Intermittent or Erratic Gauge Readings: Fuel level, temperature, or pressure gauges behaving strangely.
Unexpected Warning Lights / Codes: Diagnostic trouble codes (DTCs) that appear and disappear, especially codes related to sensor signal or power supply.
Component Failure: A component (like a solenoid) not working, even after replacement, often points to a wiring issue (power, ground, or signal).
Machine Will Not Start: Problems with power from the batteries to the ECM or starter circuit.
Engine Derating or Shutdown: Loss of signal from a critical sensor (e.g., coolant temp) can cause the ECM to derate the engine or shut it down to prevent damage.
