DESCRIPTION - REVERSING LIGHTS - Alfa Romeo 159 2.4 JTD 20V Fino a 12/05
The vehicle is equipped with a white reversing light located in the right rear light cluster on the moving part of the boot lid.It is activated each time reverse gear is engaged: this information arrives from the automatic transmission control unit. The circuit for the reversing lights receives a power supply with the TEG inserted (INT) and is protected by a dedicated fuse in the junction unit under the dashboard.The signal that reverse gear has been engaged is managed by the Body Computer which forwards this information to the steering column switch unit for the automatic operation of the rearscreen wiper and, via the CAN, to the other nodes, for example to the parking sensors control unit.
FUNCTIONAL DESCRIPTION - REVERSING LIGHTS - Alfa Romeo 159 2.4 JTD 20V Fino a 12/05
The switch for the reversing lights I20 receives a supply controlled by the ignition (INT) from the fuse line F35 of the junction unit under the dashboard B2.When reverse gear is engaged, the automatic transmission control unit M55 sends the reverse gear engaged signal from pin 13 of connector A to relay T20 in the engine compartment junction unit B1, which sends the power supply to the reversing light in the right rear light cluster, moving section, F36, directly via junction unit B2, from pin 7 of connector D.The activation signal for the reversing light is also sent to the Body Computer M1 - pin 3 of connector F - and from there to the steering column switch unit H5, for the automatic engagement of the rearscreen wiper.
