09+ models only apparently

you know mom has said that before but who is ed?

 

So, here's your year:

And here's my mystery 2.75 gen year:
https://parts.toyota.com/Toyota_2015_Tacoma.html
Why is it different?

 

Okay, but that's not the only year that has that. It may have been the first though. So what you're saying is that I need to look up what sort of signals that unit expects. I'm assuming that it is also the ABS controller as well. We'll see.

 

He did say "09 + "

 

Up to the 15 models. I don't know what else you would need for it besides wiring. I think it is. I haven't read that far into it. I just know that 09+ off road models with Atrac and VSC (don't know what that is) are the only years with that kind of master

 

So I dove down that rabbit hole last night and I found out nothing useful, but some interesting things came to light.

It's not practically feasible to do the electro-hydro ABS swap in my case. Even among my generation of Tacos, my specific setup, the famously lame 4cy AT 4wd, seems to be nearly identical across trim levels. For example, I have an SR5 version of that build and there is no SR5 designation in the parts catalog for my year. That just means that all 4cyl AT 4wds are mechanically equal and a lot of stuff does trade over to the sport and Pro. That's good to know. But almost nothing of the individual processing units or the brake booster are shared with the OR.

However, I DO think it's possible to use an external microcontroller and the wheel speed sensor signal in coordination with the ABS actuator solenoids to create a muuuuuuch more awesomer ABS traction control. The biggest hurdle in a standalone system like that for my application is that the main ABS unit would need upgrades to allow longer run times than 4 seconds. Not an insurmountable issue, but the ABS actuator/controller unit has it's own processor that communicates with the greater CAN system. When it starts to read a certain amount of suspect signals coming from the wheel speed sensors and the solenoid, it will throw codes and lights start turning on.

So again, I'm kind of stuck just learning what each system expects and doing the bare minimum to spoof the signals...? maybe lol

 

Jesus you really did dive in the rabbit hole

 

And that's why we love him

 

Damn right

 

Championship Sunday! Let's go, Kansas City!

 

Hoping for KC vs GB Superbowl!

 

So I swapped out my tails for roommates, right. His flash faster than my originals did. They were also spliced to use pod lights as reverse lights. Would that splicing be causing the fast flash? The splices are still on but the wire for pod lights is cut.

I don't believe it's a bulb problem, but I can always change those out if need.

 

It's possible if they are LED lights. Sometimes the LEDs use voltage levels to change the rate of how a timing capacitor works. I don't know how the empty splice would change that without maybe causing a short though. Do they flash at a different rate than the front or the dash light?

 

Sounds like there is LEDs installed that’ll hyper flash. You can either swap them or add a module for like $10

 

Right on, I will get some bulbs later. The hyper flashing is a bit annoying.

Everything hyper flashes since the new lights.

 

Same. We'll see if GB can pull through last minute. Fingers crossed.

 

My tacoma is officially part tundra...

 

Did a 26 minute oil change today. New personal record
