General
Park Distance Control (PDC) provides an audible warning to the driver when any obstacles are in the path of the vehicle during reverse parking maneuvers. The system consists of
- Four ultrasonic sensors mounted in the rear bumper.
- An ECU mounted on the RH side of the luggage compartment.
- A sounder mounted on the RH side of the luggage compartment.
- A non-latching master switch mounted in the rear of the center console.
The non-latching master switch also contains a tell-tale LED to inform the driver the system is operational. When the system is activated, a confirmation tone is emitted as further confirmation the system is operational. The system is only operational when reverse gear is selected and the master switch is pressed (LED illuminated).
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 provides an ignition feed to the reverse lamp switch (C0163) on a G wire (manual transmission vehicles only) or the reverse lamp relay (automatic transmission vehicles only), which is located within the passenger compartment fuse box.
When in the 'ignition' position, the ignition switch (C0028) also provides a feed to fuse 24 of the passenger compartment fuse box (C0588) on a G wire. Fuse 24 (C2624) provides an ignition feed to the PDC ECU (C0958) on an LGO wire.
PDC ECU
The PDC ECU will only initiate PDC if reverse gear is selected and the PDC switch is pressed. The PDC ECU monitors driver requests as follows
PDC Switch
The PDC ECU (C0958) monitors the condition of the non-latching PDC switch (C0404) by providing a feed on a BS wire. When the switch is pressed, a momentary earth is created on a B wire.
