INSTRUMENT PANEL - Functional description

1.1, 1.2 8v

Functional description

The instrument panel comprises two separate connectors, each of which implements the following functions:

Connector A:

• pin 1: ignition-dependent supply, provided by the body computer node M001; the line is protected by the fuse F51, housed in the junction unit under the instrument panelSee E1010 SUPPLY;
• pin 3: direct battery supply, provided by the body computer node M001; the line is protected by the fuse F01, housed in the engine compartment junction unit B001 See E1010 SUPPLY;
• pin 2: reference to earth C020 connector B;
• pin 7: receives the supply for the headlamp adjustment controlsSee E3080 HEADLAMP AGLINMENT CORRECTOR; the line is protected by the fuse F13, located in the body computer node, operated by a relay integrated in the control unit;
• pin 6: sends the command to the headlamp adjustment motorsSee E3080 HEADLAMP AGLINMENT CORRECTOR;
• pin 4: sends the signal for the Trip computer functionSee E4080 TRIP COMPUTER;
• pins 8, 9: connection to the CAN networkSee E1050 CAN CONNECTION LINES;

The earth C020 is secured to the floor, and is positioned near the front right wheelarch (foot area).

Connector B:

• pin 13: management of Air Bag system fault warning lightSee E7030 AIRBAG;
• pin 14: management of passenger Air Bag deactivation warning lightSee E7030 AIRBAG;
• pins 17, 18: connection with the external air temperature sensor, contained in the left rearview mirror P060 See E3032 DOOR MIRROR ADJUSTMENT;

The warning lights (side lights, dipped beam, main beam, etc.) are managed directly by the instrument panel E050, in accordance with the data received via the CAN network from the body computer node M001.

The body computer node, via the CAN network, also sends:

• the signal coming from the speedometer sensor K084, for managing the speedometer;
• the signal coming from the fuel pump N040, for managing the fuel gauge;
• the signal coming from the switch I040, for displaying the 'handbrake on' warning light
• the signal coming from the sensor K025, for displaying the 'low brake fluid level' warning light

The engine control unit M010 communicates to the body computer node the signals supplied by the engine rpm sensor K046 and the water temperature sensor K036. These signals are then sent to the instrument panel E050, for managing the rev counter and water temperature gauge.
