Which fuse for ACC/FCW system?

[WilburNJ]

Hi folks,

I'm hoping someone can help me save a trip to the dealer. A warning light and message on my 2020 1500 Laramie suddenly says "ACC/FCW Unavailable." In addition, I have additional messages that say: "ParkSense Temporaily Unavailable", "LaneSense unavailable", "Active ParkSense Unavailable" and "Service Electronic Stability Control".

I unplugged the 12v battery for a good hour or so to allow a reset, but that didn't help. I read that driving at highway speed might reset these systems, so tried that but the error messages are still there.

I can't tell from the descriptions in the manual if there is a fuse that governs all of these systems. Does anyone know?

Thanks,

Will

ESP is F26 and F29, under the hood. The others are not listed under fuses, so module controlled. I doubt it's a fuse. Check all grounds, there are 30, and cause problems, or wiring. Even your battery going bad, can cause odd warnings. If it's original, replace it.

If you are still under the warranty period, going to the dealer is the best solution. Before you go through a dealer visit hassel, have the DTC codes read which could lead to the root cause saving you a visit.
