Tank venting diagnostics (OBDII)

The Trionic sends a signal to the main instrument unit on the diagnostic status of the tank venting system. If there is leakage in the venting system, the main instrument unit sends the information "Tighten fuel filler cap ON" on the bus. The SID unit then displays the requested message.
