Re: Warning lights
Yes, my cruise control normally works, but i never tried to put it ON when the ABS/TCS light was ON.
Before i erased the code, i checked the ABS/TCS snapshot from the Tech 2 and found that the RR wheel sensor speed is 0km while the 3 sensors at 55km.
I first check the wiring from the RR wheel sensor to the EBCM and found no problem as per GM service manual flowchart.
I just changed the RR wheel sensor, road test with the Tech 2 and all wheel sensors reading are the same.
It's all good for now.
