2753520 - E3030 HEATED REAR WINDSCREEN AND DOOR MIRROR DEFROSTING - Functional description

Functional description

The demisting command for the heated rear windscreen and the door mirrors is sent from the special button inside the control panel H090. The body computer node M001 receives the negative signal (with reference to earth C020 connector B) at pin 6 connector N.

Earth C020 is fastened to the passenger compartment floor and is located near the right front wheel arch (footwell area).

Having received the signal, the body computer node:

• from pin 1 connector E: supplies the internal resistance for the heated rear windscreen P055;
• from pin 1 connector M: supplies the internal resistances for the door mirrors P060 and P061.

The supply line for the internal resistances for the door mirrors is protected by fuse F40 which is managed by a relay incorporated in the body computer node.

A special warning light in the instrument panel E050 signals that the function has been switched on. Communication between the body computer node M001 and the instrument panel E050 takes place via the CAN (for further details see wiring diagram E1050).

Door couplings D030 and D031 are housed in the lower part of the pillar (right or left depending on the coupling involved), near the door cable duct.
