Control Components

Control Components
The complexity of the electronics involved with the various electronic control modules and the two multiplexed communication networks, preclude the use of workshop general electrical test equipment Therefore, reference should be made to the PDU User Guide for detailed instruments on testing the DATC control unit.

The PDU systematically tests and analyses all functions of the DATC control unit and the electrically controlled heating system.

Where a fault involving the DATC control unit and electrically controlled heating system is indicated by the PDU, some basic diagnostic methods may be necessary to confirm that connections are good that wiring is not damaged, before installing new components.
