Service All-Wheel Drive Light

The service all-wheel drive light comes on to
indicate that there may be a problem with the drive
system and service is required. Malfunctions
can be indicated by the system before any problem
is apparent, which may prevent serious damage
to the vehicle. This system is also designed
to assist your GM dealer in correctly diagnosing a
malfunction.
