Fault Condition: A fault of FMI 3 will be logged if the IVS voltage is greater than 8.5 volts and the pedal position less than 1%. If the voltage is approximately 0 volts and the pedal position is greater than 50%, an FMI 5 will set. Possible repairs: Turn the ignition key OFF first. 1) If code SID 230 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the VECU connectors and wires for poor connections.2) Disconnect connector B from the Engine Management System (EMS) Module. Disconnect connector B from the Vehicle Electronic...

Fault Condition: Code SID 231 will set when the Vehicle Electronic Control Unit (VECU) is unable to send and/or receive information across the J1939 data line. If either the Vehicle Electronic Control Unit (VECU) or the EngineManagement System (EMS) Module loses communication on the J1939 data line, code SID 231 will set and the Electronic Malfunction Lamp (EML) will turn on. The fault will become inactive if communication resumes. If communication is lost on both the J1587 and J1939 data lines the engine will NOT run. Possible repairs: Turn the ignition key OFF first. 1) Disconnect the Vehicle Electronic Control...

Fault Condition: The Electronic Malfunction Lamp (EML) will turn on and code SID 232 will set when the reference voltage to the Electronic Fan Controller, Boost Pressure Sensor and Intake Air Temperature and Humidity Sensor is less than 4.5 volts or greater than 5.5 volts. If the voltage returns to 4.5 volts to 5.5 volts, the fault will become inactive. Possible repairs: Turn the ignition key OFF first. 1) If code SID 232 is NOT set, wiggle the harness and connectors to try to set the code. Visually inspect the EMS Module connectors for frayed wires and loose or corroded...
