Diablosport Forums

I recently bought the Diablo Sport Sprint S1000 for my 2011 Tahoe 5.3
I notice that it has 3 leds on the device, however they do not light up when plugged in. I am curious to know if they are supposed to or not? No other real way to know if it's working or not. Thanks.

check your cig lighter and/or aux power fuses to make sure your OBD port is actually getting power.. lights should be on...sounds like a blown fuse, no power at your OBD port.

Thanks. Was blown fuse. Go figure it was the obvious thong haha.
