I'd start with the ABS module connectors.

Right - but I guess I'm wondering (and didn't ask this) - do codes get thrown and the CEL doesn't light up? Is that normal?

Yes. A lot of DTCs don't light up the CEL. Even if it is related to an engine problem. Depends on how severe the ECM thinks the problem is.

ABS is not part of the engine. You may have a brake or other problem light that you didn't notice.

I probably have dirty MAFs as my car sometimes goes into limp mode when I first start her up with no cel light. Every few months, I will get the cel light and when I hook up my obd ii scanner, it gives me the MAF code, which Iíll clear out. So no, a cel light will not always come on.

I have this same dtc show up in mine as well but it's just a pending code and has stayed that way for a very long time, anybody ever figure this out? Doesn't seem to effect the car, but was more curious what i should be looking for if there really is a problem, battery is good and reads a consistent 13.6-13.8v when the car is running

I've had this for a while too. Recently changed my battery, but I think the issue is when I had my rotors and pads swapped.

It has never given me a real problem. Shop mechanic and tuner also said there's no major alarm.

its a code that says the supply voltage is out of range. check the ring terminal connector on the alternator and the alternator cable for corrosion. i had it light on fire once because the alternator was trying to bring up the cars voltage through the corrosion. if your battery gauge does weird inconsistent drops in voltage to like 12-13v and sometimes is up near 15-16v it could be the issue. mine did it for a year before the cable melted. if i drove it infrequently i was always fitting bad batteries because it would be either under charged or having 16v thrown at it. i also ended up replacing the alternator but if you catch it earlier it might be ok. unbolt the cable from the alternator and check that it is still flexable and the electrical tape hasnt hardened if it has cut the tape back a bit slide the rubber boot out of the way and see if the cable is turning green from corrosion. if it is replace it. then check the ring terminal and the post on the alternator for signs of arcing or corrosion, clean up if its there and if the post or nut are corroded replace the nut on the alternator where the connector seats too. use a bit of dielectric grease or the red spray for battery terminals, re tape the end of the wire if it isnt corroded and reinstal. if the cable is corroded you will have to replace it.

Replaced the alternator on the Z a little less than a year ago now and checked everything while i was doing it, don't remember if the nut that holds the cable on was corroded but the cable itself was still plenty flexible with no signs of corrosion. I can take a look again, but my voltage readings are super consistent so i don't think it's that. Only other thing i can think of is i know the two grooved idler pulleys are on their way out, would that cause enough drag on the belt though to cause the alternator to not behave properly?

Probably not it's probably corrosion somewhere or just a miscellaneous error that won't go away until something burns out. Ipdm connectors, abs connectors, things like that

My Z has had this code ever since I installed the z1 stainless brake lines and also switched over to motul rbf 600 brake fluid. I noticed my tpms light flashing and scanned it and it gave me this code. Not sure if itís related or if thatís just because I had the battery disconnected for awhile while bleeding the brakes (iíve had issues with tpms before but never cared to check it out). Anyone had this issue after changing brake fluid or lines? Thanks!
