This is a Technical Journal: "BLIS service required" may be displayed in DIM(Drivers Information Module) intermittently during start, without any corresponding DTC's set. This may occur if the BLIS camera heating element is broken due to a hot spot, or if the lead cable for the heater element has become loose due to a bad soldering. Start the engine and make sure that the ambient temperature is below 28ºC (82ºF) to activate the heater function. Test the heater element function by touching the BLIS camera lens with your finger, or spray ice spray to see if the ice disappear. If there is no heat detected, then remove the mirror from the car and access the heater element for inspection. * If there is a visible hot-spot on the heater element, or a loose lead cable, replace the heating element according to VIDA instructions.
