INSTRUMENT PANEL FUNCTIONAL DESCRIPTION

2.0 16V JTD, 2.2 16V JTD · MY 2005

The management of the warning lights and the information shown by the display is entrusted to the milometer warning lights node M140 and to the instrument panel node E050 which receive information from the control units involved via the CAN.

As well as these two nodes the multifunction screen node M172 incorporated in the DT colour screen is also included.

See E4090 NAVIGATOR

Control units E050 (pin 13) and M140 (pin 4) receive power from body computer node M001 (pin 6 connector D) with one line protected by fuse F14.

Odometer warning light node M140 (pins 2,5), instrument panel E050 (pins 6, 12) and body computer node M001 (pin 8, 10 connector D) communicate via the CAN network.

See E1050 CAN CONNECTION LINES

Body computer node M001 (pins 21, 23 connector L) communicate with airbag control unit M060 (pins 33, 30 respectively), they also (pin 5 connector F) supply it with power (pin 47).

The following are also connected to body computer node M001:

- handbrake engaged switch I040 (pin 2) to pin 35 of connector L;

- driver side seatbelt switch I046 (pin 2) to pin 37 of connector L;

- fuel pump and level gauge N040 (pins 5 and 6 respectively) to pins 14 and 15 of connector E;

- engine coolant level sensor K026 (pin 2) to pin 14 of connector G;

- multifunction screen node M172 (pin 1) to pin 1 of connector D;

- the multiple diagnostic connector system to pins 8 and 10 of connector G.

See E8010 DIAGNOSTIC MULTIPLE CONNECTOR

Pins 3 and 4 of the electric fuel pump and level gauge N040 are connected to the electronic ignition and injection system.

See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT

Pin 3 of coolant level sensor K026 is connectedto engine compartment junction unit B001 (pin 20 connector F) via a line protected by fuse F06.

The following are also connected to engine compartment junction unit B001:

- low engine oil pressure sensor K030 (pin 2) to pin 20 of connector B;

- engine oil level sensor K032 (pins 1, 2, 3 respectively) to pins 7, 22, 6 of connector B.

The information received from B001 is sent (pins 11, 12 connector F) to body computer node M001 (pins 2, 4 connector E) via the CAN network.

Body computer M001 (pins 25, 27 connector E) communicates via the CAN network with ABS control unit M050 (pins 15, 26), which in turn communicates (pin 14, 25) with engine control unit M010 (pins A3, A4 connector A).

In versions with an ESP device, control unitM050 communicates with engine control unit M010 via pins14 and 35.

Engine coolant temperature K036 (pins 2, 1 respectively) is connected to engine control unit M010 (pins D1, E1 connector B).

The following are supplied to ABS/ESP control unit M050:

- pad wear sensors for left brake K020 and right brake K021 (pin 1 connector A) at pin 22;

- signal for brake fluid sensor K025 (pin 1) at pin 21 (or pin 17 in versions with ESP).

Multifunction screen node M172 (pins 7, 9) communicates with instrument panel E050 (pins 6, 12) via the CAN line.
