2012 Winnebago Access Premier, Ford F450 V10

Question

Hello everyoneHope everyone is enjoying the RV life.Last week while driving home (Oregon) from a 4 days of Salmon fishing, my cruise control and tow haul systems quit working.  Everything else seems to be working and I drove it the rest of the way home without incident.  With neither system working I do get a dash indicator light for the tow haul.  Also both systems quit at the same time and the wrench icon showed up on screen.I'm checking fuses now but suspect that's not the problem.  Fuses is about all I'm capable of fixing.Any and all help, ideas, guesses, thoughts welcomed.  Leaving for Arizona next month, so has to be fixed.

Wrench is NOT the same as check engine !Most big auto parts stores will scan for codes for FREE.  My SWAG is a bad wheel speed sensor.

Wrench icon indicates “Limp Mode”.  Some capability has been disabled but you are still able to limp along.  Good thing to carry a Scan Guage II in your toolbox on trips to do basic diagnostics.  Plugs into the diagnostic port below the dash at the steering column.

I checked fuses &amp; relays that I figured might be the problem.#38 Relay Electronic Control Module#52 10amp Electronic Control Module/transmission Control Module#72 10amp electronic Control Module/Keep alive powerAll testing ok.Codes found with my reader:P0138  02 (H02-12) check high volt  (B1, S2)P2270 02k Sensor stuck lean (B1, S2)So this seems to tell me: Bank 1  Sensor 2 is alarming or is bad?Wonder where it's located? on the exhaust or header pipe? or ??I cleared the alarms and will give a test drive when weather allows.  See what codes reappear.Thanks for helping.

How do you "clear" the codes and ... don't/won't the codes occur again soon if you don't do any repairs?Also once one uses a reader, where does one look to see what the codes mean?  Is this included in documentation that comes with the reader?

I put a Banks exhaust/intake on my rig. It came with a Banks code reader.

The "reader" has the function to clear a code or all codes. Some codes can be transient in nature, nice to know if it's permanent code (problem is continuing).
Codes can be research online or use a OBD II code book. It can also allow some changes in the program. I've never use it for that .......... yet. I believe there is a history in the truck's computer but I've never had the equipment to access it.

Not sure how to post a photo?
