I know this has been beat to death, but it still wasn't straight forward for me. I have a 2020 Power Wagon. I have a few notes (as a summary) and a question at the end. The CAN blocks were tricky to access on my 2020. They are behind the light switch. You can take off the kick plate with 2 7mm screws then pull. Take off the light switch assembly just by pulling hard on that sucker. You can take the plate under the light switch off too by pulling. I was able to get the CAN connectors in OK. But no way getting them out without taking the CAN blocks off their mounting location. Luckily they clip in/out easily. Once you loosen them, you can get a small screwdriver in there to remove the catch pins. Trying to clear some codes, I disconnected my battery. This completely wiped out all apps. So, my backup camera, air conditioner and satellite radio access icon were gone. I read they will come back on their own after the truck re-loads them. That's what happened! About 3 hours later, after much panic. I purchased the ODB Link MX+, AlfaODB app for my Android phone, and the Kaodtech bypass cable. Mike at Kaodtech was a HUGE help with my stupid questions trying to figure out where the CAN blocks were located. Once all hooked up, I followed the instructions on page 1 of this LOOOOONNNNNNGGGGGG thread. And overall it worked. It took about 6 times to get my circumference dialed in for my 35'. Ended up at 2688 mm. Now for the Question No matter what I do, I still get a C006A fault (access accelerator sensor) and cannot clear it. When I turn on the engine, both cruise controls are disabled (adaptive and regular) and it says the Stability control has been disabled and needs service. It also says the trailer brake system needs service. I've performed the resets on page 1 of this tread probably 30 times: Static ECU initialization and clear rolls information. I've done them with push start recycle and without. I've waited 5-10 minutes between cycling with no luck. I've tried other resets too like ECU. I disconnected the battery for 30 minutes: Still no luck. I've stood on my head on a full moon. No luck. I ended up taking it to the dealership today. they can't get to it for a week. Which is what they told me after a stern lecture (as I expected). Any additional help/thoughts would be greatly appreciated!
