Not sure what's involved in the 4wd service
No , it's not a timer light for general service . There is a DTC causing that to come up . Get the code scanned somewhere capable of reading the ABS and TCM codes . You can try the key dance (search key dance ) to display OBD codes , but that generally doesn't show you the service 4wd DTC's . I think everyone should know how to to that anyways though .
