JLG error codes

JLG E3 series electric scissor lifts (older generation)

These machines do not give a fault number: the JLG analyser shows a text message, and the diagnostic light flashes out the group flash code (e.g. 2/2). In our database the message is also the code; we give the flash code with every message. Below are 26 messages with the original message from the manufacturer's manual and its description. They apply to these machines: JLG E3 series, manuals for the ranges 1532–2646 and 1532–2658. Source: JLG Service and Maintenance Manual E3 series (3120762, 3120878), help messages and flash codes tables.

The descriptions are quoted from the manufacturer's service documentation and are for guidance only. Clearing codes, calibrations and repairs are carried out by a qualified service technician according to the manual for the specific serial number. A machine with an active blocking code must not be used until the cause has been removed.
