2011 Ram 1500 Service 4 wheel drive code P0593

Model: 2014 Ram 1500 Fault Code: P0593 Posted: 2018-03-22 17:57

I just had 2 TPMS valves changed. Now I get a CHeck 4wheel Drive system light. I also get a code of P-0593. When I switch between 2 and 4 wheel drive some times the 4 wheel drive light comes on and sometimes it does not. Also it appears that although it says 4 wheel drive it is not in 4WD. ANy ideas thanks in advance....

P0593-SPEED CONTROL SWITCH 2 CIRCUIT HIGH first thoughts , Any other codes or issues? You are using a good scanner - Able to show all codes? horn OK? Cruise control OK? NO dash lights? such as ABS or SRS (airbag)? Vehicle is STOCK ?

Veh stock, no other codes, horn, cruise works no other lights. Before it happened I went through a car wash. Veh is stock except custom rims. Never had any problems with truck.....
