Obd2 port - no communication with ecu

Post by MarcusHansen21 »

Hey, so I have recently got my hand on a polo 6n2 1.4 16v. The abs light is on and I'm suspecting a bad abs sensor, but I plugged in my obd reader from autophix the om126 which has helped me on many other cars. But I says that there is no communication with the ecu.

I have had the obd2 port out and checked all the wires especially pin 7 for the ecu/can whatever and they look good.

Fuse 15 iirc was also good so I'm a bit confused as to why, any help would be appreciated :)

If you have an aftermarket radio fitted, unplug it to rule out interference with the K-Line wire https://www.ross-tech.com/vag-com/after ... radio.html
