We flashed the Headlight Control Module. We know that worked because all of the other functions that were giving errors are now working. The LED Turn Signal module and LED Cornering Light module are controlled by the Headlight Control module. They plug in with connectors to the headlight assembly. The Cornering Light module works properly, it's just the Turn Signals that do not.
We could not find anything in ESYS that specifies the Turn Signal Module.
I just ordered a used OEM Turn Signal module and will see if that works.
