Cool 1995 E34 540i cannot connect to CAN Bus

Hello and thank you for reading. . . .
I have a 1995 540i that will not communicate with a diagnostics tool. It gets an error of unable to connect or communicate. I have limited knowledge of the CAN bus but Iím not stupid. I notice that the pdf files that used to be accessible are now longer accessible. Iím hoping that someone will have copies of them and email them to be so I can educate myself. I would really like to get to the bottom of this as I need to reset my SRS light as well as install a Dinan chip which needs to be paired to the anti theft system or the car wonít start. In addition if I get a check engine light I will be unable to retrieve the codes causing the problem. If someone could point me in a direction to check something that would be great. Battery is good so itís not that

Default Update

I notice that my right side mirror does not return to the original position when shifting back to drive from reverse. It the seat and mirror memory position controller is the cause of this could this be my connect problem?

Hi, what cable/interface are you using? Most e34 uses ADS. Try this: [Only for registered users... ]
