Having done a search to no avail could someone help me on these faults reported by the Durametric?

997 C2S Coupe 2005. 6 speed manual RHD UK


8004 terminal 50 value below lower limit value

8017 right radiator fan motor value below lower limit value

8042 front luggage compartment unlocking implausible signal (info only)

these all reappear after resetting them so 'appear' to be real, but what do I do about them??

what is a 'fan motor value' volts, impedance, current etc?

Any help gratefully accepted :notworthy:

are they causing any issues? i.e. is your car not cooling properly (radiator) or is the frunk not opening when you pull up on the release button? i've noticed that sometimes the codes (esp the "communications" codes" are kind of benign and dont really cause any issues. (just thought i'd mention since you dont really say that it's causing problems, only that you have the codes.)

Thank you very much for the quick replies. Got under it today and had a look see. Fan stuck as you surmised Loren, the luggage compartment issues caused by a stuck micro switch not always turning the light on. Reset and those faults cleared now. No success on the CAN issues though, still coming up. Any idea where I should start looking? Just to top it off it now says reversing light 1 out, and its not they both work??? Ever done something you regret starting? :huh: :eek: :help:
