This answer was rated:

2009 Sierra 5.3L has Service Stabilitrak & Service Traction Control lights on and truck not getting up to full speed. What is the problem & is it OK to continue driving? Currently stranded on highway on Thanksgiving in northern MI

Gm Tech (Cam) :

Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.CAn you find the stability disable button?

Customer: I'm relaying message for sister stranded on road with no Internet. Not sure if she can find this button.
Customer: She has tried pushing traction control button
Gm Tech (Cam) :

OK, then is the /ABS light on as well?

Customer: Top speed is 45 mph
Customer: No
Gm Tech (Cam) :

OK, so the system thinks there is a slipping wheel. Unplug one of the front wheel speed sensors and see if you can disable that and get full speed again.

Customer: Previously a spark plug light was on. Dealership checked & said it was electronic glitch & they couldn't get it to turn off. That was last week.
Gm Tech (Cam) :

Ok, try the plug for a sensor now and see if the makes the ABS come on and disable that.

Customer: She is driving now at 45 mph. Will arrive here in 45 min. Will try this here rather than on the road. Thank you.
Gm Tech (Cam) :

Ok, if it does work, and know that the ABS light will come on, then it needs repairs to the traction system or one of the sensors.

Customer: Ok. Thanks. Happy Thanksgiving.
Gm Tech (Cam) :

You as well.
