Fault Memory And Retrieval; Hydraulic Solenoid Valve Functions - Toro Reelmaster 6700-D Operator's Manual

If the output LEDs are on as specified, but the machine
does not function properly, this indicates a non-electrical
problem. Repair as necessary.
Note: Due to electrical system constraints, the output
LED's for "START", "PREHEAT" and "ETR/ALT" may
not blink even though an electrical problem may exist for
those functions. If the machine problem appears to be with
one of these functions, be certain to check the electrical
circuit with a volt/ohm meter to verify that no electrical
problem exists to these functions.
If each input switch is in the correct position and
functioning correctly, but the output LEDs are not correctly
illuminated, this indicates an ECU problem. If this occurs,
contact your Toro Distributor for assistance.

Fault Memory and Retrieval

If the Controller senses a fault on one of the output
solenoids, it will flash the machines diagnostic Lamp (Reel
Diagnostic lamp on console or green Diagnostic lamp
under console) and store the fault into the Controllers
(ECU) memory. The fault can then be retrieved and viewed
with the Diagnostic ACE hand held tool or a lap top/PC at
anytime. The Controller will store one (1) fault at a time
and will not store another different fault until the first fault
is cleared.
Retrieving Fault Information
Retrieving Stored Faults (Do not sit in seat)
1. Rotate ignition key to Off position.
2. Connect the Hand held Diagnostic Tool to the desired
Controller Loopback Connector (use the proper
overlay).
3. Move the Joystick to the Raise position and hold.
4. Rotate ignition key to On position, and continue to hold
the Joystick in Raise position until the top left
Diagnostic Tool light comes on (approx. 2 seconds).
5. Release the Joystick to the center position.
6. Hand held Tool will now playback the fault retained in
the Controller memory.
Important
The display will show eight (8) individual
records with the fault displayed on the 8th record. Each
record will be displayed for 10 seconds. Be sure to have
the Diagnostic Tool display on Outputs to see fault. The
Problem circuit will be flashing. Records will repeat until
key is turned off. Unit will not start in this mode.
Clearing the Fault Memory (Diagnostic Tool not
required)
1. Rotate ignition key to Off position.
2. Turn Backlap Switch to the Front or Rear Backlap
position.
3. Turn the Reel Control Switch to Enable position.
4. Move the Joystick to the Raise position and hold.
5. Turn the ignition key to On, and continue to hold the
Joystick in the Raise position until the Reel Control
Lamp starts to flash (approx. 2 seconds).
6. Release the Joystick and turn the Key Off. Memory is
now cleared.
7. Turn the Backlap Switch to Off and Enable Switch to
Disable position.
Important The Diagnostic ACE display must not be
left connected to the machine. It is not designed to
withstand the environment of the machine's every day use.
When done using Diagnostic ACE, disconnect it from the
machine and reconnect loopback connector to harness
connector. Machine will not operate without loopback
connector installed on harness. Store Diagnostic ACE in
dry, secure location in shop, not on machine.
