1. Basic Diagnostic Procedure
A: PROCEDURE
Step Check Yes No
1CHECK SECURITY INDICATOR LIGHT.
1) Turn the ignition switch to “OFF” or “ACC”.
2) Wait for 60 seconds or more.
Does the security indicator
light blink?
Go to step 2.Check the secu-
rity indicator light
circuit. (diag)-10, CHECK

2CHECK KEY SWITCH.
Remove the key from ignition switch.
Does the security indicator
light blink within 1 second after
removing the key?
Go to step 3.Check the key
switch circuit.

Does the security indicator
light go off?
Go to step 5.Go to step 4.
4CHECK ENGINE START.
Tu r n t h e i g n i t i o n s w i t c h t o S TA R T.
Does the starter operate? Check the LAN
communication cir-
cuit. LAN(diag)-2, Basic
Diagnostic Proce-
dure.>
Check the DTC
display (body inte-
grated unit). Go to
step 7.
5CHECK ENGINE START.
Tu r n t h e i g n i t i o n s w i t c h t o S TA R T.
Does the starter operate? Go to step 6.Check the LAN
communication cir-
cuit. LAN(diag)-2, Basic

dure.>
6CHECK ENGINE START.
Tu r n t h e i g n i t i o n s w i t c h t o S TA R T.
Does the engine start? Immobilizer sys-
tem is OK.
Check the DTC
display (ECM). Go
to step 7.
7CHECK ANY OTHER DTC ON DISPLAY.
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor to data
link connector. Select Monitor.>
3) Turn the ignition switch and Subaru Select
Monitor switch to ON.
4) Read DTC on display.
Is the DTC displayed on
screen?
Go to step 8.Repair the related
parts.
8PERFORM THE DIAGNOSIS.
1) Inspect using the “Diagnostic Procedure
with Diagnostic Trouble Code (DTC).” IM (diag)-16, Diagnostic Procedure with Diag-
nostic Trouble Code (DTC).>
2) Repair the trouble cause.
3) Perform the clear memory mode.
4) Read DTC again.
Is the DTC displayed on
screen?
Inspect using the
“Diagnostic Proce-
dure with Diagnos-
tic Trouble Code
(DTC).” (diag)-16, Diag-
nostic Procedure

Finish the diagno-
sis.

2. BODY INTEGRATED UNIT
NOTE:
In immobilizer system, performing the starter relay control. When the body integrated unit detect the incon-
formity of reference code, immediately out put the starter relay cut signal to ECM, and then ECM stop the
starter relay operation. In this case, engine does not start, and DTC is not recorded in ECM. Check that the
engine does not start on the DTC of body integrated unit.
