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 a PDC switch, and a sounder.
For detailed information on PDC, refer to the .
Ignition Switch Circuit Supply
When the ignition switch is in position I, current flows from the ignition switch on an LGW wire to fuse 26 of the passenger compartment fusebox. Fuse 26 provides a feed to the auxiliary circuits relay coil on an LG wire. The relay coil is earthed on a B wire via earth header C0018.
When the ignition switch is in position II, current flows from the ignition switch on a Y wire to fuse 25 of the passenger compartment fusebox. Fuse 25 provides a feed to the reverse lamp switch (manual vehicles only) or the automatic transmission starter inhibitor/reverse lamp switch (automatic vehicles only) on a GY wire.
PDC ECU Circuit Supply
When energized, the auxiliary circuits relay provides a feed to fuse 16 of the passenger compartment fuse box on a WG wire. Current flows through fuse 16 to the PDC ECU on an LGO wire. The PDC ECU is earthed on a B wire vie earth header C0707.
