ISP – WIRING
NOT MAPPED
PROPERLY 45102 The order of the ISP current
feedback wiring in the 12-pin
connector does not match
what the controller expects.
Y Verify that the proper signal wires are
connected in terminations 3-6 and the
proper current feedback wires are
connected in terminations 7-10 of the 12-
pin connector. Next, check the integrity of
the controller pins and the harness
terminations by removing each socket,
inspecting, and reinserting.
Verify that the proper controller is
installed. Disconnect the Lift, Tele, and
Fork Valve controllers and cycle power.
Under Diagnostics/Versions, verify that
only the UGM, Joystick and ISP are
reporting a software version (??? for the
other controllers).
