CRUISE CONTROL SYSTEM (DIAGNOSTIC)
Subaru Select Monitor
5. Subaru Select Monitor
A: OPERATION
1. GENERAL
The on-board diagnosis function of the cruise control
system uses an external Subaru Select Monitor.
The on-board diagnosis function operates in two cat-
egories, 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 en-
tered).
(2) Cruise control module memory 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 “can-
cel” 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 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 be-
cause problem occurs in the cruise control sys-
tem or its associated circuits.
(2) Monitor the signal conditions from switches
and sensors.
2. CRUISE CANCEL CONDITIONS DIAG-
NOSIS

side).

nector.
