I am having issues getting my adapter to connect on my truck. Do I need to use a different adapter? I have the ignition key turned on.

Adapter: OHP FORScan OBD2 ELMconfig Adapter

 

Did you first set up the adapter in Forscan?

 

...also flip the switch the other direction and try again.

 

Sometimes you have to hook up a battery charger. The BMS will cut off aux power to several things at the most inopportune times. I found out the hard way, right in the middle of trying to enable the Bambi mod.

And, depending on the adapter, you may have to download drivers for it to work. I did.

 

Is the fuse good?
