Section 4 – Troubleshooting Information
19. Flash Code F20: Height<>0% -
This message occurs if the platform height is not 0% after the
platform has been fully lowered during either STATIC lift
The platform must return to the same height each time it
is fully lowered.
Check DIAGNOSTICS / SYSTEM to check the height.
20. Flash Code F21:Height<>0% -
This message occurs if the platform height is not 0% before
the platform is raised during either STATIC lift.
The platform must be at 0% height when it is fully
lowered.
Check DIAGNOSTICS / SYSTEM to check the height.
21. Flash Code F22:Height<>100% -
This message occurs if the platform height is not 100% after
the platform has been fully raised during either STATIC lift.
The platform must return to the same height each time it
is fully raised.
Check DIAGNOSTICS / SYSTEM to check the height.
22. Flash Code F23:Height<>100% -
This message occurs if the platform height is not 100%
before the platform is lowered during either STATIC lift.
The platform must be at 100% height when it is fully
raised.
Check DIAGNOSTICS / SYSTEM to check the height.
23. Flash Code F24:Too Many -
This message occurs if too many static measurements are
taken during either STATIC lift or lower.
It is likely that there is a problem with the lift cylinder
pressure; the GP102 should only need about 10
measurements for most vehicles.
The SETUPS / HEIGHT SETUPS / MIN LIFT time could
be increased to force a longer time between static
measurements, but this should not be necessary.
24. Flash Code F25:Check Elev -
This message indicates a problem with the elevation switch
P2-10 during the STATIC phases.
The switch is either staying closed to a higher height, or
staying open to a lower height, than that recorded during
the DYNAMIC phase.
25. Flash Code F26:Check Elev -
This message indicates a problem with the elevation switch
P2-10 during the STATIC phases.
The switch is opening or closing at a different height than
that recorded during the DYNAMIC phase.
26. Flash Code F27:Bad Height -
This message indicates a problem with the height sensor
output P4-3 during the STATIC phases.
The height sensor output must be between 1.0V and 4.0V
at all times.
Check DIAGNOSTICS / SENSORS to see the output.
A reading of 0 V or 5 V is probably due to a wiring
problem.
27. Flash Code F30:Bad Heights -
This message indicates that the recorded heights are not
increasing during either STATIC lift, or are not decreasing
during either STATIC lower.
It may be possible to cause this problem by repeatedly
opening and closing the UP or DOWN switch during the
STATIC phases.
28. Flash Code F31:Reject Curve -
The DYNAMIC pressure curve is unacceptable.
An initial pressure peak when the platform lifted cannot
be found between 0% and 15% height.
Check the pressure sensor and lift cylinder hydraulics.
