244001764 - E3040 CENTRAL LOCKING OPERATIONAL DESCRIPTION
Operational Description
ABI control unit (electric window/door lock) M135 manages the vehicle door lock/release system. The control unit is supplied:
directly from the battery: via a connection between pin 8 connector B of M135 and pin 11 connector B of optional junction unit B101, protected by fuse F38, housed in optional junction unit B101;
key operation: via a connection between pin 7 connector B of M135 and pin 3 connector C of optional junction unit B002, protected by fuse F35, housed in optional junction unit B002;
Control unit ABI M135 receives and sends the following signals from connector B:
pin 15 : input from short-circuit junction D097G - pin 6 - of door lock signal;
pin 16 : input from short-circuit junction D097F - pin 6 - of door lock release signal;
pin 5 : send door lock control signal to short-circuit junction D097G - pin 1;
pin 4 : send door lock release control signal to short-circuit junction D097F - pin 1;
pin 13 : connection to earth C015.
Short circuit junction D097G manages the door lock signal. The closure control is received at pins 8 and 7 from front door locks N050 and N051 respectively - pin 4 -. Pin 1 receives a door lock signal from control unit ABI M135 that distributes to door locks N051 and N050 respectively from pins 2 and 3.Short circuit junction D097F manages the door lock release signal. The opening control is received at pins 8 and 7 from front door locks N050 and N051 respectively - pin 3 -. Pin 6 receives a door lock release signal from control unit ABI M135 that distributes to door locks N051 and N050 respectively from pins 2 and 3.Front door locks N050 and N051 are connected as follows:
pin 5 : earth connection C020;
pin 3 : earth signal transmission for door lock;
pin 4 : earth signal transmission for door lock release;
