Service 4wd light intermittent/ Dodge 2500 Power Wagon 5.7 Hemi.
Service 4wd light comes on on occasion.
goes out after about 2 min; into morning warm up.
came on yesterday for the whole drive home from work, about 60 mile..
Then did not come again until about 30 miles into this mornings commute. Then went out about 20 mi; later.
When it's on, the rear lock light on the switch flashes.
Normally in normal drive mode both the rear and rear/front lock will flash if set to that point but not in 4wd and acually set to lock.
But when service 4wd light is on and rear lock is flashing, if I set it to rear/front lock it does nothing, no flashing.
I was told 4wd module or transfercase 4wd motor/solenoid???.
yes/no?. Or something else. I notice no issues in normal driving mode.

So my low tire pressure warning goes off because it says the right front tire is low. ... It should reset, it may take a cycle or two but unless you need a new sensor it should be ok. ... It was automatic on my truck and it's a 2010.
ABS and Brake warning lights intermittent may be caused by a failing wheel speed sensor(ABS Sensor) and /or its connector. You may have one on each wheel hub(4WD) or if 2WD, a sensor may be on the rear axle differential center.
It's probably still a problem with the ignition control module/coil, with a circuit in or attached to it heating up as the engine warms, and then the circuit opens when stopped and it starts to cool. As soon as the engine sufficiently cools off, the circuit would revert to a good connection. I would carefully check the connectors and wiring on both sides of the module, and then possibly trying another module.
Well it could be the selector switch, but I doubt it. Generally, the service light means something is not working that the computer controls. Solenoids and valves are a couple of possibilities. The transfer case is shifted by solenoids commanded by the body computer based on the switch position on the dash. You should be able to have a shop scan the body computer for trouble codes and proceed from there. A basic code reader may not access the body computer.
4 wheel drive service try un hooking the battery for 5 min and see if that clears if not go down to auto zone use there computer to clear it the computer wants you to change the gear lube in the front rear and rear rear it wouldn't hurt to check the level in the transfer case
MIne will do that only when I'm switching my 4WD to 4low or 4hi, or back to 2hi AND the TB has good traction, ie pavement or rock OR the tires are cranked to one direction. After my wheels are straight, I just turn the engine off, and turn it back on, then the light goes off. Mine won't do that if I'm in mud, snow, or dirt where there's no traction. My guess is that it may be binding when the traction is good, therefore, I shouldn't be in 4WD. Anyway, my 2cents and I don't think you have to worry about it.
