P0502 Error code. Vehicle Speed Sensor circuit low. I've looked up the VSS for this specific model and the car has no specific VSS per se. As far as I am aware, the vehicle gauges the speed from 4 ABS sensors behind the wheels. After the car has been driving for a few minutes, the check engine, ABS and traction control light flash up on the dash, and the car tells me to get my brake assist and ABS serviced. I'm not particularly sure where to start. I would assume at each sensor as the ABS fuse hasn't blown.
