E4010 INSTRUMENT PANEL FUNCTIONAL DESCRIPTION

Engines: 2.0 16V, 2.0 JTD 8V, 2.3 JTD 16V, 2.8 JTD 8V

Operational Description

The control panel is ignition-operated from a line protected by fuse F37, housed in under-facia junction unit B002, and receives a direct battery supply from control panel H090 - pin 16 connector B - from a line protected by fuse F01, housed in engine bay control unit B001. The earth connection is guaranteed by the connection of pin 4 connector A to earth C015 - pin 1 -.The instrument panel is made up of five different connectors, each of which implements the following functions:Connector A:

pin 1: speedometer output signal for the engine management control unit M010 - pin 49 connector D -; for the 2.0 petrol versions the signal reaches control unit M010 at pin G2 connector A;
pin 2: water in diesel filter warning light control from sensor K031 - pin 2 or, for vehicles with a Green Filter, the diesel pre-heating resistance O020 - pin 1 connector B;
pin 3: Code system fault warning light management;
pin 4: earth reference C015;
pin 5: speedometer sensor earth reference K084 - pin 2 -;
pin 6: handbrake on warning light control from switch I040;
pin 7: injection system/EOBD fault warning light control;
pin 9: engine coolant temperature signal input, coming from sensor K035 - pin 2 -; for the 2.0 petrol versions, the signal is supplied by sensor K036, pin 3;

Connector B:

pin 1: alternator recharging warning light control;
pin 2: brake pad wear warning light control from sensor K020 - pin 1 -;
pin 3: low brake fluid level warning light control from sensor K025 - pin 1 -;
pin 4: glow plug preheating warning warning light control;
pin 5: right turn signal warning light control;
pin 6: left turn signal warning light control;
pin 7: low engine oil pressure warning light control from sensor K028 - pin 1 -;
pin 8: Air Bag system failure warning light control;
pin 9: side light on warning light control;
pin 11: engine oil level input from sensor K032 - pin 1 -:
pin 12: earth reference to sensor K032 - pin 3 -;

Connector C:

pin 1: doors open warning light control;
pin 3: doors open warning light control;
pin 6: automatic transmission input;
pin 7: ABS fault warning light control;
pin 8: EBD fault warning light control;
pin 9: Cruise Control system warning light control;

Connector D:

pin 10: battery supply;
pin 11: high beam warning light control;
pin 12: ignition-operated power supply;
pin 13: fuel level sensor earth reference N041 - pin 2 -;
pin 14: input signal from fuel level sensor N041 - pin 1 -;
pin 15: input signal from speedometer sensor K084 - pin 3 -;
pin 16: engine coolant overheating warning light control, coming from sensor K035 - pin 1 -; for versions with automatic transmission the signal is supplied by the automatic transmission control unit M055; for the 2.0 petrol versions, the signal is supplied by the engine management control unit M010, pin K3 connector (see wiring diagram E5030 - PETROL ENGINES ELECTRONIC MANAGEMENT);
pin 17: signal input for rev counter;
pin 18: coolant level warning light control from sensor K026 - pin 2 -;

Connector E:

pin 11: speedometer signal output;
pin 13: speedometer signal output;
pin 14: speedometer signal input;
pin 15: ASR system fault warning light control;
pin 16: seat belts unfastened warning light control;
pin 17: passenger Air Bag deactivation warning light control.

On versions for the Arab market, the seat belt control unit M048 fitted has a dual function: to signal that a seat belt is not fastened (driver''s only) and that the speed limit of 120 km/h has been exceeded by means of an auditory warning.The above control unit receives a power supply at pin 2 along the line protected by fuse F37; pin 12 receives the seat belt not fastened signal from the seat belt warning lights switch I045; it operates the switching on of the seat belt not fastened warning light from pin 3 and receives the speed signal at pin 4 from the instrument panel E050; pin 1 is earthed.
