Is this the ASI you are speaking of? I keep this as a reminder of the debacle I went thru with them back in 09 or 10. The first one tripped 606 code and the truck would not run. They kept my core charge and it took 6 additional weeks for them to send me a replacement. It only lasted a year before it left me stranded on the side of the road. Cruise never worked on it either.

 

Yes that would be the same ASI. I will steer clear of them.

ECM was shipped to ACS yesterday.

 

Got the truck home on the ECM from the 2001. In the meantime will be testing for AC noise and doing the ground mod.

 

I'll report back once my repaired ECM is returned. The OCD in me stamped the case of my ECM with the last four of my VIN to see if I get my ECM back or one that was already repaired.

[gipperkid]

So I picked up an Innova 3320 since my Craftsman multimeter was too basic.

 

Started the truck cold and the grid heaters were kicking on and off. Both batteries were at 14.24 volts at idle.

 

For AC noise I got intermittent readings of .017 to .019 and then I would get .048 to .051. I'm not sure why the readings would fluctuate. But with those numbers I'm assuming the alternator took out the ECM.

Readings get higher when the grids pull a load on the alternator. If written correctly your readings are very acceptable. Not many see as low as .017.

It was definitely .017 to .019. I guess my ECM just died from age. @Mopar1973Man

In case you have not read it yet...........

[gipperkid]

@dave110 Yes. I have the ground mod and ac noise threads all saved in my favorites. Thank you though.

@Mopar1973Man @pepsi71ocean @IBMobile Just got an update from ACS. My ECM is done and on the way back, due to be delivered tomorrow.

 

Their findings report I am somewhat skeptical about seeing as how I drove my truck home on another ECM. Which I guess the "short" was actually the AC noise. Here is the email they sent:

"Great News!  Your unit has been completed.

Tracking number is- UPS 1ZR39F470354941703

Tech Notes: PLEASE READ BELOW ( there is a short in vehicle )

 
Our findings: You unit came in shorted out, your... unit arrived dead, APP pedal, lift pump circuit, CPU as well as your pins were reflowed. New flash chip as well as latest updates ( your engine wiring harness is in short!!!)

Prior to installing repaired unit: You must have repaired your short. Do protocol maintenance prior to installing the unit ' wiring , battery & terminals, alternator, sensors, etc... Please tend to all codes present, if there are ANY p0600 to p0609 codes please MUST replace batery & terminals prior to installing unit. All short in vehicle must be repaired. If there are any TSB (Technical Service Bulletin)  they must be tended to prior to installing unit. Make sure all parts replaced are OEM(Original equipment manufacturer) parts are a MUST! All Problem in vehicle must be tended to prior to installing unit ( failure to do so will result in damage to the unit and it will not be covered under warranty).

@Mopar1973Man @pepsi71ocean Received my ECM from ACS today. All looks good. I did get my original ECM back. Once the ground mod is done I'll get the repaired ECM installed and see what we have.

[gipperkid]

UPDATE!! Finished the ground mod last night and installed my repaired ECM from ACS. Truck started and runs fine, did not have time to check AC noise but will do so tonight. I did have a check engine light. With the key trick I got P0230, P0382, P0380, P0521, P0118, P0113, P0237. But dummy me didn't disconnect the batteries when I unplugged sensors and the alternator for the ground mod and I'm guessing using the wrong ECM threw some codes as well since one of the codes was for oil pressure. But on the second start the CEL was off. So far only have driven 30 miles and no issues. Thank you ACS!

@Mopar1973Man Just tested ac noise.

 

Passenger battery:

Max .010 at the terminals.

Max .016 at the alternator post.

13.92 volts at idle on hot engine

 

Driver battery:

Max .010 at the terminals

13.90 volts at idle

 

[Mopar1973Man]

Looks good. 

 

I guess you'll be considering sending the ECM to Auto Computer Specialist and have them fix that WTS light issues.

did you have a chance to check out the Reman Mintt ECM?

Apparently they dont have ECM's for ghe Cummins. At least I couldnit find one. Do you know if any one who has used them?
