9000 L4-1985cc 2.0L DOHC Turbo EFI (1987)
The lamp in the centre (central warning) lights up the contour of the car in the pictogram and will always light up whenever a fault is indicated.
The coil of every relay has two windings through which the corresponding lighting circuit is supplied.
When ignition switch 20 is in the drive position, a positive voltage will be supplied across fuse 13 and terminal +15 (159) to terminal 7 of the
pictogram.
If an open-circuit should occur in one of the two lighting circuits, e.g. for dipped beam filaments 12, the resulting unbalance will cause the relay to be
energized. The relay contacts will then close and terminal C2 will be earthed. The circuit for the left-hand lamp and the central warning lamp of the
pictogram will be earthed and the lamps will light up.
If an open-circuit should occur in the supply to both lamps in an external lighting circuit, no unbalance will occur and no fault indication will therefore
be provided.
If fuse 29 or 30 for the parking lights should blow, unbalance will occur in the filament monitor relay for the rear lights and fault indication will then
be provided on the pictogram. This is due to the fact that the filament monitor relay for the rear lights has a separate supply from fuse 29 or 30.
Oil pressure warning lamp
The oil pressure warning lamp is intended to warn the driver that the engine oil pressure is below the predetermined value.
When the ignition switch is in the drive position, a positive voltage will be supplied to oil pressure transmitter 44, across fuse 13 and terminal +15 in
the electrical distribution box, and across warning lamp 47D located in pictogram 213. If the lubricating oil pressure should drop below 0.3-0.5 bar,
the oil pressure transmitter will close the circuit and the lamp will light up.
At the same time as lamp 47D is earthed and lights up, the central warning lamp of the pictogram will be earthed, causing the pictogram to light up.
Cars for the European market (except SE, FI and GB)
Cars for the European market differ in that the filament monitor includes an additional circuit for supervising brake light switch 29. The supply for the
circuit is taken from terminal +15.
The system is performing correctly if the pictogram warning lamp for the rear lights lights up when the ignition is switched on, and is then switched off
when the brake pedal has been depressed.
Cars for the US and CA markets
Cars for these markets differ in that a special supervisory function is added for high-level brake light 109. If the car is braked (pin 54 live) and the
bulb in the high-level brake light does not light up, terminal C1 will be earthed. The pictogram will then indicate a fault in the rear lights.
Testing of Indicating and warning lamps
Certain bulbs in pictogram 213 can be checked by setting ignition switch 20 to a special test position. The test position is between the drive and start
positions of the ignition switch.
When the ignition switch is set to the drive position, the lamps to be tested will receive a positive supply across fuse 13 and terminal +15. (Terminal 7
on the pictogram).
When the ignition switch is then turned to the test position, the positive supply will remain and the lamps will be earthed simultaneously, since
terminals C and C1 in the ignition switch will be interconnected.
The following lamps in the pictogram will be connected during the test:
Central warning lamp
The lamps for the front lights
The lamps for the rear lights
Oil pressure warning lamp
Fault-tracing hints
The warning lamps in pictogram 213 can be activated by setting ignition switch 20 to the drive position.
1. Check fuse 13 and check that the supply to it is live.
2. Check that the supply to terminal 9 (1987)17 (1988) on the pictogram is live.
3. Check the relevant bulbs in the pictogram. Carry out this check with the ignition switch in the test position (terminals C and C1 interconnected).
4. Check that terminal 15 of the relay is energized in the drive position (only on cars for the EU market except SE, FI and GB).
5. Disconnect and earth the cable connected to the oil pressure transmitter. If the lamp lights up, the circuit is in good condition.
