DESCRIPTION AND OPERATION
PDC Switch
The PDC switch is located in the rear of the centre console. The switch has a momentary, non-latching action, which
switches a positive output from the PDC ECU to ground when pressed. This signal is used by the ECU to switch the
PDC between the activated and de-activated conditions. The switch is connected to the PDC ECU via a harness
connector which is integrated into the vehicle body harness.
The switch contains an LED. When the system is active (i.e. an obstacle is detected) the LED illuminates to show the
active condition.
When the PDC is switched from the off condition to the active condition, the LED is illuminated, along with a chime
from the sounder, to signal that the system has been activated.
If a fault exists in the PDC system, the ECU flashes the LED continuously, when the switch is pressed to activate the
system.
