This diagnostic trouble code is generated if one of the following conditions occurs: The key is held in the ELX position for more than 2 seconds with the engine running. The voltage supply (ELX) is not present at the engine control unit, cab control unit, or immobilizer control unit with the engine running. The engine…

This diagnostic trouble code indicates a data transfer problem between the Engine Control Unit (ECU) and the Selective Catalytic Reduction (SCR) temperature module. The ECU is unable to receive data from the SCR temperature module, which can impact the accurate monitoring and control of the SCR system.
