CONDITION :This service bulletin addresses two conditions identified individually below. Both conditions concern the
engine management system of affected vehicles.
(1) Field reports of intermittent engine sta lling hav e been att ri but ed to ea rly re lea se s of the MC1000 E CU
operating code. The operating code is something like the operating system in an ordinary personal
computer or PC (example: Windows 95). The operating code should not be confused with the calibration
file; that file contains mapping and vehicle specific calibrations.
.
(2) Field reports indicate hard starting and/or difficult cold starting experiences. These experiences have
been attributed to the cold starting “strategies” programmed in early releases of the calibration files on
affected units. A calibration file is something like the software running on a particular operating system
(example: MS Excel or Word).
SOLUTION :(1) For condit ion 1 above, a revised ver sion of the MC1000 operating code has been developed and must
be installed on all affected models. A special MS-DOS program has been developed to install the revised
code file to the vehicle ECU.
(2) A new calibration file has been developed and should be installed into the vehicle ECU after the revised
operating code (Condition (1) above) has been installed.
This service bulletin includes step-by-step instructions to correct both conditions in the same “work procedure.”
PARTS :The kit (P/N 912-5001986) including PC software programs, a data cable, and user manuals is necessary
to perform the instructions of this service bulletin. The kit has been shipped to dealerships. The software
installation is a prerequisi te to per fo rm in g any wo rk. Consult t he kit documentation for more details.

NOTE :
Before starting this procedure, we strongly
recommend that you read the Cannondale
Diagnostic Tool Manual (P/N 912-5001985) included
with kit (P/N 912-5001986). The manual contains
impor tant background information and explanations
that will be helpful to know before you attempt this
simple, but very technical procedure. We also
recommend that the service technician performing
the work have moderate PC skills.
1.From the Windows START menu select
DealerCal.exe from the Cannondale
Diagnostic and Ma intenance program group.
The Cannondale Diagnostic Tool main menu
will open. See example below.

4.Press the vehicle engine start button briefly.
This will activate the engine management
circuits. The green LED on the data cable
block should be lit. Look at the block to
confirm that it is on. If you read the
Cannondale Diagnostic Tool Manual, you
would have learned that this LED stays on
while the ECU is active and that the ECU
remains active for only 2 minutes if
communications are not occurring- then it
shuts down automatically. If the light goes out
anytime during this pr ocedure, just press th e
engine start button again to turn it on.
2.Connect the data cable to the vehicle and PC.
See the Cannondale Diagnostic Tool Manual
for details.
3.Disconnect the vehicle starter solenoid
harness lead. The solenoid is mounted on the
inner side of the left engine r ail just below the
fuel filter mount. In the illus tration below, the
radiator is shown removed for clarity; the
5.Click the OPEN Calibration file (saved)
button in the Cannondale Diagnostic Tool
main menu.
Then, select the file name d 00202 located in

the transfer of data occurs qu ickl y.
6.Make sure “00202” is displayed at Numeric
Cal ID. If it is not, repeat the previous step.
7.Make sure the green LED on the data cable
block is still lit. If its not press the engine start
button to turn it on.
Now, click the RECIEVE Calibration file(from ECU) button.
When the Choose Receive Option window
opens select “Selec t to Receive only Throttle
and Injector Calibr ations” and click OK. This
option reads only the TPS sensor closed
(volts), TPS open (volts), Throttle Body
Leakage, Injector flow rate, and Injector offset
variables from the current calibration file in
the ECU and does not read the calibration
file. These will be needed for the new
calibration file installation later because the
operating code installation wipes them from
the ECU memory. Because the program is
reading this relatively small set of vehicle
8.The vehicle’s variables have now been
merged with the new calibration file (00202)
that you opened in the program in the first few
steps. Write down the val ues d isplay ed in the
main menu (see arrows below). When you
write them down you are creating a kind of
backup just in case you have computer
difficulties (accidentally closing the
Cannondale Diagnostic Tool). If you don’t
have a problem, the next few steps will
transfer this information to the ECU following
the operation code transfer. But if you do
encounter a problem, the Cannondale
Diagnostic Tool enables you to input th em to
the ECU. See Updating Calibrations and
Setting the Throttle Body in the tool manual.
9.Press the engine stop button.

will be installed into the ECU.
When the send complete window displays,
