184001924 - E2020 DIRECTION INDICATORS/HAZARD WARNING LIGHTS - FUNCTIONAL DESCRIPTION

Operational description

The direction indicator (earth) activation signals are sent to pins 7 of connector I and 30 of connector G of the Body Computer M1 from the steering column switch unit H5.The hazard warning lights activation signal, on the other hand, reaches pin 34 of connector G of M1 from the control button in the climate control system controls H80 (or M70)The direct power supply for the climate control system controls H80 (or M70) arrives via the line for fuse F39 of the junction unit under the dashboard B2; pin 7 of connector A is earthed (earth controlled by the Body Computer M1).The Body Computer M1 receives a direct specific power supply for the hazard warning lights via the line for fuse F53 of the junction unit under the dashboard B2; as a result, it controls the side direction indicators F20 (left) and F21 (right) from pins 2 and 13 of connector D, the front direction indicators F10 (left) and F11 (right) from pins 38 and 39 of connector B and the rear direction indicators F30 (left) and F31 (right) from pins 12 and 3 of connector D.A (positive) signal is sent from pin 29 of connector G of M1 to switch on the LED in the button in the climate control system controls H80 (or M70)The Body Computer M1 is connected, via the CAN line, to the instrument panel E50 to manage the "direction indicator" warning lights, the buzzer and, if there is a problem in the circuit, the "lights failure" warning light.
