2003 Subaru Outback F6-3.0LFACTORY OEM SERVICE PROCEDURE
Keyless Entry - Improved Control Module
SOURCE: Subaru Tech Tips
TITLE: Keyless Entry Control Module Interchangeability
APPLIES TO: All 2003 Models
SERVICE TIP:
Customers driving 2003MY vehicles may complain about the range of their system or that it works intermittently. This may be related to external electrical interference. This condition may be improved by replacing the older module with the newer/improved module, which was introduced in 2004. The replacement matrix is shown.
While this will improve range in most situations, everyone needs to understand that keyless entry operates on radio frequencies that are regularly affected by various outside influences. Installation of a new module may not necessarily improve range in all situations.
