Reversing Lights

DESCRIPTION 

The vehicle is equipped with a white reversing light located at the right back side.

Reverse gear can only be engaged by pressing the dedicated "R" button on the central tunnel, with the brake pedal pressed.

The reverse engagement signal is sent to the engine management control unit and the automatic transmission control unit and from this, via the CAN, to the Body Computer which switches on the lights in question and also controls the operation of the parking sensor control unit.

FUNCTIONAL DESCRIPTION 

• The Body Computer M001 - connector A - receives a direct power supply from the battery through the line protected by maxi fuse F01 of the engine compartment control unit B001.
• The Body Computer M001 receives an ignition-controlled power supply (INT) at pin 11 of connector E: this signal is used, amongst other things, to "wake up the network".
• The ground reference reaches pins 9, 10 of connector E of Body Computer M001.
• Once the brake pedal switch I030 has been pressed, the signal reaches the twin clutch automatic transmission control unit M196, the engine management control unit M010 and the Body Computer M001, via the CAN.
• Only at this moment, the reverse engagement is enabled by pressing the "R" button for the twin clutch automatic transmission gear selector control unit M195.
• The reverse engagement control reaches pin 33 of connector A of the twin clutch automatic transmission control unit M196.
• The Body Computer M001 controls the power supply of the reverse rear light cluster F033 from pin 45 of connector C.
• The "R" symbol will be displayed on the instrument panel E050 and the buzzer will activate.
