DescriptionIf the visibility is poor it is possible to activate the defrosting of the rearscreen, the external rear view mirrors and the windscreen washer jets: the control button is located in the climate control system control unit and the command is sent to the Body Computer via the CAN.The heating resistances for these components absorb a considerable amount of energy and they are therefore checked and deactivated after a certain period: the defrosting is timed, according to the following logic, managed by the Body Computer:ignition ON (INT/A);activation signal coming from the relevant button (or from the 'rapid demist' function for the actual air conditioner).In these circumstances the resistances remain supplied for a maximum of 20 minutes, then the power supply is cut off.The power supply is also cut off under the following conditions:ignition in STOP position;disengagement signal from the button (or from the 'rapid demisting' function);battery voltage below 8.5 Vafter the first 10 minutes operation, if the engine speed is below 950 rpm orWith the defrosting function on the warning light, in the climate control system control unit, connected to the Body Computer via the CAN, also comes on.The control logic also intervenes at the MAX-DEF command from the climate control: the defrosting function is activated for a maximum time of 7 minutes (the deactivation of the MAX-DEF control only causes the heated rear windscreen to be switched off if the command to turn it on came from the MAX-DEF; if, on the other hand, the command came from the heated rear windscreen button, it remains on;The defrosting circuit is controlled by the heated rear windscreen relay and is protected by two fuses, one for the rearscreen and the other for the other resistance, all housed in the underdashboard control unit.
Functional description The heated rear windscreen relay T11, located in the underdashboard control unit B2 , controls the simultaneous activation of the defrosting function for both the heated rear windscreen P55 - line protected by fuse F40 - and the external rear view mirrors P60 and P61 and the defrosting resistors for the rearscreen washer O50 and 051 - line protected by fuse F41. The supply for the coil for relay T11 is 'controlled by the ignition' (INT/A) and is energized by an earth signal coming from the Body Computer M1 - pin 6 of connector F; this signal is sent according to the complex control logic described previously and, in particular, when a signal arrives, via the CAN, coming from the climate control system control unit M70 (heated rear windscreen button pressed or MAX-DEF function on); the feedback signal for lighting up the LED is sent to the control unit M70 via the CAN line. The low outside temperature signal, which switches on the automatic defrosting, detected by a sensor inside the external rear view mirror P60 , also reaches the control unit in the door H44 via the CAN line.

Follow these precautions.769On batteries with an opticam hydrometer,electrolyte level and battery charge status can be monitored qualitativelyby examining the indicator colour: a light, bright colour indicates low electrolytelevel: top up with distilled water;a dark colour without a green area in thecentre indicates that the electrolyte level is correct but chargeis low: recharge the battery; a dark colour with a green area in themiddle indicates that both electrolyte level and charge status arecorrect: no action is necessary. For further details, see DESCRIPTION ANDOPERATION - 5580.768Proceed as follows.Check the battery voltage without loadusing the test device recommended by the Service outlets (e.g. 'MICRO360'). Depending on the voltage values measured,which define the state of charge of the battery, proceed as follows:If the voltage without load is less than12.10 V, replace the battery (see op.). 5530B10).If the voltage without load is over 12.10V but less than 12.50 V, recharge the battery (see op. 5530B14).If the voltage without load is over 12.50V, the battery is efficient.If necessary, top up the electrolyte asfollows.Carefully remove the cap strip.Top up with distilled and deionized water,taking care not to allow electrolyte to splash out.768
