Introduction
Understanding the Electronic Controls
This booklet is to aid you in choosing appropriate
programmable values. Some features fall into a
“non-programmable” or “programmable only by your
authorized Cat dealer” category. While you may not
need to be concerned about programming these
parameters, we have included them in this booklet so
you can have a greater understanding of the Caterpillar
electronic system.
Cat electronic truck engines offer a wide range of
features, these include but are not limited to:
✔ Maximum Vehicle Speed Limiting
✔ Progressive Shift
✔ Engine Idle-Shutdown Timer
✔ Wide variety of Cruise Control features
✔ Engine Brake Control
✔ Dedicated PTO control features
✔ Engine Monitoring System
✔ Engine Diagnostics w/ fault logging including
“snapshot” recording
✔ Numerous Trip Recording options
✔ J1939 Data Link
✔ ATA (J1587) Data Link
✔ Cooling fan control including A/C high pressure
Not all of these features fall into the “customer
programmable” category. Some features, like the
ATA Data Link, have to do with the way the engine
electronics are integrated into the truck and drive
train electronics. Another example is the setting for
tachometer calibration, which comes preset from the
truck factory and should not be changed. (In fact, most
features come with a preset value from the factory.)
Other features, like password protection, can only be set
by a customer.
