5. Subaru Select Monitor
A: OPERATION
1. GENERAL
S003503A1604
The on-board diagnosis function of the cruise con-
trol system uses an external Subaru Select Moni-
tor.
The on-board diagnosis function operates in two
categories, which are used depending on the type
of problems;
1) Cruise cancel conditions diagnosis
(1) This category of diagnosis requires actual
vehicle driving in order to determine the cause,
(as when cruise speed is cancelled during driv-
ing although cruise cancel condition is not
entered).
(2) Cruise control module memory stores the
cancel condition (Code No.) which occurred
during driving. When there are plural cancel
conditions (Code No.), they are shown on the
Subaru Select Monitor.
CAUTION:
¼ The cruise control memory stores not only
the cruise "cancel" which occurred (although
"cancel" operation is not entered by the
driver), but also the "cancel" condition input by
the driver.
¼ The content of memory is cleared when igni-
tion switch or cruise main switch is turned OFF.
2) Real-time diagnosis
The real-time diagnosis function is used to deter-
mine whether or not the input signal system is in
good order, according to signal emitted from
switches, sensors, etc.
(1) Vehicle cannot be driven at cruise speed
because problem occurs in the cruise control
system or its associated circuits.
(2) Monitor the signal conditions from switches
and sensors.
