CRUISE CONTROL SYSTEM (DIAGNOSTIC)
Subaru Select Monitor
5. Subaru Select Monitor
A: OPERATION
1. GENERAL
The on-board diagnosis function of the cruise con-
trol system uses the Subaru Select Monitor.
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 ve-
hicle driving in order to determine the cause, (as
when cruise speed is cancelled during driving al-
though cruise cancel condition is not entered).
(2) Cruise control memory of 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 “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
1) Prepare the Subaru Select Monitor kit.
2) Connect the diagnosis cable to Subaru Select
Monitor.3) Insert the cartridge into Subaru Select Monitor.
4) Connect the Subaru Select Monitor to data link
connector.
(1) Data link connector is located in the lower
portion of the instrument panel (on the driver’s
side).
(2) Connect the diagnosis cable to data link
connector.
5) Start the engine and turn the cruise control main
switch to ON.
6) Turn the Subaru Select Monitor switch to ON.
7) On the «Main Menu» display screen, select the
{2. Each System Diagnosis} and press [YES] key.
Select the {Engine} on the System Selection dis-
play screen and press [YES] key. Press [YES] key
after the engine type displayed.
8) Drive the vehicle at least 40 km/h (25 MPH) with
cruise speed set.
