Fault Codes - Help!
Hesitant to post this but this is uncharted water for me. Had some coding done over the weekend by Alex @ Alpine. While in there he pulled up a bunch of fault codes that I was previously unaware of. He said they are all low risk and likely related to the communications system of the car. He said they could not be deleted and likely something was broken. The car runs perfectly and I never would have known these existed without him digging them up. I try to maintain this car as best I can and don't like knowing these codes exist. Before I go one by one and try and troubleshoot each of these I wanted to post them here and see if anyone on the forums had some experience with any of these particular codes. Thank you in advance for any help and guidance.

Shadow codes come and go all the time, usually due to random voltage fluctuations or other transient issues. If there are no warnings coming up and all your systems work, then simply clear these and pay no further mind.

Thank you both for the feedback. Hoping that is the case. I don't have any dash warnings at all. I will see if I can go back and clear them and we keep an eye on things. I did have an increased battery discharge code pop up after a wash last weekend but it went away immediately and has not been back since. Could have been the culprit?

Yup, absolutely. If the voltage dropped down enough to trigger that warning, it's certainly been low enough for a while to throw shadow codes in various modules.
You can see descriptions of those codes by scanning those individual modules in INPA or full scan in ISTA. I'd be willing to bet many of those are for low voltage. Time to plug in a trickle charger overnight if your car isn't being driven enough.

I haven't replaced the battery. Just did a trickle charge for $60. No issues since. |

I went through and installed INPA so I could read the codes myself and still have low level fault codes after clearing. All remaining codes are related to K-CAN wire fault or low line fault. From my surface level research it seems this could be related to the battery or a kink/damage in the K-CAN wires somewhere in the system? Does anyone have experience with this? All systems are still functioning perfectly with no warning lights so I think I'm going to stay the course for the time being.
