I believe you meant C1380. If that isn't correct, let me know.
Here is how things work. The stability control ECU inputs the stop light switch signal to detect the brake operation. The skid control ECU monitors the stop light. The code is set when the ECU recognizes the stop light is not working properly.
Here is a list of possible causes:
Faulty Stop light Stop light harness
Stop light circuit poor electrical connection
Faulty Stop light Control Relay
Faulty Skid Control ECU or actuator
I need you to check the stop light control relay. I attached a pic of it below. It is located under the hood.
If there is another relay with the same part number, switch them to see if that chances things. If not, here is a link that explains how to test a relay:
Let me know what you find.
