Diagnostics Theory

Interpreting Results

When a failure occurs, a message is displayed showing the number of failures and the

probability that the failure is caused by the assembly being tested. If the probability is not

high, more measurements may be necessary to verify the failure.

The probability assigned is based on the following criteria:

Low: A failure occurred, but the signal being used for the measurement originates in

another assembly and has not been previously tested on this assembly. Low probability is

also assigned for the ﬁrst measurement made to an assembly.

Medium: A failure occurred and the signal being used for the measurement originates in

another assembly and has already been measured good, but the measurement mux

(multiplex) point or digital detector has not previously been used.

High: A failure occurred and the signal being used for the measurement originated in

another assembly and has already been measured good, and the measurement mux point

or digital detector has already been used.

The RF diagnostics assign probability based on the ﬁrst failure that occurs. The audio

diagnostics assign probability based on a series of measurements.
