wire is installed, the "Clutch Switch" status will
always indicate "OFF". Engines that were built after
JULY 1999 use only one type of ECM that can be
configured for "Basic" or "Full Feature" operation.
A new parameter was added in order to provide
this flexibility. The "Truck Manufacturer" parameter
was added in order to allow the configuration of the
"GM Basic" operation or the "Other Full Feature"
operation. This parameter is programmed at
Caterpillar when the engine is built. The parameter
for "Transmission Style" is not available for engines
that have software that is dated prior to SEP00
and the parameter for "Truck Manufacturer" is
programmed to "GM". SEP00 and newer engines
that are programmed to "GM" use the "Transmission
Style" parameter. The factory default for the "GM"
setting is the "Universal" option. The "Universal"
option provides identical features as the "Basic"
system that is described above. If the "Transmission
Style" parameter is programmed to the "Universal"
option, a jumper wire must be installed between the
clutch switch input and the sensor common when an
automatic transmission is installed. Otherwise, the
"Transmission Style" parameter can be programmed
to match the specific arrangement of the vehicle.
If the problem is with undetermined
Cruise/Idle/PTO kickouts use the following
procedure:
Operate the vehicle in "Cruise/Idle/PTO" mode.
After the kickout, review the status parameter on ET.
The status parameter on ET indicates the cause.
This must be performed before the ignition key
switch is turned OFF. It is important to remember
that the parameter will only indicate the last kickout
since the ECM has been powered by the input for
the ignition key switch.
The following kickout status parameters are
available:
"Cruise Kickout"
"Idle Kickout"
"PTO Kickout"
"Fast Idle Kickout"
