Proceed to Test Step 3.
Result: The affected CEM is not a certified match for the engine.
Repair: Remove the affected CEM and replace the affected CEM with a certified match for the engine. Refer to Disassembly and Assembly for removal and installation procedures. When the new CEM is installed, the"Aftertreatment Identification Number Module" will begin communicating with the ECM and the diagnostic code will be cleared.
When determining if a CEM is a certified match:
The engine ECM will only communicate with the CEM if the total lifetime hours of the engine are less than 100. If the hours are greater than 100, the information from the CEM identification plate must be programmed into the ECM by using Cat ET.
