SERVICE BULLETIN
APPLICABILITY:	2008MY and Later Impreza, WRX and STI
NUMBER: 03-72-14
2009MY and Later Forester M/T Equipped Vehicles
DATE: 02/20/14
with Hill Start Assist
SUBJECT:
Hill Start Assist (HSA) Warning Light, DTC C0076
INTRODUCTION
This bulletin provides information to address a customer concern of
intermittent operation of the Hill Start Assist warning lamp. When
the HSA warning lamp is illuminated, the hill start assist system
is inoperative. DTC C0076 may be stored in memory along with
detail codes 2610H and / or 2620H. All of these codes refer to the
operation of the clutch switches.
SERVICE PROCEDURE / INFORMATION
There are 2 switches operated by the clutch pedal assembly, one sends an on-off signal to the cruise
control system (if equipped) and the other an on-off signal for the starter inhibit (clutch start switch).
•
For detail code 2610H, check the clutch pedal switch signal using the SSMIII following the
procedure in the applicable Service Manual.
•
For detail code 2620H, check the clutch pedal switch clearance following the procedure in
the applicable Service Manual.
Once it has been determined the clearance adjustments are both within specification and switch
signal functions are operating normally, the most likely cause for the intermittent HSA warning lamp
illumination is the vehicle operator resting their left foot on the clutch pedal with enough pressure to
activate the switches. Interview the customer about their driving habits then, if necessary, a road test
while observing where they rest their left foot (especially in traffic) would be a good way to confirm
the root cause of the condition. If you confirm the customer is resting their foot on the clutch pedal
when they are not: starting out, shifting, or coming to a stop, an explanation of why their driving
habits may be causing the HSA lamp to illuminate would be recommended. Because of the minimal
amount of clearance which exists when the clutch switches are properly adjusted, even the slightest
amount of unintentional pressure on the clutch pedal can result in false input signals to the respective
control units resulting in the illumination of the HSA indicator lamp.
