DF055 Coded line circuit - 1999 Megane 1.6 - immob locked

[tldmobilerepair]

Does anyone have a wiring diagram available for the immobiliser system on this vehicle as we have no immobliser light being shown on the dash at all and live data shows the ecu is locked, immobliser is active and throwing up the fault code DF055 Coded line circuit

Thanks in advance
