Basics

WHAT IS THE CANNONDALE DIAGNOSTIC TOOL?

The Cannondale Diagnostic Tool is a Windows-based software program and special data cable that enables you to connect and communicate with vehicles using the MC1000 Engine Management System. The software is installed on a PC or Pocket PC, then the PC (or Pocket PC) is connected to the vehicle wiring harness via the special data cable. Once the software is installed in the PC and communication with the vehicle ECU is established, here’s what the tool can do:

• Send a calibration file from the PC t o the vehicle ECU.

• Receive a calibration file from the vehicle ECU to the PC.

• Set the vehicle throttle body and injector variables

• Monitor the (vehicle) ECU operating parameters

• Read system faults

INSTALLING THE SOFTWARE

To install the Cannondale Diagnostic Tool in your PC, insert the installation CD in your computer CDROM drive. Use the Windows explorer and open the program Setup.exe on the software CD. Follow the step-by-step instructions. When the installation is complete, go to the security set-up. See next heading.

SECURITY SET_UP

After the software has been installed on your PC, click on the Windows START button in the lower left corner of your desktop go to Cannondale DIagnostic and Maintenance Program group and open SecurityCode.exe. Follow the instructions that are displayed in program window. When the security code is entered (after you call Optimum Power to get it), you can begin using the software.

ALWAYS MAKE SURE THE VEHICLE BATTERY IS FULLY CHARGED

Before performing any diagnostic work on the vehicle make sure the battery is at full charge. If the battery voltage is low the ECU power relay may drop out and shut off the ECU. If the battery is not fully charged the ECU power relay can drop out while the engine is cranking over. Why? During crank over the battery voltage could drop below the needed latch voltage of 10 volts.

ALWAYS MAKE SURE THE ECU IS POWERED-UP

The vehicle’s ECU operates on a relay controlled power source which is separate from any lighting or starting electrical systems. The relay “latches-in” the ECU when the crankshaft sensor detects flywheel movement. If the ECU senses inactivity (no engine start or communications between the PC and ECU) for two minutes, it powers down. If you try to communicate with the ECU when it is powered-down or off, the “Failed to Unlock System 125” message will display.

POWERING-UP MOTO ECU’S

On motorcycles, power-up is relatively simple. Press the green start button and release it without starting the engine. When the system is powered-up the green LED on the data cable “block” will light.

P/N 912-5001985 Printed : 11/8/01

POWERING-UP AT V ECU’S

To power-up the ECU on ATVs you have to switch the ignition switch to the “ON” position, then switch the engine switch to the RUN position. Then, press the green start button and release it without starting the engine. When the system is powered-up the green LED on the data cable “block” will light.

After 2 minutes of inactivity, the ECU will power-down automatically except with the ATV the data cable block green LED will not go out. It will remain lit as long as the ATV ignition is in the “ON” position.

1 - CALIBRATION FILE ID

On the top left corner of the Cannondale Diagnostic Tool main screen there will be a Numeric Cal ID number for the calibration file that is open. If “Untitled” is displayed in this area of the screen, no calibration file has been opened (from a saved file) or received from the vehicle ECU. In addition to the ID number , each cali brati on file i s assigned a 128-chara cter descript ion . Although Cannondale a ssigns a Numeric Cal ID and description to authorized files, a calibration file is like most other kinds of computer files. Its possible to changes to the Numeric Cal ID and description through third party software applications.

Do not experiment with calibration files! Sending unidentified, altered, or third party calibration files can result in severe damage to the vehicle or affect the safe operation of the vehicle. You could be severely injure d or killed in a resulting accident. Always consult the Cannondale website (www.cannondale.com) for calibration files authorized for a specific vehicle identification number (VIN).

The ECU for each ATV and Motorcycle leaving the Cannondale factory is loaded with a specific calibration file. All calibration files developed by Cannondale are assigned a Numeric Cal ID code. Refer to "Numeric Cal ID Coding" starting on page 8. The code identifies the model, and sequence of the calibration file issued. The calibration files SHOULD NOT be interchanged between model VINs or models. A database of calibrations files is maintained on the Cannondale website so that service technicians have ready access to the correct factory authorized calibration files for a particular vehicle VIN. Vehicle’s equipped with a third party (aftermarket) map select interface can toggle maps (and other fueling features) while the engine is running to meet changing performance demands.

2 - OPENING A CALIBRATION FILE

The OPEN Calibration File (saved) button opens the Windows explorer so that you can look for and open a calibration file that is saved on your PC or Pocket PC. A saved calibration file might be one that you have received via e-mail, downloaded from the Cannondale website, or one that is stored on a diskette or CD. This button functions the same way as if you click File - Open.

