Had the Tech2 out to pull DTCs to see if that HVAC actuator code came back and I got this one concerning the object detection modual.

I usually don't have any problems with it, but sometimes when on the highway and in the left lane and I go by some guardrail it will go on and not turn off for a while. I'll usually use the DIC and disable the Blindspot warning so it goes off, then re-enable it.

Think the sensor needs replacing? 89119bceb71bf0ac4d69c29d324c5d64.jpg

I would try cleaning it if they get muddy or dirty they may not work properly, maybe clean and check the harness, then go back in the tech2 clear the code, run a test and see if it stays gone or remains an active code, if it stay gone you are good just check it again later down the road

Figured I would check out my charging system since putting in the new batteries and running both grounds to the RVC a couple weeks ago, appears everything is working normal again no negative amps and the economy mode isn't kicking on when it shouldn't like it was with my old batteries, turned everything on and it has nice positive amps, I guess the batteries must have been bad even though they tested good and/or running both grounds to the RVC helps. Either way seems to be ok now, cleaned the throttle body and MAF and reset the transmission fluid life since it was just flushed and they didn't reset it, it was on 6%
