Hello, not sure if there is a thread about this already but i was unable to find anything, i have a 2015 tahoe ppv, and the autolamp feature is not working, i have looked at the menus available in the car but no luck, does anyone know how to turn this feature on? Also does anyone know if theres a GM program similar to forescan to configure this tahoe? Thanks in advance

It’s very possible your daylight sensor on the dash has been bypassed. They install a resistor in line so the car thinks it’s always sunny.

I did this on my van and learned it from someone who outfits ppv’s. (So they said)

Were you able to see the resistor by removing the sensor? Or was it buried behind the dash? Thanks for your comment i will try this tomorrow

Really depends how it was installed if anything.. The sensor is on its own circuit that runs back to the BCM I think. So you could splice the wire anywhere along the way that’s easily accessible.

I spliced mine directly into the sensor. So the internals of the sensor are destroyed.
