Between a 2019 and 2020 bodies? I’m looking at some painted wheel well arches and wondering if they are the same wheel openings.

In 2019 GM made both the old (K2) and new (T1) body styles. You would need to confirm which one the accessories are made for because nothing interchanges between the two.

    • We tested the sleep mode with an ammeter in series with the negative battery terminal - 30amp fused - so we do know the actual shutdown and non-shutdown current draws and timing of the shutdown sequence.  We just have no protocol information to determine what module is issuing the network keep alive.  
    • TrueBlue...Even if you don't have that info stuff displayed, If Mr. Computer thinks there's something you should know about, it will pop up a warning message no matter what else is being displayed. I keep the speedometer displayed all the time, yet the brake pad message pops up anyway.
    • BTW, the 11.5amp draw is all the usual systems active - it's not a single draw - that's the "we're all awake" state of the vehicle - forinstance if the power steps are actuated, the draw will spike to 22amps for that operation.  when the battery is disconnected and then reconnected, the vehicle shuts down that one time only - and we see a 10-15minute progression down 11.5  10.5  9. 8 6. 5. 1.6... 500ma... and then off to sleep at 40 milliamp... as expected.  So we know it's a module that is simply refusing to allow the SDGM to proceed to the sleep state.  We do NOT think it is the telematics VIM module - since we already duplicated the problem with the "VIM bypass" solution installed (we reverted that since it also disables the gmc app - but it does not appear that the telematics system is the culprit).  We've replaced the rear heater control module, tested without the wireless charger, and the other modules on CAN Bus 5 - but still something is keeping us awake and removing X2 from SDGM allows sleep to proceed.  We cannot diagnose from OBD since OBD drops off at about the 9volt level in sleep mode and we can't communicate with the vehicle - also we can't trace the SDGM internal packets from the OBD side - we have Autel Ultra.   Any ideas on why disconnecting X2 would allow sleep to proceed appreciated.  This is no longer a repair situation - this vehicie is simply unusable in this condition and NOBODY at GMC Dealer can even understand what it is doing.  This is crazy.  We made these systems too complex and now we're paying the price.
    • Did this ever get solved?   I'm chasing 2021 Yukon Denali electrical issues - vehicle will not enter sleep mode - we can disconnect and reconnect the battery and it will sleep - but that's likely because we powered down whatever module doesn't correctly sleep.  once we start/accessory the vehicle and turn off, it will stay at 11.5 amp draw with something keeping the SDGM alive - it appears to be activity on the X2 segment, specifically CAN FD Bus 5 - but we don't know which device and we think we've already isolated all of the devices on that segment - so what keeps the BCM and/or the SDGM alive is unknown.   I don't yet have a packet trace from CAN 5 (and since this Global B we might not get much info from it) - but the vehicle has been down for 8 weeks and previously GMC Dealer was unable to resolve "kills battery" issues with this particular vehicle - so I'm at a loss - it seems to be beyond local repair capabilities - and the number of "telematics keeps vehicle from sleeping" posts indicates this whole architecture has major issues - I hate to say it, but we might have to install a battery cutoff switch on the front grill - one of those red boat switches - to turn off the vehicle.;)  Any pointers appreciated;)  I just bought a CAN FD interface and I'm planning to try Savvycan and Peak Can SW to triage this further.
    • Have had this truck for 7 years and it has 135,000 km on it. Have had no issues with it. Had 70,000 km when I bought it so I average about 9300km/year. The other day I started it to leave grocery store and felt a bad miss as I was pulling out of my stall. Rolled down window and heard the clatter. Limped it home about 1 mile and investigated further. Cylinder 6 misfire,  check engine light flashing and I believe traction control light on. The flattering gave it away in my mind. I did try swapping plug, coil and wire from 6 to 4 hoping the moss would move to 4 but no luck. Also compression dropped to 120lb when cylinder 1 has over 200lbs. Called tow truck to tow to local GM dealer. Failed lifter and 1 bent pushrod. Dealer changing lifters and pushrods on 2,4,6,8 and also VLOM. Think it may be time to get rid of this truck when I pick it back up from dealer. Dealer told me they do about 2 of these repairs every month.
