Basic Diagnostic Procedure
LAN SYSTEM (DIAGNOSTICS)
1. Basic Diagnostic Procedure
A: PROCEDURE
1. WITH SUBARU SELECT MONITOR
CAUTION:
•Subaru Select Monitor is required for reading DTC, performing diagnosis and reading current data.
•Remove foreign matter (dust, water, oil, etc.) from the body integrated unit connector during re-
moval and installation.
•For model with immobilizer, registration of immobilizer may be needed after the replacement of
controller etc. For detailed procedure, refer to the REGISTRATION MANUAL FOR IMMOBILIZER.
NOTE:
•To check harness for broken wires or short circuits, shake trouble spot or connector.
•Check List for Interview.
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Ask the customer when and how the trou-
ble occurred using interview check list.
2) Check the display of communication error
display. (Combination meter, odo/trip meter)
Is the communication error dis-
played?
Go to step 3.Go to step 2.
2BASIC INSPECTION
Check the components which might affect
body control.
Is the component that might
influence the body control
problem normal?
Go to step 3.Repair or replace
each component.
3CHECK INDICATION OF DTC.
1) Read DTC of all systems.
CODE (DTC), OPERATION, Subaru Select
Monitor.>
NOTE:•The LAN system is for the overall vehicle, so
read the DTC of all systems.
•If the communication function of the Subaru
Select Monitor cannot be executed normally,
check the communication circuit.

2) Record all DTC.
Is a DTC other than CAN com-
munication displayed in the
output code?
