Technical Insight for Fleet Managers: JLG machinery utilizes complex load-sensing systems and electronic control modules (ECMs) that vary significantly by serial number. To prevent control system failures or safety risks, always verify your machine’s specific series (e.g., ES vs. RT) before beginning a service task. Using the correct factory-issued wiring diagrams is the only reliable way to diagnose sensor faults and interlock errors without risking damage to the main control board or violating ANSI/SAE safety standards.
