Checking OUTPUTS
1. After installing Diagnostic ACE, turn ignition key switch ON, but DO NOT start the
engine.
NOTE: After installing Diagnostic ACE and turning ignition key switch ON, the
“
INPUTS DISPLAYED
” LED will be on. This indicates that the ECU and Diagnostic ACE
are operating properly. If the green controller diagnostic lamp on the machine comes
on, but the “
INPUTS DISPLAYED
” LED does not come on, there is a problem with the
Diagnostic ACE.
2. Push input-output toggle button so “
OUTPUTS DISPLAYED
” LED is on.
NOTE: It may be necessary to toggle between “
INPUTS DISPLAYED
” and “
OUTPUTS
DISPLAYED
” several times to do this procedure. To toggle back and forth, press toggle
button once. This may be done as often as necessary. DO NOT hold button.
NOTE: Red text on overlay decal refers to input switches and green text to outputs.
3. Sit on the seat and attempt to operate desired function of machine – DO NOT start
the engine. The appropriate output LED’s should illuminate to indicate that the ECU
is turning on that function.
If any output LED is
FLASHING ON
and
OFF
, this indicates an electrical problem
with that OUTPUT. To reset a flashing LED, turn the key switch OFF, then back ON.
If no output LED’s are flashing on and off, but the correct output LED’s do not
illuminate, verify that the required input switches are in the necessary positions to
allow that function to occur.
If input switches are correct, but output LED’s are not correct, this indicates a
controller malfunction.
If output LED’s are correct, but machine does not function properly, this indicates a
hydraulic problem.
NOTE: Due to electrical system constraints, the output LED’s for “
START
”, “
PREHEAT
”
and “
ETR/ALT
” may not flash on and off, even though an electrical problem may exist
for one of those functions. If the machine problem appears to be with one of these
functions, see the troubleshooting charts in the Reelmaster 5100-D Service Manual.
Push INPUT-OUTPUT TOGGLE
so OUTPUTS DISPLAYED light is ON.
