what do these codes mean?
 

i just ran a code check on the black beast and got the following codes-1388, 1693, 0230. i would like to know what each of these are for, what they mean, and how do you fix them?? thank you in advance.

Codes can be found in our Tech Facts section.

I also like this place to fill in the gaps.

1388 is Auto Shutdown Relay circuit
0230 is Transfer pump circuit out of range.

Not sure what they mean or how to fix them though.

1693 is the ever popular "Companion Code" meaning there is a code in the ECM that the PCM can't see.

How to fix them will depend heavily on what year your truck is, it would help to fill out your signature
(User CP, then "Edit Profile" then fill in the signature box with year, make, model, mods, etc)

Phox, do you know what causes them or does anyone know? i have had a little trouble with the black beast lately and hope to get it worked out soon. thanks for the help!

I would check the easy stuff first...

Check you relays under the hood... You might have a bad ASD relay... I think it also powers the LP pump...

Try trading the ASD relay with something else...
