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 Diagnostic 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.

NOTE :

The Fault Report window sample above was taken while the Cannondale Diagnostic Tool was connected to an

2002 X440s motorcycle. This vehicle does not have a cooling fan. The “Cooling Fan open fault” will report when

the tool is connected to a motorcycle, however, it can be disregarded. Also for the sample fault report above, we

temporarily disconnected the air temperature sensor - notice the “Air temp sensor high fault” that was reported.
