Tire Pressure Warning Light/Trouble Indicator Light Illumination Pattern (DTC)
TIRE PRESSURE MONITORING SYSTEM (DIAGNOSTICS)
1) When the tire pressure warning light does not illuminate in accordance with this illumination pattern, there
must be an electrical malfunction.
2) When tire pressure warning light does not go off, check the tire pressure monitoring control module/warn-
ing light circuit and the combination meter circuit.
(DTC).>
NOTE:
If the problem is fixed while driving at approximately 40 km/h (25 MPH) after the tire pressure warning light
blinks/lights, the warning light goes out and the tire pressure monitor system operates normally. (If there is
a decrease in tire pressure, or malfunction of the system, the past malfunctions are displayed.)
B: TIRE PRESSURE WARNING LIGHT DOES NOT ILLUMINATE
DETECTING CONDITION:
•Defective combination meter
•Defective harness
TROUBLE SYMPTOM:
When the ignition switch is turned to ON (engine OFF), the tire pressure warning light does not come on (for
approximately 2 seconds).

1. Basic Diagnostic Procedure
A: PROCEDURE
NOTE:
•To check the harness for broken wires or short circuits, shake problem spot or connector.
•Refer to “Check List for Interview”.
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Ask the customer when and how the trou-
ble occurred using the interview checklist.
2) Before performing diagnostics, check the
component which might affect VDC problems.
Is the component that might
influence the VDC problem
normal?
Go to step 2.Repair or replace
each component.
2CHECK INDICATION OF DTC.
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor to data
link connector.
3) Turn the ignition switch to ON, and the Sub-
aru Select Monitor power switch to ON.
4) Read the DTC.
(DTC).>
NOTE:If the communication function of the Subaru Se-
lect Monitor cannot be executed normally,
check the communication circuit.
TIALIZING IMPOSSIBLE, INSPECTION, Sub-
aru Select Monitor.>
5) Record all DTCs and freeze frame data.
Is DTC displayed? Go to step 4.Go to step 3.

3. General Description
A: CAUTION
1. SRS AIRBAG SYSTEM
Airbag system wiring harness is routed near the
ABS wheel speed sensor and VDCCM&H/U.
CAUTION:
•All airbag system wiring harness and con-
nectors are colored yellow. Do not use the elec-
trical test equipment on these circuits.
•Be careful not to damage the airbag system
wiring harness when servicing the ABS wheel
speed sensor and VDCCM&H/U.
B: INSPECTION
Before performing diagnosis, check the following
items which might affect VDC problems.
1. BATTERY
Measure the battery voltage and check electrolyte.
Standard voltage: 12 V or more
Specific gravity: 1.260 or more
2. GROUND
Check the tightening torque of ground (GB-7) bolt
of VDC.
Tightening torque:
13 N·m (1.3 kgf-m, 9.6 ft-lb)
3. BRAKE FLUID
1) Check the brake fluid level.
2) Check the brake fluid for leaks.
4. HYDRAULIC UNIT
Check the hydraulic unit.
•With brake tester
