DESCRIPTION OF OPERATION
US And CA Markets
In the US and CA markets, dipped headlamps are used as daylight driving lights. The lamps go on when the ignition switch is turned to the Drive position. The car's parking lights, rear lights, number plate lighting and side marker lights also go on.

When ignition switch 20 is in the Drive position and lights switch 10 in position 0 or 1, current is supplied from terminal 87A of relay 174 to dipped beam filaments 12 via filament monitor 228b and fuses 5 and 6.

When the lights switch is in position 2, relay 174 obtains operating current from terminal 56 ot the lights switch. The relay operates and the daylight driving lights are disconnected to avoid reverse currents.

Filament Monitor 228b
If any of the main beam or dipped beam filaments fails, the dipped beam relay in the filament monitor operates and terminal C2 is grounded. Since positive current is applied to terminal 9 of pictogram 213 (from the ignition switch), the lighting indicator lamps and the central warning lamp light up. See also the Pictogram-Filament monitor.

FAULT DIAGNOSIS HINTS
The daylight driving lights are activated when ignition switch 20 is in the Drive position and lights switch 10 is in position 0 or 1 (US/CA) or only in position 0 (other markets).
1. Check that fuses 5 and 6 (dipped beam) are intact and supplied with current.
2. Check that the bulbs are intact and supplied with current. Check the grounding.
3. Check the lights switch, relay 174 (US/CA) and the filament monitor connections.
4. Check the connectors, wiring harness and ground connections.

IMPORTANT: When changing the bulbs, make sure that the new bulbs are of the correct rating. Otherwise, the lamps in the pictogram may light up due to imbalance in the filament monitor coil.
