From the descriptions it sounds like CAN-BUS issues, but these sort of codes can be seen if your factory radio (headunit) is replaced by one that doesn't support CAN-BUS.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 1 excluded by outcome qualification · 0 adjusted by outcome qualification.

1 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

Does anyone know where to look up what the Foxwell Scanner codes refer to. Please help if you know what the following codes mean. I have a 2006 Boxster S 18,000 miles and I am getting the following codes. Front Control System:- 8042 Implausible signal - Front luggage compartment unlocking POSIP Control System C152 No Display Communication PSM control unit - drive Rear Control System: C128 No Communication - Communication PAS comfort control unit Any help would be appriciated

POST 2Original post

Offhand - nope. 8042? Was there a letter associated with it? What issues are you experiencing and what model Foxwell did you get these error messages from? From the descriptions it sounds like CAN-BUS issues, but these sort of codes can be seen if your factory radio (headunit) is replaced by one that doesn't support CAN-BUS. They are typically in that case harmless.

POST 3Original post

I have a Foxwell NT710 . Codes are exactly as I show them. The car is 100% stock. I tested the battery and it shows that it is healthy. The state of charge was 60% so i charged 100% cleared codes and will drive and see what i get for codes. Thanks for responding to my thread.

POST 4Original post

How did you charge and test to 100%? Did you check voltage after a few hours of leaving the battery standing?

POST 5Original post

Thank you for responding. I have a cheap battery tester. All tests came back good, State of Health, Cranking volts, Battery good etc - except for State of Charge = 60%. So I used my battery tender to charge the battery and then rerun the battery test - all good and Sate of Charge = 100%. I then cleared the codes. I disconnected the negative terminal for a few minutes and then drove the car 15 miles on the highway. All original codes disappeared but now i have code 4444 steering angle sensor not initialized??? Any advise? Thank you.

POST 6Original post

Cheap battery tester is fine, but, again, when did you test it? If it was tested soon after a charge cycle, then it's likely not a valid reading of 100%. Most testers like this try to show SOC by voltage. A lead acid battery drops voltage after a few minutes, and even more after a few hours. This is why any voltage-based test must be done after hours of letting it sit... In the end, I'd go by the age of the battery more than anything else. If it's older than 5 years, then I would expect it's probably weak. If it's EVER been dead, then I'd certainly replace it first, as a weak battery causes all sorts of weird problems on these cars.

POST 7Original post

Thanks for the info, i did not know this. I will charge now and leave for several hours and test again. If not perfect I will replace the battery - probably will replace the battery anyway for peace of mind. Thanks again

POST 8Original post

I charged the battery to 100% and overnight it went down to 60%. I have replaced the battery and all old codes have disappeared . I now have a steering lock code but i am sure it will go away. Thank you for solving my issue.

POST 9Original post

Thanks for posting the resolution to the issue - it's postings like this that show so dramatically the difference between Facebook and a good forum!

POST 10Original post

Agreed, and I also appreciate your detailed report and proper test of the battery, KUDOS! I will certainly reference this for other users, because no matter how often I mention proper testing, people don't do it properly and miss such an obvious and easy to fix issue. And, of course, I'm glad it fixed the problem for you!
