I did not know that this was possible, but I've read from a couple of sources that by grounding the number 9 pin (bottom left of the diagnostic plug port) it will result in flashing and thus the ability to read the ABS codes. Is this so? Sounds too good to be true, honestly. It would save buying a costly ABS code reader. Also, part stores don't have the ability to read ABS codes as far as I know. I have a Nissan with ABS and SLIP lights on. So what does the collective say?
