8) Drive the vehicle at least 30 km/h (19 MPH) with
cruise speed set.
9) If the cruise speed is canceled itself (without do-
ing any cancel operations), DTC will appear on se-
lect monitor display.
CAUTION:
 DTC will also appear when cruise cancel is ef-
fected by driver. Do not confuse.
 Have a co-worker ride in the vehicle to assist
in diagnosis during driving.
NOTE:
DTC will be cleared by turning the ignition switch or
cruise control main switch to OFF.3. REAL-TIME DIAGNOSIS
1) Connect the select monitor.
2) Turn the ignition switch and cruise control main
switch to ON.
3) Turn the Subaru Select Monitor switch to ON.
