How to access ECM/ECU?

Does anyone have any instructions or advice for getting at the ECM in the front passenger area of the truck of a third gen? I have an 2018 offroad access cab.

Mine is making some buzzing noises and I'm going to try to dampen it, but I don't want to go tearing into stuff without an idea of how to get to it.

 

Subd, I would like to make the buzzing stop also.

 

I saw in another thread that a dealership stopped it by installing some felt around the ECM mounts.

 

Saw that also. Have the same question you've got now.

 

Best I can do for you:

DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
3. REMOVE INSTRUMENT SIDE PANEL RH
4. REMOVE GLOVE COMPARTMENT PLATE
5. REMOVE LOWER NO. 2 INSTRUMENT PANEL AIRBAG ASSEMBLY
6. REMOVE LOWER INSTRUMENT PANEL ASSEMBLY
7. REMOVE ECM
(a) Disengage the clamp to separate the wire harness.
(b) Disconnect the 5 connectors.
(c) Remove the 2 bolts, nut and ECM from the instrument panel reinforcement assembly.

 

I had to access the 4wd ECU behind the glovebox for the 2 wheel low mod. I took pictures for my writeup, but they are kind of dark. See PDF in https://www.tacomaworld.com/threads/lock-stock-and-2wheel-low-3rd-gen-diy-mod.536677/#post-17273014

 

Note, I updated my pics a bit in the pdf. Brightened them up a bit

 

Awesome, that's what I was looking for .. thanks
