let me see if i remember your issue - you had the main issue with flickering, right? the lights were lighting up normal, parking, brake, turn signals... but flickering and the message on the dash, right?

for the message, if the resistor does not resolve the issue, you will need to turn off COLD MONITORING, HOT MONITORING and REPORTING OF FAULTS of the rear lights - the LCM will still register errors for the LEDs but will NOT report those errors to the dash.

for flickering... cold monitoring may reduce the flickering slightly but the main reason for it is the BDF... i do not know which values need to be entered into the system to eliminate the BFD flickering, if the capacitor does not help - but it is doable from within the programming as well...
