Ecu Programming - Cannondale 5002401 Service Manual

ECU PROGRAMMING

The ECU is "programmed" with three types of infor-
mation. the operating code (also known as the "hex"
file, the engine calibration file (also known as the
"map"), and the vehicle variables or "calibrations."
Calibrations are stored in the map file but are specific
to the throttle body and injectors installed on the
vehicle.
Any programmed information can be changed.
using the Cannondale Diagnostic and Maintenance
Tool. Refer to "Cannondale Diagnostic and Mainte-
nance Tool Version 2.0" starting on page 21.
ECU diagnostic connectors
ATVs and motorcycles have a diagnostic con-
nector to connect the software tool PC to the vehicle.
• On 2001 and 2002 Motorcycles, the diagnostic
connector is located near the ignition coil on the
top of the cylinder head.
• On 2003 motorcycles, the diagnostic connector
is located near the main fuse under the seat.
• On 2001 - 2003 ATV the diagnostic connector is
located near the radiator shroud on the left side
of the ATV.
The tool is a combination of a specially developed
Windows- based software program and a data cable
used to connect your PC or pocket PC computer to
your vehicle. With the tool, you can read fault codes,
install engine calibration files, set vehicle rpm, and
monitor engine operating parameters.

Reporting system faults
The ECU is capable of reporting system hardware
malfunctions during operation. It reports current
problems and does not store problem "faults" in
memory.
System faults are read from the ECU using the
Cannondale Diagnostic and Maintenance Tool, a
Windows-based PC program enabling communi-
cation between a PC and the vehicle ECU. The ECU
does not store intermittent faults; the faults reported
are occurring at the moment when the ECU Fault
Report window is selected in the software tool. A
special communication cable is needed to connect
the vehicle to a PC. Refer to "Cannondale Diag-
nostic and Maintenance Tool Version 2.0" starting on
page 21.
This manual provides step-by-step fault diagnostic
testing based on the actual fault reported by the
software tool. Refer to "Fault Troubleshooting"
starting on page 42.
