Clark OBD Codes

Working on a clark CMP25L
Was able to retreive the following OBD II code in the following order: 48, 54, & 12.
When you first start the truck it immediately throws a check engine light.
Does anyone have a list of these codes?

We are all set. The first two codes were just nuisance code. The truck sat for over a year without being started and the battery was stone dead. We charged the battery & cleared the codes. The truck seams to be running fine now....false alarm but thanks for the input!!!
