The braking control unt M051 is supplied directly by the battery (at pins 12 and 25) by the lines protected by fuses F02 and F04 of the engine compartment junction unit B001.The supply controlled by the ignition (INT) reaches pin 23 via the line protected by fuse F42 of the junction unit under the dashboard B002.The control unit is earthed at pins 11 and 24.The four sensors K070, K071, K075 and K076 send the speed signals for each wheel to the braking control unit M051 at pins 19, 20, 7, 8, 21, 22, 9 and 10, respectively.Pins 26 and 27 of connector A of the engine management control unit M010 receive the brake pedal pressed signals coming from the N.C. and N.A. contacts of the brake lights switch I030, respectively, with the supply controlled by the ignition (INT) from the lines protected by fuses F35 and F37 of the junction unit under the dashboard B002.The discreet speedometer signal is sent, from pin 16 of the braking control unit M051, to the Body Computer M001, pin 7 connector A; this signal is also transmitted via the C-CAN from pins 1 and 2 of the braking control unit M051.The braking control unit M051 is connected (from pins 1 and 2), via the C-CAN line, to the engine management control unit M010 (pins 12 and 29 connector A). The latter is connected, via C-CAN signals, from pins 45 and 61 connector A, to the Body Computer M001 (pins 32 and 33 connector B) which communicates the management of the ABS warning light to the instrument panel and, if the problems also involve the EBD function, the insufficient brake fluid and handbrake warning light, and manages the display of the failure message..Engine management unit M010 distributes the brake pedal depressed signals to the other control units on the vehicle via the C-CAN line, pins 12 and 29 connector A (for 3.0 bz and 2.4 bz versions) and 61 and 62 (for the 2.4 JTD 20 V version).
