PDC ECU

PDC ECU







The PDC ECU is located in the LH side of the luggage compartment. A bracket is attached to the 'E' post, behind the trim panel and provides for the attachment of the ECU and the PDC sounder.

On vehicles without rear air conditioning, the bracket is located inboard on the LH 'E' post, adjacent to the luggage compartment trim panel. On vehicles with rear air conditioning, the bracket is located outboard on the LH 'E' post, adjacent to the outer body panel.

The bracket has integral studs which provide for the attachment of the ECU with nuts. The ECU is located with the harness connectors uppermost to assist access. The PDC sounder is located on the opposite side of the bracket and is secured with screws, lockwashers and nuts.

Inputs and Outputs
Two connectors provide the interface between the PDC ECU and the external PDC components.

The ECU receives inputs from the following:
^ Reverse lamp circuit - for system activation when reverse gear is selected.
^ PDC switch - for activation and de-activation of the system
^ Ignition switch - power supply for system operation.

The ECU outputs to the following:
^ Sensors - power and ground connections.
^ Sensor - digital signal transmit and receive signals.
^ Sounder - signal for sounder operation.
^ 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.
