Diagnostic Codes Table    
Code and Description     Conditions which Generate this Code     System Response    
2417-5 Ether Injection Control Solenoid : Current Below Normal     The Electronic Control Module (ECM) detects low current in the circuit. The ECM can only detect this condition when the output driver is not activated.     The code is logged.
Ether injection is disabled.    
2417-6 Ether Injection Control Solenoid : Current Above Normal     The ECM detects excessive current flow in the circuit. The ECM can only detect this condition when the output driver is activated.    This starting aid output is used to connect to a relay and/or a solenoid in order to control a starting aid system. Typical starting aid systems will inject ether into the intake manifold in order to aid starting of the engine during cold-weather operation. The output is automatically controlled by the ECM.The lower value from the coolant temperature or intake manifold temperature sensor is used to determine if conditions require the use of the starting aid.If one of the temperature sensors has a circuit fault, the reading from the other sensor is used.The starting aid output is enabled for a maximum of 30 seconds while the engine is cranking and the temperature reading is below 0 °C (32 °F).The starting aid output is discontinued when the engine starts. The starting aid output is also disabled if a condition that prevents fuel injection occurs.An override parameter on Caterpillar Electronic Technician (ET) allows the technician to activate the ether system. The test is only functional when the engine speed is zero rpm. Access the test via the "Override Parameters" screen on Cat ET.

Breathing ether vapors or repeated contact of ether with skin can cause personal injury. Personal injury may occur from failure to adhere to the following procedures.Use ether only in well ventilated areas.Do not smoke while changing ether cylinders.Use ether with care to avoid fires.Do not store replacement ether cylinders in living areas or in the operator's compartment.Do
