A few months back I had a problem that just reoccurred, the speedo, tach and radio stopped working, the mc runs the lights and turn signals work as well as the brake lights. The codes are as follows [the same as last time] P= U1097, pn34309-06 S=U1097, pn68922-00d SP=none, pn67349-04 T =none, pn67348-04A U1097= loss of speedo serial data efi. The last time this happened I removed and cleaned all the fuses and coated them with di-electric grease and re installed them, everything has been working fine until now, I need to find the cause of the problem and correct it before something serious happens. The mc is a 2006 flhtci. I would appreciate any help, as I am not electronically inclined.
