DescriptionA control system supervises and governs the operation of the manual gearbox via an electrohydraulic device to create a robotised gearbox system.The system operates in two modes: SEMIAUTOMATIC MODE (MANUAL): the driver manages gear engagement via the lever located on the tunnel. AUTOMATIC MODE (AUTO): the decision to change gears is delegated to the electronic system, in accordance with two strategies, the first aiming for driving comfort (NORMAL), the second aiming to limit fuel consumption (ECO).The electronic control unit communicates with the engine management control unit via the CAN network and two dedicated lines, one for the engine rpm signal and one for diagnostics.The control unit drives, by means of a complex operating logic, an electrohydraulic unit located on the gearbox, via a specific electric pump. For more details, Characteristic of working principle 2127 ELECTRO-HYDRAULIC SELECTION. GEARBOX EXTERNAL. CONTROLS . The supply lines to the control unit and the various system components (sensors and actuators) are protected by two fuses located in the engine compartment control unit. Control unit self-diagnosis notifies of the onset of these faults via a special warning light in the instrument panel: The robotised gearbox control unit sends the instrument panel information on the speed engaged. This is shown on the display. For more details, Characteristic of working principle 2127 ELECTRO-HYDRAULIC SELECTION. GEARBOX EXTERNAL. CONTROLS .
Functional description The automatic transmission control unit M54 controls and governs the entire gearbox management system.The direct supply for the control unit arrives from the battery, from the line protected by fuse F23 of engine bay control unit The supply controlled by the ignition (15/54) reaches pin 28 from connector A of M54 from the line protected by fuse F16 of the engine compartment junction unit B1. Pins 1 and 2 of connector A of M54 are earthed. A set of sensors and potentiometers on the gearbox informs the gearbox as to which gear is engaged: the potentiometers are supplied from pin 73 of the connector B; pin 66 provides the reference earth: the gear selector potentiometer K68 provides a signal to pin 51 of connector A; the gear engagement potentiometer K69 returns a signal to pin 39 of connector A; the hydraulic unit oil pressure sensor K96 returns a signal to pin 40 of connector A. Pins 38 and 50 of connector A M54 are connected to the car speed sensor (gearbox output) K78 . The gear control unit H37 is connected to the control unit M54 and receives a reference earth from pin 65 of connector B of M54. These signals are sent to pins 67, 74, 68 of connector B and pin 26 of connector A of M54; Clutch sensor K91 is connected to pins 34, 35, 46, and 47 of connector A of M54 . The mode selection button is located in tunnel switch unit H35 and connected to control unit M54 at pin 77 of connector B. The steering wheel controls - connected via clock spring contact D47 , send signals to pin 75 of connector B of M54 ; a reference earth is received from pin 65 of connector B. Pin 69 of connector B of M10 receives the signal coming from the brake lights switch I30 , with the supply controlled by the ignition (INT) from fuse F37 of underfacia junction unit B2 (). In accordance with the operating logic, the control unit controls the electrohydraulic unit located on the gearbox which effects the gear change: the electric pump N47 , which keeps the oil in the hydraulic unit under pressure, is controlled from pin 31 of connector A. The pump N47 is controlled by a specific relay J87 (supplied by the line of fuse F5 of the engine compartment junction unit B1).The control unit then controls the opening of the hydraulic unit solenoids:the two gear engagement solenoids L51 and L52 are controlled from pins 32 and 44 of connector A of M54 ;Gear selection solenoid L53 is controlled from pin 29 of connector A of M54 ;the clutch control solenoid L56 is controlled from pin 43 of connector A of M54 . A safety signal comes from pin 42 of connector A of M54 for the starting enablement relay (pin 50 of the starter motor A20 ); the signal requesting starting reaches pin 76 of connector B 3360943SeeE5010STARTING AND RECHARING . The control unit M54 also manages the door open buzzer: the driver's door open signal - catch N50 - reaches pin 78 of connector B of M54 ; The control for the buzzer E47 , located in the glove compartment, leaves pin 80 of connector B. The buzzer is supplied by the line protected by fuse F23 of the engine compartment junction unit B1 . Self-diagnostic data can be read by connecting the unit to connector C of Body Computer M1 - pin 7: this receives signals from pin 49 of connector A of M54 . (the line is shared with the engine control unit M10 via the relevant tester line). 3361166SeeE8010DIAGNOSTIC MULTIPLE CONNECTOR Signals for the gearbox failure warning light in instrument panel E50 , and the instrument gear indication display, are sent via the CAN network - pins 33 and 45 of connector A of M54 . The speedometer signal is downloaded via the CAN network. Pin 48 of connector A is connected to engine management control unit M10 , from which it receives an engine rpm signal.
