I have an '18 2500 gasser and the newest Haynes manual is for 2015-2016 2500 as well as 14-16 1500.

 

Is there a better manual available specifically for the 2500?

I've often thought about an ALLDATA DIY subscription for this but never tried it.

Haynes manuals are excellent for starting a campfire.  Nice thick paper, holds being crumpled well, stays where you put it and burns nicely.

 

For diagnosing and fixing your truck, either get a subscription to the full service manual (FSM) at various web sites (alldatadiy.com is one) or get the paper version (helminc.com, amazon, ebay).

 

The haynes manual is maybe 200 pages (being VERY generous), and a lot of it is just generic info that is the same in every book they publish.

The full-service manual for my '04 Sierra is 5 volumes of 1000+ pages each (it does cover 1500/25003500 & all the gas and diesel engines in the pickups).

 

The paper version is available from helm, so alldatadiy should also have it online, but I would double-check with them before paying for a subscription, as it takes a year or two before the FSM becomes available.

The 2018 manuals are now available at Helm (they weren't out the last time I looked)

Helm distributes the factory manuals for several manufacturers

 

https://www.helminc.com/helm/product2.asp?Make=GMC&Model=SIER&Year=2018&Category=1&class_2=GMC&mk=GMC&yr=2018&md=Sierra&dt=Shop%2FService+Information&module=&from=result&Style=helm&Sku=GMT18CKPU&itemtype=N 

 

Same set does Denali, Sierra and Silverado.

They are pricey but very complete -- last set I had was multiple manuals that filled about 2 ft on the shelf and covered 15/25/35

That looks pretty decent for $20 for a year.

      Ac not keeping up

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
