ECU DIAGNOSTIC FAULT CODES

The X10 ECU (later version date code 091001) has the ability to conduct continuous diagnostics on the EFI system. If there is a fault in one of the sensors the ECU will flash a fault code to the FI Warning light. Not all models have a FI warning light but most will have this as a accessory workshop diagnostic tool that can be plugged into the standard wiring harness. Vortex is also developing an accessory FI Light as a separate product.
