    Digital Dashboard Progress

    For the last month or so I have been very invested in finding a way to update the style of the 2015 instrument cluster in my RCSB. It is no secret the biggest downfall of the 2014-2017 cluster is the lack of a digital speedometer and the graphics and styling are not exactly modern. I decided I had a few options, buy and install a 2018+ Tundra instrument cluster, OR design my own style and incorporate it into my current 2015 cluster. For the past several weeks I have been exploring both options.

    Most of my time has been directed towards simply replacing the 3.5in display in the center of my 2015 cluster. I don't have the skill set to reprogram Toyotas factory setup BUT I can replace the Toyota screen with my own running code and a design I created. If done properly most people would have no idea it had been changed.

    After 6 weeks, this is my current prototype and I made the first drive with it in the truck last night.



    As you can see from the photos the prototype is a 3.5in display simply taped over the Toyota screen (for now) on my cluster. If you look closely you can see the power and video signal cables feeding the display. The display is running a custom GUI with a TRD Pro background image and digital text gauges for Speedometer, Gear Indicator, Odometer, and Exterior temp. The data for all of the gauges is coming from the CAN bus signals in the truck and is the same information passed between the ECUs to let the vehicle function.

    Here is a link to a video showing it working. https://streamable.com/79bzk0 My camera doesn't pick up the colors well but the Gear indicators are color coded the same as the factory Toyota.

    I have plans to add more pages to the display that you can shuffle through with the steering wheel buttons. Eventually I would like to have a page with Current and Avg MPG displayed, Fuel Level in Gallons, Range in Miles, Digital RPM, Digital Coolant Temp, Throttle % ect. I have already reversed engineering most of the CAN bus signals for all of these I just need to create the graphics to display them. I need to add indicators for Cruise control ON and SET also but I have found these CAN signals already also.

    Here is a picture in the daylight where you can see how rough of a prototype the current install is.



    The final step will be finding a way to permanent install it in place of the current display in the cluster. IF that is done right and nice it will look factory from Toyota hopefully.

    I have been making progress with the 2018+ Instrument Cluster as well. The thought is eventually it could be adapted to run in a 2014-2017 truck

    When Toyota added the Safety Sense System in 2018, they added several new ECUs on the CAN bus network. Things like forward facing camera, forward radar, rear cross traffic alert ect.

    If the 2018+ Cluster does not see these ECUs present in the truck it will throw all kinds of errors. I have spent extensive time generating CAN bus signals to send to the 2018+ cluster to "spoof" the Toyota Safety Sense ECUs.

    Unfortunately some of the CAN signals that run the gauges have also changed. For example RPM is on a different CAN address in the 2018 than it was on the 2014-2017. So if the 2018+ Cluster is ever going to work it will need a CAN translator in line to take the 2014-2017 RPM signal and convert it to the style the 2018+ cluster is looking for.


    This is the 2018+ Cluster running from CAN signals sent from my laptop.

    Is this something you're still working on? Would be amazing if the new cluster could be retrofit, so annoying to not have a digital speedo...

    Yes, I actually started an updated thread a few days ago. https://www.tundras.com/threads/dig...uld-you-like-to-see-speed-rpm-mpg-ect.100691/

    Most of my work has been with building an replacement display for the 2014-2017 cluster. However if I really wanted I could most likely program a CAN translator to the put inline with the 2018+ cluster to make it work on a 2014-2017 truck.

    If you get the 2018 cluster to work that will become the #1 mod on my list, currently trying to find a way to fit the 2014 and up cluster in the 2nd gens without it looking like total trash

    The dash is so different you will most likely need alot of custom fiberglass work. I just put an entire 2014+ dash in my 2007 instead.

    I have the 2018 cluster working it just has alot of warning messages from the Front radar and other safety ecus you have to spoof. Basically I just send messages telling the cluster the radar is working and everything is ok, however my truck doesn't even have radar.

    This is probably a dumb question but could you just take it apart and remove/destroy the bulbs for the stuff you don't even have, wouldn't that be the majority of the warning lights that are coming up. Say there was a TPMS light that didn't turn off and you don't even have TMPS, just take the bulb out, it has no business being there anyway if you don't even have that feature.

    Most of it its all surface mount leds, however the warnings I am talking about a messages on the LCD screen.

    That makes more sense, I guess the only option is to spoof it with false signals

    If you don't mind whenever you get a chance could you figure what these dimensions are
