So first time ever I’ve had the engine light come on. Of course it’s while I’m cruising through the BC mountains.

I did the ignition 3 times thing and got the following codes:
12
14
42
21
17

All my gauges are perfectly fine. Temps and all. I looked these errors up and all seems voltage related. I pulled over, all seemed fine. Turned it on and off a couple time. Ran no differently. Really didn’t expect to get more than one error code but maybe it’s a domino effect?

I think it will be ok driving 3 hours back home tomorrow before getting it checked out. I did recently install some rock lights (they were free 🤷‍♂️) so I disconnected that wiring just in case.

If anyone has experience or advice please let me know!
