DescriptionIn the case of poor visibility, it is possibleto activate demisting of the rear windscreen and the door mirrors.The heating resistances for thesecomponents absorb a considerable amount of energy and they are thereforechecked and deactivated after a certain period: the defrosting istimed, according to the following logic, managed by the Body Computer:ignition ON (INT/A);activation signal from the relevant button, located onthe climate control system control panel.In these circumstances the resistances remainsupplied for a maximum of 20 minutes, then the power supply is cutoff.The power supply is also cut offunder the following conditions:ignition in OFF positiondeactivation signal from the relevant button;battery voltage below 8.5 Vafter the first 10 minutes operation, if the engine speedis below 1000 rpm.When the demister is on, a warning lighton the climate control system control unit is activated.
Functional description The heated rear windscreen relay T11,located in the underdashboard junction unit B2, controls the simultaneousactivation of the defrosting function for both the heated rear windscreenP55 and the resistances located in the mirrors P60 and P61 via thelines protected by fuses F40 and F41, respectively of junction unitB2. The supply for the coil for relay T11is 'controlled by the ignition' (INT/A) and is energized by an earthsignal coming from the Body Computer M1 - pin 6 of connector F; this signalis sent according to the complex control logic described previouslyand, in particular, when a signal arrives - at pin 32 of connectorG of M11 - from the heated rear windscreen button. This signal comes from climate control unit H80 ,which receives the feedback signal for activation of the relevantled - from pin 21 of connector H of M1 -.
