CRUISE CONTROL SYSTEM (DIAGNOSTICS)
5. Subaru Select Monitor
A: OPERATION
1. GENERAL DESCRIPTION
For the on-board diagnosis function of the cruise
control system, use Subaru Select Monitor.
The on-board diagnosis function operates under
two categories, which are used depending on the
type of problems;
1) Cruise Control 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 driving
although cruise cancel condition is not entered.
(2) Cruise control memory in ECM stores the
cancel condition (Code No.) which occurred dur-
ing driving. When there are plural cancel condi-
tions (Code No.), they are shown on the Subaru
Select Monitor.
CAUTION:
• 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.
• The content of memory is cleared when igni-
tion switch or cruise control main switch is
turned OFF.
2) Real-time Diagnosis
Real-time diagnosis function is used to determine
whether or not the input signal system is in good or-
der, according to the signal emitted from switches,
sensors, etc.
(1) Vehicle cannot be driven at cruise speed
when problem occurs in the cruise control sys-
tem or its associated circuits.
(2) Monitor the signal conditions from switches
and sensors.
