Central Door Locking (CDL) Power Distribution

Central Door Locking (CDL) Power Distribution

Feed from the positive battery terminal (C0192) is supplied to the following on an R wire:

Fusible link 1. Fuse 11. Fuse 15. Fuse 24. Fuse 60.

All are located in the passenger compartment fuse box (C0632). Fuse 15 (C0586) provides a constant battery feed to the BCU (C0660) on an RS wire. Fuse 60 (C0582) also provides a feed to the BCU (C0662) on an RW wire. The BCU (C0660) is earthed on an NB wire.

Fuse 24 (C0583) provides a constant battery feed to the passenger door module (C2016) on an RW wire. Fuse 11 (C0585) provides a constant battery feed to the drivers door module (C2017) on an RP wire.

Fusible link 1 (C0588) is connected to fuse 14 and fuse 16 of the rear fuse box (C2024) on an R wire. Fuse 14 (C2022) provides a constant battery feed to the RF receiver (C0674) on an RB wire. Fuse 16 provides a constant battery feed to relay 8, which is also located in the rear fuse box.

RF Receiver

The RF receiver (C0674) is located at the top of the upper tail door and is provided a constant battery feed from fuse 14 of the rear fuse box (C2022) on an RB wire. The RF receiver converts the radio frequency signals from the remote handset and converts them into a digital signals. The RF receiver (C0674) provides the digital signal to the BCU (C0660) on a WY wire. The BCU processes the signal from the RF receiver and carries out the appropriate function.

CDL Master Switch

The non-latching CDL master switch is mounted on the fascia, below the hazard warning switch. The BCU (C0661) monitors the condition of the switch (C0700) by providing a feed on an SN wire. When the switch is pressed, the switch contacts close and a momentary earth is created on an N wire. When the BCU registers this earth, it will lock all four doors, the tail door, and the fuel filler flap. Pressing the button a second time unlocks all four doors, the tail door and the fuel filler flap.

NOTE: Superlocking is not initiated when the CDL master switch is pressed.
