How are you connecting to the OBDII ? (Hardwired, wireless)
What tool are you using to communicate with it?
If you're using some bluetooth adapter it might just be a configuration problem in the software you're using.
The ABS flashing is a known issue with the ELM-el-cheapo bluetooth adapter (like the one I have), some say you can remove a pin on the adapter and it will stop making ABS flash when you use it. read the whole thread if that's what you have.
