refrigerant temperature and the signal "engine temperature too high" when ignition is switched on (data
telegram). If the refrigerant temperature is too high information cannot be transmitted.
◆ The assignment of the ignition key can only be recognised and therefore transmitted by the dash panel insert
on vehicles fitted with an immobiliser.
