Diagnosis of DTCs C1249

INTRODUCTION
This bulletin provides a diagnostic and adjustment procedure to be used when diagnosing the Brake
Light Switch (BLS) which may set a DTC C1249 (BRZ) in the ABS or VDC system memory. The
Service Manual will be revised to include this procedure in the future.
SERVICE PROCEDURE / INFORMATION
NOTE: The customer should be made aware that if their driving habits include a rapid “pumping”
of the brake pedal, this action may cause these DTCs set. This becomes more of a possibility if the
stop light switch is out of adjustment. If this driving tendency applies, these DTCs may continue to
reset until the customer’s driving habits are changed. Confirm the customer fully understands this
information before proceeding further with any diagnostics.
Another possible cause is a faulty or improperly adjusted brake light switch.
IMPORTANT: Before proceeding with the stop light switch adjustment procedure outlined
below; complete the diagnostic procedure found in the applicable Service Manual for the DTC
stored in memory.

Subaru Service Bulletins are intended for use by professional technicians ONLY. They
are written to inform those technicians of conditions that may occur in some vehicles, or
to provide information that could assist in the proper servicing of the vehicle. Properly
trained technicians have the equipment, tools, safety instructions, and know-how
to do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

1. Connect the Select Monitor (SSMIII). While monitoring the Current Data Display,
select the data for the stop light switch signal and master cylinder pressure.
2. Use the following procedure WITH THE ENGINE IDLING, to check the brake light
switch adjustment and master cylinder pressure:
1)	Confirm the stop light switch signal shows “OFF” with your foot off the brake
pedal.
2) N
 ext, pump the brake pedal 5 times and after the 5th press of the pedal, release the
pedal slowly and watch the value for Master Cylinder Pressure decrease.
3)	When the brake light switch status turns from “ON” to “OFF”, the master cylinder
pressure should be less than 1 MPa (10 bar or 145 psi).
3. If the pressure measured exceeds 1 MPa (10 bar or 145 psi) as indicated on the
SSMIII, increase the “Gap A” dimension by .5 mm. CAREFULLY rotate the brake
light switch SLOWLY, counter-clockwise approximately 1/4 turn until you feel it
begin to release from the retainer. Follow the instructions in Step 5 below to increase
“Gap A” by the required dimension.

4. Reinstall the stop light switch back into the retainer but do not lock it into place.
5. While holding the brake pedal up against the stopper and with the .5mm spacer in place, move
the switch in toward the pedal until the plunger just contacts the .5mm spacer (do not depress
the plunger). Turn it back to the right (clockwise) until you feel it snap back into the “locked”
position. You will need to develop a “feel” for the adjustment notches along with how the brake
light switch releases and locks back into place. This will involve some trial and error. Once the
stop light switch is locked back into position, remove the spacer.
6. Recheck the stop light switch operation and master cylinder pressure again following the Step 3
procedure.
