FUNCTIONAL DESCRIPTION

The services relay T13, located in the junction unit under the dashboard B2, supplies pin 14 of connector F, the two control units for the driver''s door M66 and the passenger door M67, pin 8 of connector D, through the control logic described above and controlled by the Body Computer M1, via two lines protected by fuses F47 and F48. Pins 19 of connector B and 7 of connector D of M66 and M67 are earthed. Control units M66 and M67 are connected via the CAN line to one another and to the Body Computer M1.Unit H44 contains the driver and passenger side window controls:: dedicated analogue signals are sent to pins 31 and 32 of connector A of M66 (pin 33 supplies a reference earth).. Similarly, the control at the passenger front door H50 sends a special analogue signal to the control unit M67 pin 32 (pin 33 provides the reference earth).Control unit M66 operates the motor N60 (driver''s side) directly - pins 9 and 10 of connector D - and via control unit M67 - pins 9 and 19 of connector D - motor N61 (passenger side).Pins 2 and 5 of connector C of M66 and M67 also receive signals from the anti-crush safety sensors K22 and K23 .The two control units are connected to the instrument panel E50 via the CAN line to manage the signal if there is a failure in the anti-crush safety sensors.
