Well the title says it, I know it's been discussed before, I manage to fix the Cruise Control issue was due to my 3rd brake light swap with cheap LED's I bought off ebay (never gonna do that again) Anyways I went back to stock bulbs for the 3rd brake and fixed the cruise control.

But my SVC monitor is just not working at all, this was also caused by those LED lights I bought, none of the sensors are bad and one was recently replaced back in January. There is no reading of tire pressure from all four tires, I tried airing out my tires to reset the sensors but nothing.

 

i believe there is a pcm for the tire monitors.. probably in the trunk

 

or just go to a dealership and have them relearn the sensors

 

Its Either That ^^^ or the Sensors need to be replaced.

 

maybe your right I bet when I switched those bulbs it caused a reset on the sensors. How much would the dealership charged for them to be relearned?

 

shouldnt be too much, down here the quick lube guys at dealerships always take care of it
(no charge)

 

The LGM controls the the rear hatch functions (reports to BCM on hatch ajar message / dome light) it is also the reciever for the keyless entry and the reciever for the tire pressure sensors. With all those things acting up all at once, I'd start my testing at the LGM.
