, that is just serial monitor on the teensy when it's connected to the truck. (between the truck & cluster, seeing the intercommunication)

 

Cruise display is working now!

 

^ Great!!!

 

You should start a go-fund me or business page, that way when you get it working you can sell the complete software package for the retrofit! Make some $$$ and help the tundra community at the same time!

 

The software is not mine, it was developed by someone else so it would be unethical to try to benefit from it beyond my current use in my truck.

 

ahh, my misunderstanding! Very happy to see that you are doing the honorable thing! Best of luck with this, I hope you can get it to 100%!!!!

 

The cluster software is 100% The issues are hardware related, the truck is flex-fuel and the cluster is not, which has the gas gauge off by 1/4+ tank. I have a flex cluster coming Wednesday assuming UPS does not blow it's delivery date.

The steering wheel switches work except the select button in the center of the right switches is not selecting, It may have something to do with the Maestro or something else.

It's annoying but livable.
