Background
When the ECU is connected to your PC for the first time, Windows detects the ECU and will ask for a device driver. If Windows cannot find a driver for the device and you click the default "Finish" button or click on "Disable the device," then Windows lists the ECU as a "USB Device" under "Other devices" and Windows will never prompt you again to install the driver. If this happens then KManager will not be able to communicate with the ECU.
When installing in Windows XP, Microsoft issues a warning that the software "has not passed Windows Logo Testing to verify its compatibility with Windows XP." If you choose to stop installation here, then Windows lists the ECU as a "USB Device" under "Universal Serial Bus Controllers."
Hints
| • | Most problems are caused by plugging in the ECU before installing the software. Unplug the ECU, install the software, then follow the instructions below to update the drivers. |
| • | Plug the ECU directly into the laptop/computer, not via a USB hub. Some USB hubs cannot supply enough power for the ECU. |
| • | Under Windows 2000, you must be logged in as Administrator or have sufficient privileges to install device drivers. |
Trouble Shooting Procedure
1. First try reinstalling the USB drivers from KManager, under the Help menu.
2. Open the System Properties. To do this right click on My Computer and select Properties, or press <Windows Key> and <Pause/Break>.
3. Open the Device Manager.
4. Click on the + to the left of Universal Serial Bus controllers to show the USB devices connected to the computer. There should be an entry Hondata K-Series ECU.
4. If there is a yellow icon next to the entry for Hondata K-Series ECU, then the USB drivers are not properly installed. Right click in Hondata K-Series ECU and select Update Driver... Follow the instructions as per installing the USB drivers.
5. After the drivers are updated, the yellow exclamation mark should disappear from next to 'Hondata K-Series ECU'.
If you still have problems with the USB driver, reboot into safe mode, open the device manager and remove all copies of 'Hondata K-Series ECU' and any other unknown devices.
