I got your message the only thing is usually you start at the first code the problem is l think you might have read the blinks wrong you said the first one is 2124 the problem is l can not find that code in the book you might have to go back in and count again hate to tell you that. The only code that l see is 1124 throttle control moter relay circuit. But that is not the first code so l would not be concerned at the present time
