194001438 - E3030 DEMISTING REARSCREEN AND REAR VIEW MIRRORS - FUNCTIONAL DESCRIPTION (RIGHT HAND DRIVE)

The heated rear windscreen relay T11, located in the junction unit under the dashboard B002, controls the simultaneousl engagement of the heated rear windscren P055 defrosting function - line protected by fuse F40 - and the defrosting resistances for the screen washer jets O050 and O051 - line protected by fuse F41.The coil for relay T11 receives an ignition operated power supply (INT/A from the steering lock contro lunit) and is energized by an earth coming from the Body Computer M011 pin 6 of connector F; this signal is sent according to a control logic described previously and, if there is an earth signal at pin 32 of connector G of M001 coming from the heated rear windscreen button or from the MAX-DEF function. This signal comes from the climate control system control unit M070 (for versions with manual climate control from pin 14 of M070; for versions with automatic climate control, from pin 4 of connector A), to which the signal for switching on the LED is sent from pin 21 of connector H of M001 (for versions with manual climate control only).Control units M066 and M067 receive a supply - at pin 11 of connector D - from the line protected by fuse F32 of underfacia control unit B002 .On the basis of the complex control logic illustrated previously, the engagement command for the defrosting is sent via the CAN to the two door control units as well which control the resistances located in mirrors P060 and P061 from pins 7 and 9 of connector E of M066 and M067.
