I rewarded Red's good behavior with a minor detail today. Wash & wax, engine bay wipe down, and interior wipe down/vacuum.
Added these, courtesy of SpookX5, all the way from the Netherlands. Gotta rep the Outpost. Thanks for having these made Jordi, they were worth the wait.
After completing all of that I decided to have some more fun with the coding setup. I re-coded the LCM to play nice with all the LEDs on the truck as the cold and hot monitoring codings had been reset when the ZCS was changed. This took care of some errors being reported in that module.
Then I decided to play with INPA and see if I could diagnose the ALC system that hasn't worked in years. Only the right side headlight would function as adaptive lighting. The left was fixed and actually had to be jumped just to activate the low beam (I have a thread on that somewhere). This is necessary because the LWR (main control module that runs ALC) disables the headlight when it detects a fault. I assume to avoid blinding oncoming traffic? I found a setting in the module that can be turned off to defeat this fail safe but I left it on.
So I ran through some of the activations, live data, etc INPA offers and found all the motors were good in both headlights. I could not see any real differences in what the headlights were reporting one side vs. the other excepting what the ride height sensors were reporting. I did find a counter (offset counter I think?) and it had a reset option. So I went ahead and reset it. I now have 100% functioning ALC again. I even managed to get the wife excited with that one.
Because the system hadn't worked in so long she just figured it never would again. Never count an idiot with a laptop out!
Thinking about it though, I'm wondering if the offset with the height sensors were playing havoc with the EHCII system as well? I seem to remember reading a couple threads here where counters needed to be reset after servicing certain components. That's just a guess, but it makes sense to my tired brain.
So all in all, a pretty productive day in the garage. Now I'm beat.
