SUBJECT:	Revised Brake Light Switch Adjustment Procedure
for DTCs C1531 and C0054
INTRODUCTION
This bulletin provides a revised adjustment procedure to be used when diagnosing Brake Light
Switch (BLS) -related DTCs C1531 and/or C0054. If the BLS is out of adjustment, the ABS and/or
VDC warning lamp may illuminate.
SERVICE PROCEDURE / INFORMATION
IMPORTANT: Before proceeding with the BLS adjustment procedure outlined below, review the
related diagnostic procedure completely in the applicable Service Manual for the DTC stored in
memory.
1. Before removing or adjusting the BLS, put a reference mark (a) on the threaded/notched
portion as shown in the illustration below.

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.

2. As shown in the next illustrations, measure the brake pedal stroke by first measuring the
distance “A” between the floor mat and the pedal. Depress the brake pedal slowly until the
brake lights come on “B” then record the second measurement. Subtract “B” from “A” to
obtain the pedal stroke measurement.
The specification for pedal stroke to activate the BLS is 5.5mm +/- 2.5mm
(>3mm but <8mm).
•
If the measurement (switch activation) is out of specification, the BLS will need to be
adjusted. When the brake lights come on too soon (not enough pedal stroke), the BLS
needs to be adjusted “inward” toward the bulkhead while if the pedal stroke is excessive
before the brake lights come on, the BLS will need to be adjusted outward toward the
steering wheel. The BLS adjustment is sensitive and in most cases, moving it just one
notch should bring the operation into specification since one notch is equivalent to
approximately 4mm of movement.
3. If it is determined the BLS needs adjustment, rotate the switch approximately 45 degrees to
the left (counter-clockwise) to release it from the pedal bracket. You will need to develop a
“feel” for the adjustment notches along with how the BLS releases and locks back into place.
Move the BLS inward or outward as required using your reference mark (see Step 1) as a
guide then rotate the BLS to the right (clockwise) to lock it back into position. Re-measure
the pedal stroke. If the switch operation is within the specified limits, the adjustment
procedure is complete. If the switch operation is still out of range, repeat the adjustment
procedure.

mark and the Brake
Light Switch re-positioned
