All D2s have TC. If there is no light, then it has been disabled - perhaps to hide a fault. Do the ABS and Hill descent (HDC) lights come on with the ignition?
Not all D2s had the diff lock lever, although your model year will have the mechanism in the transfer box. You just need to fit the right kind of lever - one from a D1 can be modified to fit, or there are a couple of people supplying after market levers. Or you could go genuine.
