FUNCTIONAL DESCRIPTIONThere is a single (earth) signal sent by the steering column switch unit H005 to the Body Computer M001 that manages the left and right direction indicators: from pin 1 of H005 to pin 51 of connector D of M001; the signal sent is coded by means of resistive dividers so that multiple information can be sent by the steering column switch unit to the Body Computer via a single connection. The reference earth reaches pin 10 of H005 from pin 34 of connector D of M001. The (earth) signal for activating the hazard warning lights reaches pin 7 of connector D of M001 from the control button in unit H90, pin 3; pin 6 of H90 receives the reference earth from pin 49 of connector D of M001. . The Body Computer M001 - connector A - receives a direct powr supply from the battery through the line protected by maxi fuse F01 of the engine compartment junction unit B001. The Body Computer M001 receives an ignition-controlled power supply (INT) at pin 11 of connector E. Pin 9 of connector E of M001 provides the Body Computer with a reference earth. The Body Computer M001 controls the side direction indicators F020 (left) and F021 (right) from pins 11 and 9 of connector B, the front direction indicators F010 (left) and F011 (right) from pins 10 and 8 of connector and, lastly, the rear direction indicators F030 (left) and F031 (right) from pins 1 and 3 of connector F. The Body Computer M001 is connected, via the CAN line, to the instrument panel E050 to manage the direction indicator warning lights, the buzzer and, if there is a problem in the circuit, the lights failure warning light. |
