Direction Indicators And Hazard Warning Lamps Description
The direction indicator lamps are operated from a three position direction indicator switch located on the left hand side of the steering column and only operate with the ignition switch in position II. Left and right indicator lights in the instrument pack flash accordingly to show correct flasher operation. If a failure of an indicator bulb occurs, the appropriate flasher symbol on the instrument pack will flash quickly.
The hazard warning lamps are operated from a latching pushbutton switch located in the group of six switches on the fascia. When the switch is pushed both left and right indicator lights in the instrument pack flash to show hazard warning lamps are operating and all hazard warning lamps flash simultaneously. The hazard warning flashers operate independently of the ignition switch position.
If a trailer is fitted and connected to the trailer pick-up socket, a trailer symbol in the instrument pack also flashes to show correct operation of the trailer direction indicator/hazard warning lamps.
Two direction indicator/hazard warning lamps are located outboard of the head lamps. Two side repeater lamps are located on the left and right hand front wings, forward of the A posts. Two rear direction indicator/hazard warning lamps are located in the rear bumper All direction indicator/hazard warning lamp bulbs are rated at 5 Watts.
The direction indicators and hazard warning lamp operation is controlled by the Body Control Unit (BCU), Intelligent Driver Module (IDM) and two electronic relays in the passenger compartment fusebox. The IDM and the relays are are an integral part of the passenger compartment fusebox and cannot be serviced individually.
The direction indicator circuit uses the serial data bus between the BCU IDM and the instrument pack for flasher and hazard request and operation.
Direction Indicators and Hazard Warning Lamps Supply
Circuit Supply
A feed from the battery positive terminal is connected by an R wire to the engine compartment fusebox where it passes through fusible link 8 and fuse 14.
A feed from fuse 14 is connected to the passenger compartment fusebox on a PN wire where it is connected to the contacts and coils of the RH and LH indicator relays in the fusebox.
A feed from fusible link 8 is connected on an NW wire to the passenger compartment fusebox and from the fusebox to the ignition switch on an N wire.
Ignition switch supply
With the ignition switch in position II, the feed from fusible link 8 flows through the ignition switch to the passenger compartment fuse box on a Y wire. The feed continues through fuse 29 in the passenger compartment fusebox and is connected on a GU wire to the BCU pin C0660-1.
