Default Bus Error
Got my new audio system in, Sony MEX-M70BT with Metra bracket, ASWC-1 and Biketronics 4180, and seems to be working after I ran a ground wire to the battery for the ASWC-1. Went for a ride the other day and started to get a Bus Error. Checked it with my Powervision and found a U1300, serial data lowEFI and U1301, serial data open/ high EFI,Tachometer & Speedometer U1 300 HIST,Tachometer & Speedometer U1 301 HIST. Cleared it and it came back. Gonna pull the fairing today and look for bad connections, etc... Anything else anyone can think of to check? What causes these codes? I posted this in the audio section since it happened after I put the system in but didn't get any responses so thought I would try here. Thanks for any help or suggestions!

Reseated most of the connectors and cleared the fault. Went for a ride and so far the fault hasn't come back.
