Hi Randy
To ensure that we see the correct details (ECU info/bike details/fault codes), always add a full autoscan of your bike to your threads, you can run an autoscan and select download, this will provide it in a text format to copy paste.
Regarding the fault code, the description from the service manual is as follows:
The electronic immobiliser EWS control unit detects a short circuit of the fuel filler cap switch.
And the suggested service plan:
Check wires, wiring harness and plug connectors to the fuel filler cap switch.
Check the plug connection between wiring harness and EWS.
Check fuel filler cap switch.
Kind regards
Ruan
