I talked to Spal tech support on the phone. They were not aware that this problem could occur. They said maybe this could explain why they had so many customers struggling with these mysterious error codes. They asked me to let them know whether my fix works and makes the codes go away permanently <img src="/forums/images/graemlins/notooth.gif" alt="" />

It's kind of a shame, they discontinued this product because too many people were having error codes they couldn't figure out. It's possible it's because of this very issue. I can see how it could be hard to figure out. I'm an engineer and it took me years of running this device in my vehicle before I tracked down what was going wrong.

Any Update?
