Hoping someone can help find this issue.

'16 RGS on which I installed a '16 RGU main harness so as to have passenger communications and rear speakers

Dealer flashed for rear speakers and all functions work BUT we have a slight whine when the intercom or CB is active

There is a code;

U0002: 0xxx10x0
Vehicle CAN Perf Error
Odometer 14827282 m...
Test Failure: 102
Age First: 22
Age Last: 8

If I disconnect the 16 pin plug at the tour pak or the rider's communication harness that runs to the console the whine is still there which tells me the tour pak harness and the console harness are good.

I've double checked all of my connections and checked the grounds, all seem good and tight.

At the same time (which I should not have done) I installed a set of 12" handlebars, all functions work

Everything is working just the whine and the DTC.


Are the only grounds right in front of the battery and the engine? I was careful to make sure I got them all

Thanks for any help
