2009 IS350 Skid control ECU location
I must be blind or something. I see a few post saying the Skid control ECU is on the passenger side under the glove box...where? Because I’ve tore this whole thing apart and I’m not seeing it. Maybe I need glasses. Perhaps I’m sleep deprived. Or I could just be crazy. At any rate, I can’t find this damn thing. I’d greatly appreciate it if someone could point it out for me.

That’s one of the diagrams I was looking at. This is under the glove box with the panel removed. I might be wrong but I’m pretty sure that in the center is part of the HVAC. The Skid control ECU has multiple connections. I even pulled the kick panel back and looked on the driver side because one diagram showed it over there.

Yeah. I’m thinking it’s either bad or has a loose connection. I have traction control, abs, and afs lights on. I also have code being thrown for
Lost communication with lateral sensor module
Brake boost sensor circuit range/performance
Zero point calibration of yaw rate sensor undone
Open or short in front speed sensor
Lost communication with yaw rate sensor

Second you can do a Zero point calibration. The procedure is here Post# 10.

Hopefully it just got out of whack. Someone posted before of this issue. The Zero point calibration seemed to fix it.

You can start by checking the abs speed sensors on the front. With an OHM meter check resistance on both sides. To see if any are damaged.

The first thing I did was the recalibration. The second was check the speed sensors. One of them had a value that was slightly off so I went ahead and replaced them all since I was already going to have the wheels off to replace the brakes and rotors. I appreciate the info though. I will try the zero point calibration again

Well if you find it let me know. I can see a black box above the glove box that appears to be about the right size so I’m going to pull that out and check in the next couple days. 🤞
Yeah I was think the same thing. Maybe it's above the airbag, or next to the AC amplifier. That's the only probability I can think of.
