Drive Monitor Wiring - MPG

You might be on the right track with replacing the accessory meter.

One guy here mentioned he had to replace his Canadian cluster with a US one. https://www.tundratalk.net/threads/accessory-meter-not-working.588938/

A lot of info here including part number for accessory meter. I think either the accessory meter or the instrument cluster needs to be replaced. Not 100% sure which however. The one forum mentions the accessory meter

 

Well...I've bought Both pieces used from Ebay.
A speedo cluster from a 2011 with 17k miles, with the tow pkg, like mine. $95
And the temp/ clock meter from a 2012 model for $65 .
If neither one of these fix the problem..
I'm done with it. I'm giving up
After reading the post you sent me about the other guy having the same issue AND his truck was from Canada also...gives me some pretty good hope.

 

All of your wiring is in place and correct so it has to be an ECU problem. One or both of those should fix it hopefully

 

I just struck out with the accessory meter swap. Got the one from Ebay yesterday, swapped it out today and same result..nothing .
So...the speedo cluster should be here sometime this week and that's the last straw. Sure hope it fixes the problem.

 

BINGO.... Problem solved.
Put in the used speedo cluster a little while ago and I now have ALL the functions. Took it for a few mile drive and see how bad the AVG. gas mpg is. .I was also a little surprised that the 103k miles that was on my truck, has disappeared. It now shows having only 17k miles on it. That's what was on the crashed truck this cluster came from.
Shows me how easy chop shop crooks can cheat people. I thought my trucks mileage would transfer to the new cluster.

 

Awesome! I guess Canadian clusters don’t support the accessory monitor.

Unfortunately the Milage data is stored in the cluster. Your new one will have to be corrected to match the truck. I can do this for you but I have to have the cluster in hand to change the memeory in the chip.

Do the part numbers on the clusters match? You need to make sure it matches so fuel gauge and other things will work correctly

 

Kaner and baraynavab, thanks a ton for giving all needed info for this swap. I wanted to follow up with my experience and what I found just to add to this thread and share my appreciation. My truck being a 2007 SR5 RCSB never had the option for optitron gauges, I purchased my cluster from Tanin Auto (linked below), I paid around $460 for it. I also bought a great condition used info button stack for $40. I went into this with no idea if it would work and it did minus the info selection option that is simple but necessary when getting this cluster. Enough threads led me to this page of which did the best job clearly showing what needs to happen, and doing so allowed the display and buttons to function properly. I found that with the old SR5 cluster with the new wires and button stack allowed the display next to the clock to cycle through options that it never did before but they stop cycling when the optitron cluster is installed. I am thrilled to have this upgrade in my truck and I appreciate the time put into this thread.

I love the TRAIN HORN button on the dashboard. Wish I had one

 

It’s quite loud, also has the benefit of on board air

 

Mine....

 

So I would like to add one more successful Drive motor switch addition to the tundra family collection, I have a 2007 Toyota Tundra regular cab, Originally with a Drive motor switch that had just the Fahrenheit button. I used the 0C090 option switch and added the two wires as stated on this forum. I also included sonar to my truck, and the switch is in full working operation. Thank you guys so much for the hard work and research to make the Modification optional.

 

I know this thread is old but I was hoping for a little bit of help from those who have done the mod with a COLUMN SHIFTER.
I was all excited to get my wiring done last year when I got stuck trying to get the cluster out. The shifter is completely in the way when put in Park.
I have read about possibly removing the upper dust cover on the steering wheel but I couldn't for the life of me find how to get it off without breaking something.
If anybody would have some guidance on how to go about it, would be much appreciated!
