Similarly, the control on front passenger door H50 sends an appropriate analogue signal to control unit M67 pin 32 (pin 33 supplies a reference earth)., which controls motor N61 . Pins 2 and 5 of Connector C of M66 and M67 receive signals from antipinch sensors K22 and K23 . The two control units are connected, via the CAN line, to the instrument panel E50 to manage the general failure warning light if faults are detected in the anti-crush sensors. The aerial-receivier P93 sends the Body Computer M1 the signal to open/close the doors and also windows and sunroof, by connecting to pins 21 and 31 of connector B  See E3040  CENTRAL LOCKING .
