2002 rubicon. When I shift into drive the D or ESP the indicator does not come on. The bike will drive but not shift and will not go into ESP. But if I go into low everything works great. Some time's the D and ESP modes will work. NEED HELP

 

Not a lot of detail in your decription. You really need a shop manual to use the self diagnostics and troubleshoot electrical on that model. About all you can do without it is check your connectors to make sure they are full plugged in and locked. particularily the ones underneath the right plastic cover, the couplers to the ecm underneath the rear rack, and the ones in front of the engine.
