I got a call today from my mother who said she was getting lights on the dashboard. I went over and sure enough, there were multiple messages in the DIC. Tire pressure low RR tire, LF tire, RF tire, air bag error and more. I turned the key off and plugged in my actron scanner. It turned on being powered from the OBDII connector, and when I turned the key on, eventually got a message on the scanner stating no communication could be established with the car. Where do you start in troubleshooting a condition line this. Obviously, there is power on pin 16 of the OBD II connector since the scanner powered up when I plugged it into the car. Any ideas?
