    How to kill VATS dead

    Finally got our PCMs to work and figured I would share it with anyone else that might run across this issue. Car won't start/crank, or the car starts and then dies.

    Setting the VATS to PWM rather than Serial will get the car to run. Turning off Codes 1626-1631 will let it stay running.

    So far so good with this setup.

    neat. the 93-95 60V6 SFI code actually works really similarly.
    1995 Monte Carlo LS 3100, 4T60E...for now, future plans include driving it until the wheels fall off!

      Ben did you search for this on HPTuners? I found a thread from 07 talking about it... It doesn't have the same codes listed as you do, but similar procedure.

      Disabling VATS on non-Alloytec V6 car PCMs
      http://www.hptuners.com/forum/showthread.php?12399-Disabling-VATS-on-non-Alloytec-V6-car-PCMs&highlight=pwm
      To disable VATS you must do the following: 1. Set the VATS value to "PWM" 2. Set DTC P1626 to "3 - No Error Reported" 3. Set DTC P1629 to "3 - No Error Reported" Additionally you might need to set 4. Set DTC P1630 to "3 - No Error Reported" 5. Set DTC P1631 to "3 - No Error Reported"


      I've also done this on my moms old 2000 Grand AM when it continued to screw up on her, except the procedure was slightly different in DHP. And I think that was passkey, but I'm not sure. Similar, you set the system to "disabled" then have to shut off codes otherwise it will only let the car run for a second, or just crank.

          What PCMs? There are literally dozens of different PCMs used by people on this board.

              Yeah....

              A little more specific would be nice...

              Service number...?

              BCC...?

              (Known) Applications...?

                  there are different service numbers, but the functionality and programming is pretty much the same between them from what I've seen.

                    If you have a DHP PowrTuner, you would do the following to disable VATS:

                    1. Under The Security Tab - Vehicle Theft Deterrent: Select "VTD_Present_On_Car and set to "False"
                    2. Under Diagnostics - Fault Reporting - DTC Fault Type: Set Codes 1626-1631 to "No Reporting"

                      when you set to disable, do you input a "1" or a "0" in the VTD present on vehicle box? I'm assuming a "0", but I want to make sure....

                        via boolean logic, a 0 for "VTD present" would mean it's not present.

                          that's what I thought, thanks.
