Cruise Control issues

[butch1581]

I have the "cruise control issue" It will work fine for a while, then it will start only working at certain speeds. (Like only above 65mph, or only below 60mph) It seems to vary a lot. I tried disconecting the battery overnight and it did not fix it. I tried loading all three "canned" tunes and same issue on all. Cruise works fine with the stock tune? any thoughts? I did not have this issue when I had Crom 9r06. Any help would be great

Calibration ID:
PCM: 56029207AK
TCM: 56029224AF

Thanks

has anyone else had this issue, where disconnecting the battery did not fix it?

Any chance you can post your VIN for me?

Thank you, we are looking into it.

Thanks Mike, I love the tuner other than this issue, so I hope I can get my cruise back soon. Thanks again.

Im having the same problem,the Cruise Control will only work up to about 65mph and then it clicks off.

I have the same issue on a 2004 ram,kicks out @ 65mph but you can turn it back on
below 65mph and it works perfectly.
If you go back in my posts you will see that I have had this problem
since the beta test file.other than that no complaints.
Thanks Mike

Strange, mine is just the opposite, it only works above 65mph....

so get this......
Loaded the stock tune back into the truck.....still no cruise control.

Brought it to the dealership to have them look at it, and they told me it was the front left wheel speed sensor. They had to order the part, so I picked up my truck. The sensor has NOT been replaced yet, but my cruise works fine all the time now. I loaded the 91 tun back into the truck, and it is still working fine. I called the dealer and told them I don't want the part replaced yet, because its working fine. (I have a $100 deductable on my warranty) I assume the dealer "reset" or did something to the PCM. Is whatever they did different from diisconnecting the battery?

Is there a chance they just "flashed" the pcm or whatever and that fixed it, and the wheel speed sensor was just a cover up part so they could get their money from the warranty company? Hopefully this is the end of this, otherwise it will go back in for the sensor repalcement. ($150 from autozone, so I will let them do it for $100)

There, I am done, sorry it was so long.

interesting...

Any news on this subject?
Going on a long trip shortly and it would be nice
to have cruise above 65mph.
Thanks Mike

My cruise stopped working over the weekend again, It goes in Wednesday for front wheel speed sensor replacement, hopefully that is the problem. I hope its not a diablo problem.

I have the same issue for about 3 months. I have the 09t08 crom loaded but it doesnt sound like the 09r08 will work any better. Could it have anything to do with changing tire sizes on the unit?

[butch1581]

so far so good on mine. I had the wheel speed sensor replaced, and its working fine now. As for now, I can say that Diablo was not the problem. Bring it to a shop that can hook it up. They told me that the speed sensor was reading 0Volts when they took it for a ride. Sensor is about $150 from auto store, if you do nt have a warranty left.
