– A sequential error or part sub-type. Leading zeros suggest a fixed-width indexing system —the fourth recorded issue in category 004 . The dash repeats the negative-deviation syntax.

A programmable logic controller (PLC) on a production line monitors voltage at test point 24. Expected: 24.0V ±0.5V. Sensor reads 23.76V – a -0.24V deviation, logged as -24 (scaled integer). The DDNG module—say, “Drive Diagnostics Next Generation”—flags an intermittent drop. -004 is the specific fault: “undervoltage at servo driver 4.” The final 4 means “log only; continue operation.” An engineer later investigates, finding a loose ground terminal. The code allowed triage without halting production.
