vtm-4 light went on car stalled what does it mean

If a malfunction related indicator came on (your VTM-4 light could also come on due to locked in engagement of the 4 wheel drive system), you will have information stored in memory of the affected modules indicating something that malfunctioned. Testing needs to be performed to find out what codes may be set, and then further what those codes mean. The noise is something that must be heard by a trained ear that can help diagnose the concern.
