My new Hell, steering rack replacement/reflash issues

 Let me start buy saying GM is really crapping on people by not doing a recall on these racks. 

  I started with a torque angle steering sensore issue. This sensor being (built into) the rack it was "eat it" and do the whole rack. This is when I found out it is IMPOSIBLE to purchase a new r&p for these trucks. IF you can get one it is a reman. (And for anyone who looks or has looked in places like parts geek etc. They have one listed as new from Detroit Axle. IT IS A REMAN! Ask me how I know.) This all being said there is a long list (about 15) of part numbers of racks that have been succeeded because they will not flash properly to the vehicle. The newest is not even available from Detroit yet.

 

The shop that flashed mine first was able to flash everything BUT the torque angle sensor. I then purchased the short harness from GM that goes from that sensor to the motor side of the rack (it did look a little sketch from the get go). With the new harnes it now flashes, but the steering angle sensor is throwing a code. Steering works again but now the you can read the steering angle sensor through the rack but not through the PCM. 

I still have all the same service steering system warnings etc except the PS works now. I'm basically at $800 with this shop and they won't do anything else. They will only install a junkyard rack and flash it from here.

 

Has anyone on here run into a similar issue with flashing a rack to their vehicle, or does anyone have any idea of what I should try next? Possible PCM issue?

I'm curious on what year & model you have, as well as miles on it when u started having this issue. Did I miss this information somewhere?

Nope you didn't sorry. It's a 2015 sierra Z71. Has 93k miles. The sensor issue started started about a year ago slowly with a message here and there. Then it progressed to the point where it came on everytime I drove it. The the PS actually started to go out while driving. It would be back on after I parked it and started to drive again. Then it was basically just out all the time and would magically come back for a short time here and there when I had to drive it while searching for a rack.

Your year truck had issues with poor or bad grounds. Search YouTube for this. Not saying it wasn't your steering angle sensor but there's lots of videos showing the steering (and other things) affected by a bad ground, specifically on the left dash. Just a long shot here, but start with the easy fixes 1st, then the harder & more expensive ones. I did the ground update even as a preventive maintenance upgrade after seeing all the bad ground issues on YouTube.  Good luck & hope you get it sorted out.

Thanks. I'll look into it. From the start the original issue was the torque position steering sensor. In doing this process I've come to realize that it was possibly the harness P# 38021685 the whole time (which I replaced). I have my factory rack still and I'm half tempted to plug it up with the new harness and see what happens. In theory it will still be flashed to the truck. If I could justify the cost of a new J-pass box, I would have one in the Mail already!

      OCI, not when but why?

      By Atlas · Posted

      In most areas of the country, wages have trailed CPI increases over time (let's say, since the 70's) and things like housing, energy, and food have vastly outpaced wages on the whole. Can't ignore that, it's very real.   That isn't to say there aren't ways to live in ways that mitigate some of that, including moving to cheaper areas of the country. In KNut's neck of the world, median housing prices in "nearby" Dallas are more like $500k. If you're raising a family and young in a successful career, your economic opportunities are probably going to be better living closer to Dallas than Cornhole. A 3 hour (6+ round trip) daily commute probably isn't tolerable for most folks. Grumpy mentioned economic migration; but we've seen what happens when people populate and grow an area. It becomes more expensive when economic opportunities come to roost.   One thing different now from back in the 70's is our quality and standard of living has changed. Healthcare is light years better, for example. But it's also much more expensive. And we have communication and information/tech tools that folks in the 70's could never imagine, and they're accessible to people of just about all incomes. Cars are light years safer, faster, and filled with tech advances. Homes are larger, more energy-efficient, and more luxurious on the whole, from starter homes to luxury homes.   Seattle was once affordable. My folks came here in the 70's with a lot of other people from California looking to escape uncontrolled sprawl, smog, and rising prices in the Bay Area. Seattle and the surrounding area has grown considerably; The home they bought for, I think it was $70k or $80k in the late 70's is now worth $1.2M today. The same house.   So while there have been obvious boosts in some areas of quality and standard of living, regarding opportunity, that's a bit more nuanced. It's really not possible for young people to get started in similar situations in areas of the country that have become "HCOL" (high cost of living). There are many more areas than before, which is to say they exclude younger workers or make their lives significantly harder. They have to commute farther and longer to afford to live in the area. They have to take outsized risk, take on more debt, significantly delay family planning. Or, they could move somewhere cheaper, but there's usually a loss of economic opportunity that comes with that. Even for the same job, it may pay a lot less in a LCOL.   What I don't like are Boomers with phones thinking they have all the answers and outright saying that if people stopped paying for their cell phone that they'd be rich. It's as stupid and misguided as people who think they'd only be rich if taxes weren't so high. Sorry guys, Elon proved you wrong on that one, I guess you're just lazy and blaming your own situation for the reason you're not wealthy. Mobile communication is basically an expectation in a modern society and workforce and it's often cheaper than having a copper landline these days, so... What's your point?

      Ac not keeping up

      By asilverblazer · Posted

      My 2008 started exhibiting similar symptoms, wasn't 'cold' enough. I went through a pretty extensive diagnostic process for a DIY'er with limited OBD access. System evacuation and recharge included.   Noticed one day the passenger side was cold (I'm never over there so took awhile to notice).   Pulled the drivers side blend door actuator out, disassembled it and cleaned it out. Put it back in and did some kind of reset and it fixed the problem.   Long story short, it wasn't the A/C system at fault, the blend door wasn't moving to full cold position.

      summer road trips in the 2026 2500HD

      By c4racer2 · Posted

      Just got in two back to back road trips of about 700 miles each with my new 2026 2500HD trail boss.  Really nice highway cruiser. Two very different trips - both loaded with gear for my band. First trip was to Durango for an event with Indian Motorcycle - saw some really nice bikes while out there! All mountain driving on back country highways - very pretty scenery - lots of hills along the way including a crazy pass that went up to 11,000 feet! Overall MPG for that trip was 15, speeds were typically 60-70 range depending on road.   This past weekend was into rural Nebraska, so mostly fast interstate (76 and 80) with some fast 2 lane getting to / from the final destination outside of North Platt. Speeds mostly ~80.  Also mostly flat although somehow dropped from 5K to 3K feet and then back up getting back into CO - didn't really notice it was subtle probably over a long distance. Overall MPG for the trip was 14.   Truck is still barely broken in - just got past 2K miles on the second trip. We survived some torrential thunderstorms in NE on Sat. night - especially driving to the hotel after the gig at 1AM.  Truck didn't skip a beat - I think the weight of these HD trucks really reduces the hydroplane chances.   All good - made it back to Denver area mid day on Sunday for fathers day.   I did a quick calculation to compare MPG and overall trip cost to my previous truck, a 2018 Colorado V6.  From previous experience I would have expected to see a 4mpg improvement on both trips.  Based on current gas prices which are starting to come down but still $0.75 to $1 higher than they should be based on barrel pricing, each trip was about $40 more.  Really not much of a concern in the grand scheme of things I must say.
