To2 with 2018 corolla

Post by Killfree »

Hi, I have a 2018 corolla with the 6.1 inch radio. I got a kenwood ddx5706s with a maestro rr and an hrn-rr-to2. My problem is that I cant find the yellow and red cable that should be on my obd2 cable. My instruction manual does say that they need to be connected. Everything work but I have no information for my gauges, are they supported on that car?

Also, My backup camera still has the stock parking lines overlapsing my new unit lines. Are they comming directly from the oem camera? Or can I desactivate them?

Thank for help

Gauges are supported. If you look on the white flag on your t-harness, what version does it say you have?

There is not a way to turn off the static parking lines. If you turn off the parking lines in the Kenwood menu, you will lose them all.

When I go into the gauges app on my kenwood, it’s saying that obd2 is disabled

It should say something like v1.5, 1.6, etc.

If you don't have the twisted set of can wires going to the obd2, then you have an older version of the harness, and the can is being connected behind the radio. Look on the 28-pin plug of the TO2. You should see yellow/brown and red/brown wires. If you trace across the plug to the OEM side of those wires, are there any wires present? If not, that is the issue. You would need to extend these wires and run them down to the OBD2 for the gauges to work. Red/brown to pin 6 at the OBD2 and yellow/brown to pin 14 of the OBD2.

Hello, I have a 2017 Corolla with a Kenwood DMX4707S. I have the maestro RR plus TO2 harness version 2.0 I have everything wired according to the diagram but I have no gauges or menu pop up on my Kenwood. According to the previous post the brown red and brown yellow wire are supposed to match up but on this harness they do not, what do I need to do to make the gauges work.

So I take the yellow/brown and red/brown wires from the to2 harness, remove them then extend them into OBD2? Do you have any pictures or videos to show the steps?

If you look on your t-harness, do the red/brown and yellow/brown wires have a 2-pin plug attached to them, or is it just wires running into the harness?
