Update it was the soldering on the 4 pin connection near the data logging port, seems the green light on d3 is linked to those 4 pins somehow because once the connection was fixed the light started working but only while the data logging cable is plugged in. Hope this helps anyone struggling in the ...

I just need to know if the D3 light means anything if not I can figure out the rest myself it just seems like it has correlation to my issue because it all started when that light went out. Thank you

I also brought it to a tuner who tested the ecu with a socket tester and they were all good.

No unfortunately I dont have anyone else to compare or test out my s300 on but it was perfectly running one day then all of a sudden it would stall as soon as I started it but after a couple tries it ran fine and I could datalog after a few minutes the D3 light went out and the car died. Ive posted ...

There is no datalog showing the issue because the computer isn’t getting any readings it’s all just blank but it says it’s online and I can press the button but nothing changes even say the battery volt is 0.0

Sorry about the long delay between replies, I’ve used the same tune that I’m using now and started the afr tuning process so I know it isn’t the tune but one day it just stopped reading the Vehicle Speed then 2 days later no sensors showed any data. I’ve tested the ecu and I know the connections are ...

Yeah J12 has been cut like I said it was working before I just want to know what the lights mean if anything because the green light on d3 was solid then I turned the car off and back on it will only flash for a second when the ignition is switched and the car starts but stalls immediately.

Does anyone know what the lights on the s300 v3 indicate? D1 stays green ,D2 flashes red when datalogging it’s a solid red and D3 flashes green for a sec when I turn the ignition then goes out not sure if that’s what’s supposed to happen but for some reason it won’t show any sensor readings even tho ...

Did you ever figure out the problem?? The same thing is happening to me, same engine, ecu and situation
