Let me start off by saying that these codes are a recent development. I've had an aftermarket remote start system installed for almost 2 years and these codes are preventing it from working. I recently installed an aftermarket head unit about 4 months ago as well. Everything was working fine up until about a week ago. I can clear the codes and the remote start will work for about a day until the codes come back. I tested the battery yesterday and it's still in good condition so I'm not sure what can be causing these codes considering everything I've had installed was all working perfectly until last week. Any help figuring out what could be causing this would be much appreciated.
