Does any one know if shorting pin 3 and pin 1 on the plug for the tech2under the steering colum actually resets the SDM or breaks it??? Pin 3 is where the SDM communicates with the PCM and ECU blah blah but i think pin 1 is possiably earth but not sure , either way if Pin 1 is earth then i dont think it would be good for the SDM if it is shorted to earlth Cheers if anyone can help :yeah:
After doing a search I found you can only reset the SDM with a tech 2, but I would like to know what SDM stands for if anyone knows.
from gregory manual it say 6 is earth because if you want to see fault codes you bridge 5 and 6. 5 is diagnostic and 6 is earth. not sure if you can reset the SDM like that
