CRUISE CONTROL SYSTEM (DIAGNOSTICS)
5. Subaru Select Monitor
A: OPERATION
1. GENERAL DESCRIPTION
The on-board diagnosis function of the cruise con-
trol system uses Subaru Select Monitor.
The on-board diagnosis function operates in 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 driv-
ing although cruise cancel condition is not en-
tered.
(2) Cruise control memory in ECM stores the
cancel condition (Code No.) which occurred
during driving. When there are multiple cancel
conditions (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 signal emitted from switches, sen-
sors, etc.
(1) Vehicle cannot be driven at cruise speed
when the problem occurs in the cruise control
system or relevant circuits.
(2) Monitor the signal conditions from switches
and sensors.
2. CRUISE CONTROL CANCEL CONDI-
TIONS DIAGNOSIS
1) Prepare the Subaru Select Monitor kit.
2) Connect the diagnosis cable to Subaru Select
Monitor.
3) Insert the cartridge to 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», select the {2. Each Sys-
tem Check} and press the [YES] key.
On the system selection display screen, select the
{Engine} and press the [YES] key. Press the [YES]
key after the information of engine type is dis-
played.
8) Drive vehicle at least 40 km/h (25 MPH) and set
the cruise control.
9) When the cruise speed is canceled by itself
(without any cancel operations), DTC will be dis-
played on the screen after selecting the {Check
Cancel Code} and pressing the [YES] key on the
engine malfunction diagnosis screen.
CAUTION:
•When performing diagnosis, observe the le-
gal speed limit on the road.
•DTC will be also displayed when cruise con-
trol is cancelled by driver. Do not confuse them.
•Get an assistant in the vehicle for help of di-
agnosis while driving.
NOTE:
DTC will be cleared by turning ignition switch or
cruise control main switch to OFF.
3. REAL-TIME DIAGNOSIS
1) Connect the Subaru Select Monitor.
2) Turn the ignition switch and cruise control main
switch to ON.
3) Turn the Subaru Select Monitor switch to ON.
4) On the «Main Menu», select the {2. Each Sys-
tem Check} and press the [YES] key.
5) On the «System Selection» display screen, se-
lect the {Engine} and press the [YES] key.
6) Press the [YES] key after the information of en-
gine type is displayed.
7) On the «Cruise Control Diagnosis» display
screen, select the {Current Data Display/Save},
and then press the [YES] key.
8) Make sure that normal display is shown when
operated as follows:
•Depress and release the brake pedal. (Stop light
switch and brake switch turn ON.)
•Turn the main switch to ON.
•Turn the «CANCEL» switch to ON.
•Turn the «SET/COAST» switch to ON.
•Turn the «RESUME/ACCEL» switch to ON.
•Depress or release the clutch pedal.

when select lever is shifted into
“P” or “N” range? Is Subaru
Select Monitor OFF when
select lever is shifted to a
range other than the “P” or “N”
range?
Replace the ECM.
