Ash accumulator reset. SPN247. Which portable reader....

can reset the check engine?
2015 Coronado (factory, not glider) DD16. In my No databus communication thread that has no replies, I explained the issue when driving in rain. I finally believe I narrowed it down to the ACM module water infiltration as it sits right in the water path, behind the left front tire.
Installed new, not rebuilt ACM programmed to my VIN and was greeted to this.




Checked starter, it started right up. Let the air build and while building, the solid engine light, and the red stop engine light went out and the def gauge went to normal. So self clearing EEC.
Googled the check engine code, which from my Nexus reader said spn247, there was a possibility that a drive would reset it. Nope.
So same reason that I bought my own Robinair RRR AC machine, I'm not scheduling another stupid expensive visit to the dealer. I really don't want the OTR as it requires a subscription. What other portable reader can clear the SPN247 code related to the replacement of the ACM?

 

I grew up in a 1962 KW K100. 280 Cummins, 5'n4, and if you are old enough, you'll remember "center point steering". But I'll be honest, as much as I too like the simplicity of the older trucks with no emissions, I don't wanna go back. I have become very attached to my cell phone and the internet. I learned some time back that everything is relative.

 

Pretty sure this is just the ACM code. Recorded mileage at the ECM does not match the new ACM. I'll give the battery disconnect a try this morning. There are a few bidirectional scanners that seem to get good reviews on some of the shop channels I watch.

 

What's a price range? Not looking for exact money, just a range.

 

The nextiq is not that bad really. It seems spendy for a little box that contains 3 dollars worth of chinesium, but like you say, the savings vs. time in the dealer's shop.
