RH Rear Door

RH Rear Door

To superlock the RH rear door, the CCU (C0430) provides a feed to the RH rear door superlock motor (C0442) on an NK wire. The superlock motor (C0442) is provided an earth path via the CCU (C0430) on an O wire. This powers the superlock motor to the lock position, inhibiting the interior door handle.

To unlock the RH rear door from the superlock condition, the CCU (C0430) provides a feed to the RH rear door lock motor and the superlock motor (C0442) on an O wire. The RH rear door lock motor and the superlock motor (C0442) are provided an earth path via the CCU (C0430) on a K wire. This powers both motors to the unlock position.

Horns

If the anti-theft alarm is triggered, the CCU (C0430) provides an earth path for the horn relay coil (C0576) on a PY wire. The energised horn relay (C0570 & C0576) provides a feed to the LH (C0003) and RH (C0004) horns on PB wires. The horns are earthed on B wires.

By switching the earth path for the relay coil on and off, the CCU can control the operation of the horns.

Direction Indicator/Hazard Warning Lamps

If the anti-theft alarm is triggered, the CCU (C0593) provides an earth path for the hazard warning relay coil. The energised hazard warning relay provides a feed to the following:

The LH rear direction indicator lamp (C0121) on a GR wire The RH rear direction indicator lamp (C0125) on a GW wire The LH front direction indicator lamp (C0009) on a GR wire The RH front direction indicator lamp (C0011) on a GW wire The trailer pick-up (C0499) on a GR and GW wire.

All are earthed on B wires, except the trailer pick-up which is earthed on a W then B wire.

By switching the earth path for the relay coil on and off, the CCU can control operation of the direction indicator lamps. For more information, refer to the Direction Indicator/Hazard Warning Lamps section of this manual.  DIRECTION INDICATOR/HAZARD WARNING LAMPS.
