Hazard Warning Lamps

Hazard Warning Lamps

Feed from the positive battery terminal (C0192) is supplied to fusible link 4 and fuse 7 of the engine compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) provides a constant battery feed to the Central Control Unit (CCU) (C0593) and fuse 14 of the passenger compartment fuse box (C0587) on an NW wire. Fuse 14 (C0589) is connected to the hazard warning lamp housed within the instrument pack (C0230) by a P wire. Illumination of the hazard warning lamp (C0233) is controlled by the hazard warning switch (C0096) on an SY wire.

Fuse 7 of the engine compartment fuse box (C0576) provides a constant battery feed to the hazard warning switch (C0096) on an NO wire. When the hazard warning switch is pressed, current flows across the switch (C0096) to the flasher unit (C0580) on an LGK wire. The flasher unit (C0587) is earthed on a B wire. The energised flasher unit (C0580) returns a feed back to the hazard warning switch (C0096) on an LGN wire. The hazard warning switch (C0096) is now able to provide feeds to both the LH and RH direction indicator circuits simultaneously on GR and GW wires respectively.

Fuse 7 of the engine compartment fuse box (C0576) also provides a constant battery feed to the hazard warning relay (C0581) on an NO wire. The earth path for the hazard warning relay is controlled by the CCU (C0593). For more details on hazard warning relay and CCU operation, refer to the Electrics section of the System Description and Operation Workshop manual, and the Anti-theft Alarm and Central Door Locking (CDL) section of this manual.
