General
Park Distance Control (PDC) provides an audible warning to the driver when any obstacles are in the path of the vehicle during forward and reverse parking maneuvers. The system consists of four ultrasonic sensors in each bumper, an ECU, a sounder and a parking switch.
For detailed information on PDC, refer to DRIVING AIDS .
Power Distribution
Feed from the positive battery terminal (C0192) is supplied to fuse 27 and fuse 53 of the passenger compartment fuse box (C0632) on an R wire. Fuse 27 (C0582) provides a constant battery feed to the Body Control Unit (BCU) (C0662) on an RP wire.
Fuse 53 (C0583) provides a constant battery feed to the ignition switch (C0099 on Td6 vehicles, C0028 on V8 vehicles) on an R wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C0099 on Td6 vehicles, C0028 on V8 vehicles) to fuse 6 of the passenger compartment fuse box (C0585) on a G wire. Fuse 6 (C0587) provides an ignition feed to the PDC ECU (C0957) on a GN wire. The PDC ECU (C0957) is earthed on an NB wire.
PDC Switch
The PDC ECU (C0957) monitors the condition of the PDC switch (C0700) by providing a feed on an NUY wire. When the switch is pressed, an earth path is created on an N wire. Sensing this, the PDC initiates the PDC system, and provides a feed to the switch tell-tale LED (C0700) on an NWY wire.
RH Outer Sensor
The PDC ECU (C0958) provides a feed to the RH outer PDC sensor (C0966) on a GP wire. An earth path is provided for the sensor by the PDC ECU on an NY wire. The PDC sensor outputs a pulsed signal to the PDC ECU on a YN wire, which the PDC ECU translates into a distance reading.
