Description
This output is to be used for control of “keyswitch” input of an ECU. If the particular ECU does not have
keyswitch or a similar input, it can be used for control of DC power for the ECU.
The output closes together with PRESTART (PAGE 341) and remains closed for the entire duration that the
engine is running. It is opened at the moment that the engine comes to a stop (i.e. together with the FUEL
SOLENOID (PAGE 326)).

IMPORTANT: This LBO also affects evaluation of Sd ECU Communication Fail (page 374) or
Wrn ECU Communication Fail (page 360) alarms. With configured LBO ECU Power Relay,
these alarms are evaluated only when this LBO is active. Without configured LBO ECU
Power Relay, these alarm are evaluated all the time.

Description
This output is active when the ECU sends an active “red lamp” flag, i.e. it has detected a critical malfunction
and the engine should not be operated until a service check is performed. This flag is taken from the DM1
frame on standard J1939 ECUs. Some ECUs provide this flag in their own proprietary frames and some do
not provide the flag at all.
