Inputs and Outputs Two connectors provide the interface between the PDC ECU and the external PDC components.
The ECU receives inputs from the following: l Reverse lamp circuit – for system activation when reverse gear is selected l PDC switch – for activation and de-activation of the system l Ignition switch – power supply for system operation.
The ECU outputs to the following: l Sensors – power and ground connections l Sensor – digital signal transmit and receive signals l Sounder – signal for sounder operation l PDC Switch – power supply for switch LED operation.
Diagnostics The PDC ECU has no diagnostic connection to enable faults to be retrieved using TestBook/T4. An on-board diagnostic routine monitors the system and alerts the driver to a system fault by emitting a tone from the sounder.
If a PDC system fault has occurred, the sounder will emit a continuous tone for 3 seconds and the PDC switch LED will flash continuously when reverse gear is selected.
