FLEET MAINTENANCE
Transforming Equipment Support
Equipment uptime depends on fast, accurate troubleshooting and sometimes a phone call isn’ t enough
By Travis Myers
Recently, a technician working on a JLG 860SJ boom lift encountered a platform code 662 indicating lost communication to the platform controls. The issue initially appeared difficult to diagnose remotely because the machine would operate normally in ground mode, but the platform controls were not functioning, creating uncertainty about the root cause.
While situations such as this are common in field service, they often require several and often timeconsuming troubleshooting steps. Without direct visual access to the machine, technicians and support teams must rely on verbal descriptions, or written instructions sent via email or SMS message showing illustrations and possible locations of components
With the JLG Visual Remote Assistant, technical support experts can launch a live visual session with a technician using a smartphone or mobile device. After receiving a secure link via text or email, technicians simply tap to connect, without needing downloads or additional apps. Once connected, JLG support specialists can see exactly what the technician sees and guide troubleshooting in real time.
and connections, all of which can lead to delays.
In this case, the technician faced additional challenges, including difficulty identifying wiring harness connections and internal console components, a situation that can occur when equipment markings wear off over time or when machine configurations vary.
Through guided testing and inspection, however, a support specialist directed the technician to:
• Inspect platform module connections
• Verify voltage at specific pin locations
• Examine wiring connectors inside the console assembly
• Identify potential short circuits or loose wiring connections
