OPERATION

General

Feed from the positive battery terminal (C0192) is supplied to fusible link 3 of the engine compartment fuse box (C0632) on an R wire. Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C0028) to fuse 2 of the passenger compartment fuse box (C0588) on an NW wire.

Fuse 2 (C0580) provides an ignition feed to the following on G wires:

The reverse lamp relay (C0935) (automatic transmission vehicles only). The brake pedal switch (C0075).

Fuse 2 (C0581) also provides an ignition feed to the reverse lamp switch (C0163) (K1.8 and Td4 manual transmission vehicles only) on a G wire.

Brake Lamps

The brake pedal switch (C0075) is provided an ignition feed from fuse 2 of the passenger compartment fuse box (C0580) on a G wire. When the brake pedal is pressed, current flows across the switch (C0075) to the following on GP wires:

The RH brake lamp (C0125). The RH brake lamp (C0489) (NAS vehicles only). The LH brake lamp (C0121). The LH brake lamp (C0490) (NAS vehicles only). The Centre High Mounted Stop Lamp (CHMSL) (C0613). The trailer pick-up (C0499) (GP then R wire). The ABS ECU (C0500) (01MY vehicles). The ABS ECU (C0501) (02MY vehicles).

All brake lamps are earthed on a B wire. The trailer pick-up is earthed on a W then B wire

NOTE: The brake pedal switch (C0075) provides a second feed to the ABS ECU on a GR wire. For more information on ABS operation, refer to the 'Anti-lock Braking System (ABS) – 01MY' or 'Anti-lock Braking System (ABS) – 02MY' section of this manual.

 ANTI-LOCK BRAKING SYSTEM (ABS) – 01MY.  ANTI-LOCK BRAKING SYSTEM (ABS) – 02MY.

Reverse Lamps Manual Transmission

Fuse 2 of the passenger compartment fuse box (C0581) provides an ignition feed to the reverse lamp switch (C0163) on a G wire. When reverse gear is selected, current flows across the switch (C0166 on K1.8 vehicles, C0163 on Td4 vehicles) to the RH (C0455) and LH (C0472) reverse lamps on GN wires. Both lamps are earthed on B wires.
