After the kickout, review the "ET Status" parameter.

The "ET Kickout Status" parameter indicates

the cause. This must be performed before the

ignition key switch is turned OFF. It is important to

"AT/MT/HT Option 2"

remember that the parameter will only indicate the

last kickout since the ECM has been powered by

"AT/MT/HT Option 3"

the ignition key switch.

"AT/MT/HT Option 4"

The following Kickout Status parameters are

available:

A Service Brake Pedal Position (Switch 1) is required

"Cruise Kickout"

for all configurations. The Service Brake Pedal

Position (Switch 1) connects to the ECM through

"Idle Kickout"

connector P1 terminal 45. The Service Brake Pedal

Position (Switch 2) connects to the ECM through

"PTO Kickout"

connector P1 terminal 64. The Clutch Pedal Position

Switch connects to the ECM through connector P1

"Fast Idle Kickout"

terminal 22. The neutral switch connects to the ECM

through connector P1 terminal 62.

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.
