DESCRIPTION OF OPERATION
Certain parts of the car's lighting system are monitored by two filament monitors, 228a and 228b, and pictogram 213.

The five lamps f, g, d, e and j in the pictogram are covered individually in the Pictogram - Door Indication.

Filament Monitors
Filament monitor 228b monitors headlamp main and dipped beams and filament monitor 228a monitors rear lights and brake lights.

Filament monitor 228b incorporates relays which act on the pictogram and light lamp c if a failure occurs while filament monitor 228a incorporates shunt resistors which act on the pictogram and light lamp b if a failure occurs.

The lamp in the centre, a (central warning lamp), lights up the car's outline on the pictogram and always comes on when a failure is detected.

When ignition switch 20 is in the Drive position, current is supplied to pictogram terminal 5.

Front Filament Monitor 228b
If there is a fault in any lighting circuit, an imbalance arises and the relay is activated. Terminal C2 in the filament monitor and lamps C and A (central warning lamp) in the pictogram are grounded and the lamps light up.

Rear Filament Monitor 228a
The filament monitor senses if the current to one of the lamps is incorrect. Terminal C1 in the filament monitor and lamps b and a (central warning lamp) in the pictogram are grounded and the lamps light up.

The filament monitor incorporates a circuit for monitoring brake lights switch 29 and the high-level brake light, refer to Brake Lights.

Oil Pressure Warning Lamp 47d
The oil pressure warning lamp shows the driver if the engine oil pressure drops too low.

If the oil pressure drops below 0.3-0.5 bar, the oil pressure sensor closes and lamp 47d lights up.

The pictogram's central warning lamp is also grounded and the pictogram lights up.

Airbag Warning Lamp 47t
The airbag warning lamp shows the driver if there is a fault in the airbag system.

Testing The Indicator And Warning Lamps
When the ignition switch is turned to the Drive position, current is supplied to the lamps that are to be tested (terminal 5 on the pictogram).

When the ignition switch is then turned to the Test position, which is situated between the Drive and Start positions, positive current continues to be supplied to the lamps at the same time as they are grounded in that connections C and C1 of the ignition switch are connected to each other.

The following lamps in the pictogram are connected in circuit during the test:
^ Central warning lamp a
^ Lamp c for front lighting
^ Lamp b for rear lighting
^ Oil pressure warning lamp h/47d

FAULT DIAGNOSIS HINTS
The indicator lamps in pictogram 213 are activated by turning ignition switch 20 to the Drive position.
1. Check that current is supplied to terminal 5 of the pictogram.
2. Check the pictogram bulbs. Do this with the ignition switch in the Test position.
3. Check that terminal 1 of filament monitor 228a is supplied with current in the Drive position.
4. With the ignition switch in the Drive position, disconnect and ground the oil pressure sensor cable. If the lamp lights up, the circuit is OK.
5. Check the connectors, wiring harness and ground connections.

When changing the filament monitor, check against the spare parts catalogue that it is replaced with the correct variant for the market in question.
