Applicable truck models
This document applies to Caterpillar on-highway truck engines in the 3406E, C-10, and C-12 families. The specific configuration referenced is the C-12 Truck Engine 9NS00001-UP, though the bulletin also covers serial prefix groups 8YS, 5DS, and 1LW. The diagnostic code 0244-02 is triggered when the ECM personality module is changed, a new ECM is installed, or the unswitched battery connection is disconnected from the ECM. A large number of logged codes may indicate the unswitched +Battery line is connected to a switched battery or that a battery disconnect switch is installed in the circuit.
