DESCRIPTION OF OPERATION
Certain parts of the car's lighting system are monitored by two filament monitors 228A and B and pictogram 213.
The five lamps F, G, D, E and J in the pictogram are covered individually in, the Pictogram-Door Indication.
Filament Monitor
Filament monitor 228B monitors full 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 there is a fault while filament monitor 228A incorporates shunt resistors which act on the pictogram and light lamp B if there is a fault.
The lamp in the centre, A (central warning lamp), lights up the car's outline on the pictogram and always comes on when a fault is detected.
When ignition switch 20 is in the Drive position, current is supplied to pictogram terminal 5.
Front Filament Monitor
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
The filament monitor senses if the current to one of the lamps is incorrect. Terminal Olin the filament monitor and lamps B and A (central warning lamp) in the pictogram are grounded and the lamps light up.
In certain markets, the filament monitor incorporates a circuit for monitoring brake light switch 29. See Brakes Lights With/Without Reset Memory.
For high-level brake lights, there is a special monitoring function for brake light 109, see Brake Lights and High-level Brake Light.
Oil Pressure Warning Lamp 47D
The oil pressure warning lamp shows the driver if the engine oil pressure becomes too low.
If the engine oil pressure drops below 0.3-0.5 bar, the engine oil pressure sensor closes and lamp 47D lights up.
The pictogram 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, see Airbag.
Testing The Indicator And Warning Lamps
When the ignition switch is turned to the Drive position, current is supplied to those 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 at the same time as the lamps are grounded as connections C and C1 of the ignition switch are connected to each other.
The following lamps in the pictogram are connected in circuit during testing:
^ 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, see above.
3. Check that terminal 1 of filament monitor 228A is supplied with current in the Drive position (certain markets only).
4. With the ignition in the Drive position, disconnect and ground the engine 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.
