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...

Fault Condition: Code SID 253 will set when there is an internal sum error within the Engine Management System (EMS) Module. If FMI 2 is displayed, the engine will not start and the EMS software must be replaced. If FMI 12 is displayed, the EMS Module may be reprogrammed or replaced. Contact Mack OneCall before reprogramming or replacing EMS Module.

Fault Condition: A mechanical failure will set FMI 7 or FMI 12 will set if there is a failed device within the VGT SRA. Possible repairs: 1) If code SID 27 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the VGT SRA connector for poor connections.2) A mechanical failure will set FMI 7 or FMI 12 will set if there is a failed device within the VGT SRA.
