2nd Gen Non-Engine/Transmission Engine codes

[DEWright]

2002 3500, truck throwing two codes, p0500, and 00122. These seem to deal with the apps. has anyone seen these codes and what specifically did you do to correct the problem? Truck is showing no symptoms out of the ordinary. Have not tried resetting codes, but that is next on the agenda. Thanks.

You'ld probably have better luck in the 24v section...