3 - RECEIVING A CALIBRATION FILE FROM THE VEHICLE ECU

The RECEIVE Calibration File (from ECU) button allow you to receives the calibration file from the vehicle’s ECU to the Cannondale Diagnostic Tool. It works just like opening a saved calibration file, but unlike opening a saved calibration file on your computer the calibration file will be “received” from the vehicle ECU across the data cable.

NOTE :

The received calibration file is not removed from the ECU, it is merely copied into the Cannondale Diagnostic Tool program.

1. Connect the data cable to the computer and vehicle.

2. Open the Cannondale Dia gnostic Tool software on your PC.

3. Power-up the vehicle’s ECU.

4. Click the RECEIVE Calibration File (from ECU) button. After you click the button, the da ta transfer will start. W hile the data is copied fr om the ECU to the PC the

progress indicator in the upper right of the menu will dis play and the LED on the data cable bl ock may appear to flicker. The time required for the tran sfe r co uld v ary. It should take place within 1 minute.

When the entire data transfer process is complete, you will see the “Receive complete” message.

5. Click OK. The vehicle calibration file has now been copied to the Cannondale Diagnostic Tool program.

4-SEND CALIBRATION FILE (TO ECU)

The SEND Calibration File (to ECU) button “sends” the calibration file open (in the Cannondale Diagnostic Tool software) to the vehicle ECU.

Whenever you send a calibration file to the vehicle ECU you have to keep the following points in mind:

• The software will automatically retrieve the vehicle specific variables (throttle positions (min./max), throttle body offset, injector flow rate, injector offset) from the vehicle’s current calibration file (if specific values have not been entered manually) an d send the r etrieved valu es with the op en file. The process is automatic.

• Anytime the throttle body is serviced, you will have to reset or “teach” the ECU the new values before the new calibration file is sent to the ECU. In the case of a replaced throttle body or injector set, you will have to enter the throttle body offset and injector flow rate, and injector offset variable values that are supplied with the components in the main screen before sending the calibration file to the vehicle. Refer to "8 - Updating calibrations" starting on pa ge15.

1. Connect the data cable to the computer and vehicle.

2. Open the Cannondale Dia gnostic Tool software on your PC.

3. Power-up the vehicle. When the vehicle is powered-up, the LED on the data cable block with be lit.

4. Open a calibration file or receive a calibration.

5. Click the SEND Calibration File (to ECU) button. The file that is open will be sent to the vehicle ECU. It will over-write the curren t calibration file store d in the ECU. When the sen d has been completed the vehicle ECU will automatica lly power i tself down . The LED on the data cab le block wi ll turn off indic ating the E CU power is now off. The calibration file just sent will remain “open” in the Cannondale Diagnostic T ool software program until the program is exited or another calibration file is op ened or received.

5- SET THE THROTTLE POSITION

CAUTION

Set the throttle p os i t io n wi th th e ve h icle off.

This SET Throttle Position button enables you to “teach” the ECU the fully closed and fully open throttle body plate positions. Teaching the ECU these positions assures that the ECU is calculating fuel and timing on the information arriving from the Throttle Position Sensor (TPS) mounted on the throttle body. Slight variations in different vehicles necessitate this teaching step. When a calibration file is opened or received, the TPS fully closed and fully open voltage values are displayed at the “TPS Sensor Closed (volts)” and the “TPS Sensor open (volts)” in the main screen.

1. Make sure the throttle plate on the vehicle is completely closed. “Closed” does not mean at the idle position, rather, it means the idle adjustment screw is backed out until the throttle plate is completely shut. Pay attention to any tension present in the cable. Tension will hold the plate open. While you can’t see inside the installed throttle body, checking the position of the throttle set plate position can confirm that the plate is fully closed.

2. Connect the data cable to the computer and vehicle.

3. Open the Cannondale Dia gnostic Tool software on your PC.

4. Power-up the vehicle.

5. Use the OPEN button to open a calib ration file that is save d on your PC, or use the RECEIVE button to open the calibration file that is currently sto red in the vehicle E CU. When the calibrati on file is opened or received su cc es s f ull y, click the SET Throttle Position button. The following promp t will displ ay :

P/N 912-5001985 Printed : 11/8/01

Page 12

6. Since you already made sure the throttle plate was completely closed click OK to continue. Next, the following prompt will display:

7. When the prompt above displays , have an assista nt fully open the th rottle and hold it. W hile the throttle is held in the fully open position click OK. Immediately after you click OK, you will see the following prompt:

8. Tell your as sistant to release the throttle. Click OK and the Cannondale Dealer Tool will send the open calibration file (which now in cludes the new values for fully closed and fully open throt tle) to the vehicle ECU.

When the send is co mpleted, t he vehic le ECU wi ll automa tically po wer itself down - the green LE D on the data cable block will go out. Communication from the software to the ECU is now shut down. To recommunicate with the ECU, you will have to power-up the vehicle once again.

9. Power-up the vehicle ECU and click on the MONITOR ECU Parameters button . You are loo king for the “Throttle (%) Open value.”

