Good morning. Tried searching but didn't find anything. 2006 GP 3.8 supercharged. If the temp is below 45F the ABS and Traction Control work fine - no issues. Above 50F I can be driving down the highway, 65-70 MPH, smooth road (for Pennsylvania) and the Traction Control and ABS service lights will alert on the central panel and light up on the dash. I've cleaned the connections to the ABS controller. This started after the transmission was replaced last spring (carrier bearing in the differential failed - interesting sound). All connections seem OK (disconnected, hit 'em with contact cleaner, dab of dialectric grease and re-assembled). Both front wheel bearings were replaced last April, with new toner wheels. Lower control arms replace a month ago, but that can't have anything to do with it. My issue is that the only factor seems to be ambient temperature. One aside, from time to time I do get an over-voltage (15+V) and the 'charging system failed' message (I assume this is a ground and will be digging into it this weekend) but there doesn't seem to be a correlation between the two events. Ideas? To be honest, I'm an old motorhead and am far more comfortable with points, a timing light, dwell meter and carbs (with a sync gauge for mutliples) than I am with OBD2 warnings - but I figure it's time to learn! Thanks in advance.
