The code is U1301 not 3101 ! This is a code for the class 2 serial data bus , the modules on this vehicle all communicate , share information on this data bus ! If you don't know anything about multiplexing or data bus communications you need to take this to a pro who does ! Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. In addition to this, Node Alive (State of Health) messages are transmitted by each module on the class 2 serial data circuit about once every two seconds. When the module detects no messages and a high voltage on the class 2 serial data circuit for approximately three seconds, U1301 is set and the setting of all other class 2 serial communication DTCs is inhibited.
