I have a 99 Camaro with an LS6 and supercharged. I removed the abs and traction control. I added the line lock and proportioning valve.
Now, I am getting DTC codes U1000 and U1040, yes I would have expected the u1040 but using EFi it is set to No Mil in engine DTC MIL enablers and X- not reported in Engine DTC Processing enablers. This sets the "Service Vehicle" light, along with the Brake and ABS/INOP Lights.

Some direction as to how to turn off the service engine and brake lights would be appreciated. My under standing for the ABS/INOP the only to turn that off was either you cut one leg of the lLED or put black tape over it.

Thank you
