Verify Diagnostic Display Output Functions
B. If the output LED’s are on as specified, but the
machine does not function properly, suspect a non-
electrical problem (e.g. hydraulic component prob-
lem). Repair as necessary.
The Diagnostic Display also has the ability to detect
which output solenoids or relays are turned on by the
ECM. This is a quick way to determine if a machine mal-
function is electrical or hydraulic.
C. If each input switch is in the correct position and
functioning correctly, but the output LED’s are not
correctlyilluminated,thisindicatesanECMproblem.
If this occurs, contact your Toro Distributor for assis-
tance.
NOTE: Anopenoutput(e.g.anunpluggedconnectoror
a broken wire) cannot be detected with the Diagnostic
Display.

should illuminate on the Diagnostic Display to indicate

ETR and Diag. Lamp outputs can be checked with the
ignition switch in the RUN position and the engine not
running. For testing of the solenoid outputs (MSV1,
SV1, SV3, SVRV, SV2 and MSV2), the engine must be
running.
NOTE: If the “diag. lamp” output LED is blinking, this in-
dicates an ECM fault has occurred. Refer to Diagnostic
Light in this section for information on retrieval and
clearing of ECM faults.
