Did this light came ON when you unplugged the car battery or after you unplugged the radio/How actually this light came ON.Actually it requires a radio code to make this light OFF.Its a 4 digit radio code.Insert that and the light will go OFF. If you dont have code then the only possible thing to get the radio reset or get the code from dealer.Both can be done at dealer place. There are many users facing this same problem. The password/code can only be retrieved from service center or from the dealer of the unit. Because at the back of the unit there is a serial number mentioned and the password/code only can be retrieved from the serial number. Each and every device/unit has its own serial number so one serial number code/password will not work with other serial number code password. The service center or the dealer has the list of code for the serial number so as soon as you provide the serial number he will get the password/code
Retrieved for you through the list. This will help.
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

You need to go to the dealer and get the unlock code after this problem occurs. There's no way around it. They do not publish codes online for people to do it for free.

Hope this helps.

You've accidently triggered the security system. You need to lock the vehicle using the remote on your key then unlock it again using the remote. If you don't have the remote you'll have to contact a dealer in order to reset the security system.

SOURCE: 01 Chevy Silverado 4 X 4 not working. 4WD light

Having the same exact problem but with my 1999 escalade. Thought it was the actuator bought a new one installed it transfer case would engage but front end wouldnt lock. Took it out of housing left it plugged in got a friend to go through all the 4wd for me and the plunger never moved out the actuator. Checked my wiring harness which is a four prong ann it had one hot prong like it is suppose to. Traced wires even replaced dash switch same problem. Taking it to local dealership tom to have it checked for codes. I was told it could be the transfercase actuator even though its workin that actuator is what sends power to the front to engage the actuator to lock the differential.
