Campaign - ABS Electronic Control Unit Cover
NUMBER: WVP-26DATE: June 2010
Revised 08-19-10
APPLICABILITY:
2010MY Subaru Legacy & Outback
SUBJECT:
ABS Electronic Control Unit Cover
INTRODUCTION
Subaru of America, Inc., has determined that certain 2010 Legacy and Outback models may have been produced with a plastic cover on the ABS (anti-lock brake system) electronic control unit that may have been cracked during the manufacturing process. The ABS electronic control unit is an integrated part of the brake hydraulic unit located in the engine compartment. If the cover is cracked and the electronic control unit is exposed to water, particularly from a high pressure source such as a garden hose or pressure washer, water can enter the unit and potentially cause a short circuit. If this were to happen, the unit will go into "failsafe" mode and the "S" warning light on the instrument panel will illuminate alerting the driver of a malfunction. When the warning light is on, the ABS function shuts down; however, the conventional brake system will continue to operate normally. In other words, even if the vehicle experiences this condition, the braking system will continue to function.
This Service Program will involve inspecting the ABS electronic control unit plastic cover for cracks.
^ If no cracks are found, no further action is required. Since the cracking condition was the result of the manufacturing process, the cover is not susceptible to cracking in the future.
^ If cracks are found, the ABS hydraulic unit must be replaced.
