Hello Again Customer, I would say a bad CDM is most likely...but before i spent the money on an expensive part such as this I would invest in the Tech2 scan...Alot less money and a 100% verified faulty component...With todays multi component systems I don't like to guess...Rather diagnose it properly and fix it right the 1ST time...jeffrey590
