JLG Scissor Lift 67 Fault Code: Error Hand Setp1
Also called Indicates OEM Accessory Problems - Accessory Fault
Error Hand Setp1 · ai-assisted, editor-reviewed · Last updated 2026-07-13
TL;DR
Code 67 (SPN 91 / FMI 11) on JLG scissor lifts flags an OEM accessory problem reported to the host control system, sometimes tied to no motion interlocks. It is a hardware inputs/outputs fault, and the fix depends on the specific accessory installed on the machine.
Medium severity. Code 67 does not by itself indicate a structural or hydraulic failure, but it can block machine motion through interlocks and may point to a wiring or module problem in an attached accessory system. Treat it as a stop-and-diagnose issue before continuing operation.
What does JLG Scissor Lift error code 67 mean?
Fault code 67 on JLG scissor lifts corresponds to SPN 91, FMI 11, and is described as 'Error Hand Setp1' or an OEM Accessory Fault. This means the machine's host control system received a fault report from an accessory module that is not part of JLG's core lift control, such as an OEM-installed add-on system.
The fault is filed under the hardware inputs/outputs group, meaning it relates to physical wiring, sensors, or discrete signal states rather than a software or communication timeout. One listed cause ties this code to 'no motion interlocks,' meaning the fault can be linked to the interlock system that normally prevents movement unless safety conditions are satisfied.
Because the accessory in question is OEM-specific and not a standard JLG component, the exact meaning and required fix vary by what accessory is mounted on the lift. JLG's own documentation points users back to the accessory manufacturer's paperwork rather than providing a universal repair step.
Common causes of 67
- The OEM accessory module has encountered a fault condition and reported it to the host control system.
- The accessory message flag ('control 1's request accessory fault') is set to yes; the code is retained or cleared depending on the current status of that flag.
- No motion interlocks are satisfied, which can trigger or relate to this fault being set.
How to troubleshoot JLG Scissor Lift 67: first checks
- Identify what OEM accessory is installed on the machine and pull its documentation, since JLG's own guidance directs users to the accessory manufacturer's literature to clear the difficulty.
- Check all wiring and connectors between the accessory module and the host control system for damage, corrosion, or loose pins, since this is filed as a hardware inputs/outputs fault.
- Verify whether any motion interlocks (platform gate, tilt sensor, or similar) are open or unsatisfied, since the fault is tied to a no-motion-interlock cause.
- Cycle the accessory fault flag by checking accessory status; if the request accessory fault flag clears, confirm whether the code clears with it.
- Inspect the accessory module itself for visible fault indicators or its own diagnostic codes, since the root problem originates in that module, not in JLG's core controller.
How the code clears
No dedicated reset procedure is listed for this code. JLG's documentation says to refer to the OEM accessory's own documentation to resolve the underlying fault. The code is described as retained or cleared based on the status of the accessory fault flag, so once the accessory module reports the fault condition as resolved, the code should clear on its own.
Frequently asked questions
What does JLG fault code 67 mean?
It means the machine's control system received a fault report from an OEM accessory module, or that a motion interlock condition tied to that accessory system is not satisfied. It is not a JLG-internal component fault.
Is fault code 67 the same as SPN 91 FMI 11?
Yes, JLG cross-references code 67 to SPN 91, FMI 11, which is the standardized diagnostic code used within the machine's control network.
Can I clear code 67 myself?
There is no separate reset procedure listed for this code. It is retained or cleared automatically based on the accessory fault flag status, so resolving the underlying accessory issue per that accessory's documentation should clear it.
Why does code 67 stop the lift from moving?
One listed cause is 'no motion interlocks,' meaning the fault can be connected to interlock conditions that block platform or drive motion until safety requirements are met.
What accessory is causing my code 67 fault?
JLG's documentation does not specify a particular accessory since this fault applies broadly to OEM add-on modules. You need to check what non-JLG accessory is installed on your specific machine and consult its manual.
Is code 67 a hardware or software fault?
It is filed under the hardware inputs/outputs fault group, meaning it relates to physical wiring, sensors, or discrete signals rather than a pure software communication error.
