USING A SUBARU SELECT MONITOR
With this testing procedure the defective component can be determined by directly monitoring input/output signals
of the ECM or the trouble codes.
Features
A variety of data can be checked without movements from
the drivers seat, passenger’s seat or from outside the vehicle.
This unit allows the identification of the type of malfunction,
for example whether the cause is an open or shorted wire in
the input/output signal line, or whether the breakdown of a
component is caused by a lack of maintenance.
Diagnosis
Refer to the reference values for input/output and control
data to determine whether the malfunction is caused by a worn
out component, an open wire, a short etc.
Perform the diagnostics procedure as described in chapter
“Check based on trouble codes”by monitoring the trouble
codes.
NOTE:
It will be easier to determine a malfunction if the vehicle data
for normal conditions are available for comparison.
