(code descriptions may vary)    Comments    
2417-5     626-5     Ether Injection Control Solenoid : Current Below Normal     The code is latched. The code is logged.
Ether injection is disabled.    
2417-6     626-6     Ether Injection Control Solenoid : Current Above Normal     The code is latched. The code is logged.
Ether injection is disabled.    The ether injection system will improve cold weather starting of the engine. The engine Electronic Control Module (ECM) controls the ether injection system. The ether injection system is disabled if there is an active engine shutdown.Activation of the ether starting aid is based from a map using the coolant temperature, intake manifold temperature, and atmospheric pressure. Refer to Illustration 1.

The following conditions must be met for the ether injection system to be enabled:
Ether injection is set to enabled in Cat ET
Engine coolant temperature is less than the "Start Aid Selection Temperature - Coolant". Refer to Illustration 1.
Intake manifold temperature is less than the "Start Aid Selection Temperature - IMAT."
Coolant temperature and intake manifold air temperature are within 11° C of each other.Industrial Application Schematic
