Anyone considered disabling the “reverse” signal to the VESS unit so that it only makes the “spaceship” sound (no beep) when forward and reverse?
If you look at the beginning of the thread, I tracked down the reverse signal wires, which are junctioned above the drivers feet. It would take some design work, but would not be difficult
The european VESS panel is interchangeable too and uses all OEM parts - plug and play. No changes to any wiring. Cap1 by rcnesneg posted May 24, 2022 at 3:41 PM
Thanks to everyone who's posted these instructions and follow-ups. I basically followed these instructions, because I have the same switch. I used very small versions (20-22 gauge) of the screw-type taps listed in the detailed post. Thanks to these instructions (particularly the part about both black and green -- I think / hope -- needing to go to ground, and I did this with another tap, instead of to a chassis grounding point), the switch works as intended. On the downside, I have no LED indicating whether the switch is on or off. I guess my 2 questions are 1) how would I know if the LED on the switch is bad (e.g. can I test it with a battery) or 2) would it just be that the red/pink connection might be bad if the switch is OK and I'm getting the intended functionality? To be totally clear, I'm using the stock switch harness, black + green to ground on the car's harness (black wire), red to pink (power) on the car's harness, and blue to blue/black on the car's harness. The yellow wire from the switch harness is not connected to anything. Appreciate any help.
Well, odd follow-up. First, someone broke into our new Niro, smashing the driver's window and pulling out the power button. TikTok Kia Boys, didn't know that they couldn't just hotwire this particular car. After cleaning things up and getting the marred power button back in place (usable until we get a new one), I started the car and suddenly found the light was working on my VESS override button. Now it's exactly as described in other's posts. I'm pretty much positive this change is coincidental, and might have to do with one of those posi-taps sinking into a wire after a day or so, but
BTW: My 2019 Launch Edition doesn't have a loud backup. Was in a parking lot the other day and thought there was a big truck backing up near me. Turns out it was a new Niro EV...so now I know what all this is about...
I actually posted that question tonight to Eric who did the benchtop video of VESS and the canbus scripts he had.
Since the reverse signal is close by in the drivers footwell, the simplest way is to devise a circuit that drives its output low[gnd] for say one second when you shift into reverse, then does the same when you shift out again. You could also retain the button for tight parking lots etc Just slightly beyond my meager electronics skills
This seems like something that could be done pretty easily with a small microcontroller like ESP32 or ESP8266 running ESPHome, which is a simple way to run arbitrary logic based on things like various inputs/outputs going high/low. It also supports modbus, if that's helpful/necessary. My Niro is from 2019, so it doesn't have the obnoxious backup alarm, so I'm probably not going to work on this myself.
Has anyone tried to buy and change the light and traction pannel with one that also has the VESS button?
Yes they are plug and play with no changes to wiring or anything, even if buttons are in a different place. See post #143. The hard part is finding one.
Thank you! I have found that part at a local Kia service, but I wasn't sure it works. As soon as I will buy it, I will put here part no. Thanks!
I'm surprised they have it - depending on where you are? I've heard of US owners ordering them from wrecked cars via proxy buyers in Europe and having a really hard time finding or getting them, usually costing more than $100 for the switch panel out of a wrecked car.
I've got a VIN with VESS and I have ordered on local service. I can't wait to grab it... It's cost is 200$
