JLG 3246ES: Platform will not raise or lower

Likely cause: Discharged battery, an active fault code blocking the function, platform overload or a faulty valve or solenoid valve of the pump. Diagnosis: Check the battery voltage, read the fault code and remove any excess load from the platform.

JLG 3246ES: Machine will not drive

Likely cause: Joystick not in neutral at start-up, an active tilt sensor blocking driving at height, or a controller communication error. Diagnosis: Set the joystick to neutral, lower the platform, level the machine and read the fault code.

JLG 3246ES: Tilt alarm

Likely cause: Working on uneven ground, or a mis-adjusted or damaged tilt sensor. Diagnosis: Place the machine on level ground; if the alarm does not clear, a service technician calibrates or replaces the sensor.

JLG 3246ES: Platform overload

Likely cause: Capacity exceeded or a load sensor out of calibration. Diagnosis: Remove the excess load; if the error remains, the load cell must be calibrated at a service centre.

JLG 3246ES: Weak or short run time on the battery

Likely cause: Sulphated or worn cells, a faulty charger, corroded or loose terminals. Diagnosis: Measure the cell voltages, check the charger and terminals and replace the batteries if necessary.

JLG 3246ES: Will not extend to full height (pothole protection)

Likely cause: The pothole protection bars have not deployed, or the deployment sensor is damaged. Diagnosis: Inspect the pothole protection mechanism and its sensors.

JLG 3246ES: No control from the upper control box

Likely cause: Loss of communication between the platform and the chassis: a chafed cable, corroded connectors or a faulty controller. Diagnosis: Test from the lower control box and check the coiled cable and the connectors.

JLG 3246ES: Soft hydraulics, or the platform slowly descends

Likely cause: Worn cylinder seals, air in the system, contaminated oil or a leaking holding valve. Diagnosis: Check the oil level and condition and the tightness of the system; repair at a service centre.

JLG 3246ES error codes: 206 codes explained

JLG uses the JLG Control System. The flash code has the format group/subgroup (e.g. 2/1), and the full DTC is 3 to 5 digits (e.g. 255, 437, 662), read with a JLG analyser. The first digit indicates the system the fault relates to.

Below you see the code and the original manufacturer's message. Open a code for the likely cause, what you can check yourself and when to call service.
