DTC table
A fault may be either intermittent or permanent. An
intermittent fault is defined as a fault which is
temporary and, in certain cases, recurrent. A
permanent fault is one which is present continuously.
In the case of all diagnostic system faults with the
exception of a faulty KS signal or ICM knock control
circuit, the control module will re–adopt the correct
value of a previously faulty or missing signal once
the signal has been restored, rather than continuing to
use a fixed substitute value. In the case of output
signals, however, the engine must have been stopped.
The DTC remains stored in the control module for a
specific duration.
