Hi Guys, if been searching to forums for similar issues I am having but I can't seem to find a solution.
2005 Dodge Ram 1500 4.7L Auto, NGC3
Running most current software 3.6
Tried older version from USB drive that came with MPVI
THE PROBLEM:
I am getting an error controller unlocker: Timed out when ever I turn the key on right away.
Steps by step
Unplugged all external devices
Plug MPVI into OBDII port
Plug MPVI into laptop
Start program VCM Editor from the source and select run as administrator
Select flash tab and read vehicle
Select Read Entire
Select Read tab
It asks me to cycle the key switch off wait 3 second turn back on
Ignition off reader goes in to waiting mode
Wait 3-15 seconds and turn ignition back on
VCM says requesting access for a split second then immediately goes to failed
Error: Controller Unlocked: Timed out.....
I believe the problem here is the tool is requesting access too quickly once the ignition is turned back on and causing it to fail I could be wrong but I have checked my complete electrical system body grounds, unhooking powered devices usbs, radio, and sub amp made sure battery has good charge, hard reset the ecm by umhooking for multiple hours etc... iv sent a request in to tech support but no word back yet I'm and just waiting to play with this thing but I can't even read and save my stock tune.
I did try clicking read and when it shows the turn ignition off I turn it off but before turning back on I unplugged the USB cable. Turn the key on and wait 3-15 seconds and plug usb back in but then it just times out I wonder if unhooking at the OBDII port would work cause I wouldn't be looking the connection to the computer between the MPVI and laptop just the MPVI to OBDII port.
VCM scanner works I can data log the PIDs and watch what the truck is doing. But I can't mess with the tire size or gearing or adjust my speedo when I click the green power looking button I get a blank white screen pop up but nothing in the box I'm guessing this is an unrelated issue for now but I do need to correct my speedo for some reason it is off by 5-10 MPH depending on speed the faster I go the more off it is 30=35, 40=48, 60=70 etc...
Anyways any advice things to try?
