Warning Light Illumination Pattern
VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)
10.Warning Light Illumination Pattern
A: INSPECTION
1) When warning lights or indicator lights do not illuminate in accordance with this illumination pattern, there
must be an electrical malfunction.
2) When warning lights or indicator lights remain constantly OFF, check the combination meter circuit or CAN
communication circuit.
3) When ABS warning light does not go off, check the combination meter circuit.
(1) Ignition switch (8) 1.5 seconds (12) Brake warning light (EBD warning
light)(2) OFF (9) VDC indicator light
(3) ON (10) VDC warning light and TCS OFF
indicator light
(13) Parking brake
(4) Engine start (14) Released
(5) ABS warning light (11) Several seconds (depending on
engine coolant temperature)(6) Light OFF

4) When the VDC indicator light, VDC warning light and TCS OFF indicator light do not go off, check the com-
bination meter circuit or CAN communication circuit.
NOTE:
•Even though the ABS warning light does not go off after 1.5 seconds from ABS warning light illumination,
the ABS system operates normally when the warning light goes off while driving at approximately 12 km/h (7
MPH). However, the ABS system does not work while the ABS warning light is illuminated.
•It may take several minutes before VDC warning light and TCS OFF indicator light goes off if the vehicle
is parked under low temperature for a specified time. This is not defective because it is resulted from low en-
gine coolant temperature.
•With the vehicle jack-up/lift-up or set on free rollers, when the wheels lock or spin after starting the engine,
ABS warning light, VDC warning light and TCS OFF indicator light may illuminate because VDCCM&H/U de-
tects the abnormal conditions from ABS wheel speed sensors. In this case, this is not a malfunction. Perform
the clear memory mode.
B: VDC WARNING LIGHT, TCS OFF INDICATOR LIGHT AND VDC INDICATOR
LIGHT DO NOT COME ON
DETECTING CONDITION:
•Defective combination meter
•Defective CAN communication
TROUBLE SYMPTOM:
When the ignition switch is turned to ON (engine OFF), VDC indicator light, VDC warning light and TCS OFF
indicator light do not come on.
NOTE:
When pressing the TCS OFF switch for more than 10 seconds, the TCS OFF indicator light goes off and can-
not operate any more. When turning the ignition switch from OFF to ON, the OFF operation enabled status
is restored.
Step Check Yes No
1CHECK OTHER INDICATOR LIGHT.
Tu r n t h e i g n i t i o n s w i t c h t o O N .
Does other indicator light illu-
minate soon after “ON”.
Go to step 2.Perform the self-
diagnosis of com-
bination meter.
2CHECK VDCCM.
When the engine does not start, display the
current data of VDCCM using Subaru Select
Monitor.
Is “VDC warning light” output
set to “ON”?
Go to step 3.Replace the
VDCCM&H/U.
3CHECK LAN SYSTEM.
Perfor m the diagnosis for LAN system.
Tr o u b l e C o d e ( D T C ) . >
Is there any fault in LAN sys-
tem?
Pe r for m t h e d ia g -
nosis according to
DTC for LAN sys-
tem.
Go to step 4.
4CHECK COMBINATION METER.
Check the combination meter.
Is combination meter OK? Replace the
VDCCM&H/U.
Repair the combi-
nation meter
assembly.
