ive had my sct for 3 years now, i use it now and again too swap the octain power. i went to plug it in and has no power . i checked all my fuses even cig fuses . anyone else have this problem ? i wanna switch it back to 87 and get it off the 93 tune .

 

You should send hemifever an email, if you haven't already.

 

+1 Yeah I would just shoot Sean an email about it. I am sure he can help.

 

Make sure that the SCT OBDII connector is plugged tightly into the truck's OBDII port and check to ensure that all of your pins in the SCT connector are straight and not bent. If all that checks out and no blown fuse issues are found, contacting HemiFever is definitely the next step..

 

Should have 12 volts on pin 16 of the data link connector. (pink wire) Gets power from fuse 12 in the box on the side of the dash. Goes thru a connector before getting to the OBD port.... Bunch of other stuff on that circuit though, power mirrors, radio, glove box light, dome lights, etc.

 

thanks heyyou ! you always a big help on this forum ! ill get back when i find out ! !

 

Will a generec OBDII reader work if you plug it in? If so, then it may be your SCT unit. If not, I suspect the circuit that HeyYou referenced.

 

my sct i bumped the plug on it and it only works when i wiggle it and hold in to the side a little. try messing with it like that, most likely the pins arn't contacting the female side of the port

 

I went to advance auto parts and there scanner didn't work either , all fuses are good all lights work on dash . Now I'm outta luck . There could be a loose wire anywhere fml .
