DESCRIPTION OF OPERATION
Direction indicators
Current is supplied via fuse 33 to the direction indicator stalk switch and then to pins 18 (left) and 19 (right) of ICE control module 500.

The ICE control module sends current pulses to the left-hand and right-hand direction indicator lamps.

In positions L1 and R2 of the direction indicator stalk switch, the left-hand and right-hand direction indicator lamps will flash as long as the stalk switch is held in the corresponding position.

In positions L and R, activation of the direction indicators takes place in the same manner except that the stalk switch returns automatically to the neutral position when the steering wheel is returned to the straight-ahead position.

The two indicator lamps 47H (left) and 47I (right) are connected in parallel with the direction indicator lamps.

Direction indicator lamps on a trailer, if any, are supplied with current via connector 258 (H8-5).

Hazard flashers
Current is supplied to pin 24 of the ICE control module via fuse 2.

When the hazard flashers switch is actuated, the contacts close and pin 21 of the ICE control module is connected to ground.

The ICE control module supplies current pulses to the left-hand and right-hand direction indicator lamps, to the two indicator lamps 47H and 47I in the main instrument display panel and to side direction indicators 89 and 90, which all start to flash.

When the switch is actuated, the indicator lamp in the switch button will also light up.

Direction indicator lamps on a trailer, if any, are sup- plied with current via connector 258 (H8-5).

FAULT DIAGNOSIS HINTS
Direction indicators
The car's direction indicators are operative only when the ignition switch is in the Drive position.
1 Check that fuse 33 is intact and supplied with current.
2 Check that current is present on pin 3 of the direction indicator stalk switch.
3 Check that the bulbs are OK and supplied with current.
4 Check the connectors, wiring harness and ground connections.

Hazard flashers
The car's hazard flashers are always supplied with current via pin 21 of the ICE control module.
1. Check that fuse 2 is intact and supplied with current.
2. Check that current is present on pin 24 of the ICE control module.
3. Check that the bulbs are OK and supplied with current.
4. Check connectors, wiring and ground connections.
