Bad ground clamp at battery that LOOKS fine - possible source of TIPM/DTC problems
So today I was working on my 2011 JKU and noticed that the OEM ground clamp was loose. It looks like it's fully clamped, but when you push on it, it moves easily. This may be the reason I've had intermittent DTCs and faulty TIPM-like symptoms. The video shows what I'm talking about. The pic shows how the clamp had burn marks from not making a good connection.

are you running your stock battery still? I swapped to an Optima and the clamps fit a little tighter.

No, I'm running a Sears Platinum Marine battery (AGM). I found a new clamp for the ground post and it's tight now. Not sure what the deal is with the OEM clamp.
