Cummins fault code 111 indicates an internal hardware failure within the Electronic Control Module (ECM). This is a critical fault that requires immediate attention as it can affect engine performance, fuel injection, and sensor readings.
It is not recommended to continue operating the generator with an active SPN-111 fault code. The ECM failure may cause erratic engine behavior, incorrect fuel injection, or sudden shutdown. Have the unit diagnosed by a qualified technician immediately.