Now, make sure the ECU parameters display is in the Continuous mode. Adjust the idle adjustment screw so that the “Throttle (%) Open ” value increase s by 3%. For example , if the value was 2.3 wi th the throttle plate fully closed, you need to adjust this to approximately 5.3 to ballpark the throttle plate position en ough to achieve idle. Start the engine and allow the vehicle to reach operating temperature (70°C) and fine tune the vehicle idle setting as specified for the vehicle.

NOTE :

Refer to "6 - ECU Monitor" starting on page 13.

6 - ECU MONITOR

The MONITOR ECU Parameters button enables you to monitor selected ECU parameters with the vehicle engine running or with the vehicle engine off. It can be operated in “Continuous” (live) or “Hold” (snap shot) mode. You can start the vehicle with the monitor running.

1. Connect the data cable to the computer and vehicle.

2. Open the Cannondale Dia gnostic Tool software on your PC.

3. Power-up the vehicle ECU.

4. Click the MONITOR ECU Parameters button. The ECU monitor w indow will be di splayed. C lick CANCEL to exit and close the monitor.

This displays the engine RPM. This displays the % (percentage) that the

throttle plate is open. This value may not be "0" even with the throttle plate completely closed.

NOTE :

This is the battery (system) voltage.

This is the air temperature reading as measured by the airbox air pressure sensor.

This is the airbox pressure reading as measured by the ECU sensor.

This is engine temperature reading as measured by the coolant temperature senso

This is the position of the Idle Air Control Valve (IACV). The ECU moves or "steps" the valve between 0 - 255 depending on the current engine and air temperature.

Select "Continuous" to view live data Select "Hold" to take a snap shot and hold the values displayed.

While this window is open, con stant communica tions between the ECU and PC are o ccurring - the ECU wi ll not power itself down. The moment you click CANCEL, the two minute power-down timing will start if no other communication is attempted.

7 - RECEIVE FAULTS (FROM ECU)

The vehicle ECU will record and maintain faults that it encounters during operation. The “RECEIVE Fault(s) (From ECU)” button enables you to read the codes the ECU is currently encountering. Most faults reported by the system can be corrected by examining the connector attached to the device or by tracing the continuity between the ECU connectors and the device connector.

NOTE :

Obtain the vehicle’s wiring diagram before attempting any testing.

1. Connect the data cable to the computer and vehicle.

2. Open the Cannondale Dia gnostic Tool software on your PC.

3. Power-up the vehicle. When the vehicle is powered-up, the LED on the data cable block with be lit.

4. Click the “RECEIVE Fault(s) (From ECU)” button. If the ECU is reporting any faults they will be displayed.

8 - UPDATING CALIBRATIONS

Click Cncel to exit

The UPDATE Calibrations button enables you to calibrate the Throttle Body Leakage (also called Throttle Body Offset), the Injector Flow Rate, and Injector Offset. The current values for an open or received ca libration file ar e displayed in the main screen:

These calibrations compensate or corre ct for slight manufactur ing variations i n the vehicle’ s throt tle body and/or fuel injectors. Anytime these components are serviced or changed, these values must be calibrated. The values are loaded to the calibration file when the vehicle is dyno tested and are determined at the factory. The Cannondale Diagnostic Tool enables you to input these calibrations into the calibration file manually. If either the throttle body or fuel injectors are replaced - the variables are supplied by factory analysts and would be packaged with the parts.

1. Connect the data cable to the computer and vehicle.

2. Power-up the ECU.

3. Click the “UPDATE Calibrations” button. The following menu will display.

Type in values and click "OK."

4. Type in the values in the corresponding fields and click “OK.” The new values will display in the main

screen.

5. Now, you have to send these values to the ECU for them to take effect. Click the “SEND Calibration File

(to ECU)” button.

9 - PROGRESS INDICATOR

Whenever data is being transferred between the vehicle ECU and PC a progress indicator displays in the upper right area of the main screen.

Data transfers should take no more than 1 minute. If the progress indicator freezes for a long time, close the Cannondale Diagnostic Tool software and try again making sure the cables are connected properly and that the vehicle battery is fully charged.

RETRYING CHECKSUM

Data is transferred between the vehicle and PC in small “packets” or chunks. During the transfer process, checks are performed by the diagnostic tool (software) to ensure that the data is not damaged during the transfer. Each small packet is checked during the transfer. If data errors are detected in the packet the message “Retrying Checksum...” will display in the progress indicator:

Retryin Checksum . . .

Typically, this is due to electrical “noise” or other interference during the process. The diagnostic tool will keep trying automatically.

10 - VERSION INFORMATION

The Cannondale logo in the top right corner of the main menu is a link to the Cannondale Tech Center website. The site includes all factory issued calibration files. The file can be downloaded via the link. Follow the link for more details.
