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.2.4 JTD 10VPins 59 and 54 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 engine management control unit M010 distributes the brake pedal pressed signal to the other control units installed on the vehicle via the C-CAN line, pins 28 and 29 connector A.The discrete speedometer signal is sent, from pin 16 of the braking control unit M051, to the Body Computer M001, pin 7 connector A.( < R1 > ); this signal is also transmitted via the C-CAN from pins 1 and 2 of the braking control unit M051. See E4010 INSTRUMENT PANELThe braking control unit M051 is connected (from pins 1 and 2), via the C-CAN line, to the engine management control unit M010 (pins 28 and 29 connector A). The latter is connected, via C-CAN signals, from pins 9 and 10 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 E050 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.2.4 JTD 20VPins 17 and 80 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 engine management control unit M010 distributes the brake pedal pressed signal to the other control units installed on the vehicle via the C-CAN line, pins 61 and 62 connector A.The discrete speedometer signal is sent, from pin 16 of the braking control unit M051, to the Body Computer M001, pin 7 connector A.( < R1 > ); this signal is also transmitted via the C-CAN from pins 1 and 2 of the braking control unit M051. See E4010 INSTRUMENT PANELThe braking control unit M051 is connected (from pins 1 and 2), via the C-CAN line, to the engine management control unit M010 (pins 61 and 62 connector A). The latter is connected, via C-CAN signals, from pins 83 and 84 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 E050 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.
