Question about 2004 Pontiac Grand Prix
I have similar messages on my cars message center. The message center says service traction control and ABS system. I checked the codes on my OBD2 reader and no codes are stored on the computers memory. Makes sence since the check engine light is not on. It would be nice to know which sensor it is but since there is no code it's hard to tell. What can I do? Buy a sensor and go around and try each one?
If your trac and abs are both on. the problem could be a wheel speed sensor.
on some GM cars this sensor is built into the vehichles hub unit. making the bering and sensor one sealed unit. cheap hub units can be gotten (under 100 bucks) at autozone

If the system fails to turn on or activate, the StabiliTrak®
light along with one of the following messages will be
displayed on the Driver Information Center (DIC):
TRACTION CONTROL OFF, SERVICE TRACTION
CONTROL, SERVICE STABILITRAK. If you see these
conditions, turn the vehicle off, wait 15 seconds, and then
turn it back on again to reset the system. If any of these
messages still appear on the Driver Information Center
(DIC), your vehicle should be taken in for service.
