What should I do if my CAN bus code does not return?
If the code does not return or communication is re-established, then the fuses/connections were most likely your problem. If the code returns, locate the CAN bus communication connections on your vehicle, most importantly the IC-A connector, which is usually behind the dash.
What does can bus’b’code u0074 mean?
U0074: Code U0074 means one or more modules is not able to communicate properly over CAN bus ‘B’ Code U0073 technical details U0073 is monitored when the supply voltage to the modules is in the normal operating range and the vehicle is running.
Why is my scan tool not communicating with my car?
The circuit most often used to communicate with is known as Controller Area Network bus communications, or simply put, CAN bus. Without this CAN bus, control modules cannot exchange information, and your scan tool may not be able to get information from the vehicle, depending on which circuit is affected.
Where is the CAN bus connector on my car?

What do you mean by CAN bus system?
What is CAN Bus System? A Controller Area Network (CAN) refers to a net work of independent controllers. It is a serial communications protocol that efficiently supports distributed real-time control with a very high level of security.
