User Self Test ^ -
The self-test function built into the PDU software enables
users to completely test the system for faulty rnodules and,
cables. By following the screen instructions, faulty system
components can be identified.
Procedure
Select User Self-Test from the PDU main menu. The self-
test software will load from the C D .
The first screen shows the cable setup with the PDU
connected to the base station. After confirming that the
connections are correct, the self-test sequence begins.
The initial test is of the PDU and base station electronics
and takes slightly less than 2 minutes.
The user is then directed to connect the various external
elements of the system in turn and confirm the cable setup
at each stage. As each element is connected and tested,
the sequence will either direct that the next element is
connected or will report a fault in the last element tested.
Using this procedure, any faulty element in the system will
be identified. If the self-test concludes with no fault
reported, any problem encountered must be in the vehicle
or as a result of incorrect use.
