Common Cummins CM2350 ECM Failure Symptoms

Due to managing complex variable geometry turbochargers (VGT), high-pressure common-rail fuel injection, and advanced aftertreatment emissions systems, a failing 4384700 controller often displays these common signs:

• Complete no-start condition or intermittent engine stalling while operating

• Total loss of communication with diagnostic tools, telematics, or J1939 data links

• Unexplained engine derate, sudden limp mode, or severe loss of power

• Multiple simultaneous sensor "voltage high/low" fault codes (internal 5V reference circuit failures)

• Erratic throttle response, engine misfires, or unstable idle speed

• Persistent Check Engine Light (CEL) or un-clearable active fault codes
