SERVICE INFORMATION BULLETIN
APPLICABILITY:
SUBJECT:

All Models
New Procedure and Fail Code for First-Time
Undetected A/C Refrigerant Leaks

NUMBER:

10-105-25R

DATE:

05/01/25

REVISED:

06/23/25

INTRODUCTION:
This Service Information bulletin announces the new procedure and Warranty Fail Code for FirstTime air conditioning (A/C) performance concerns possibly resulting from an undetected A/C
refrigerant leak. To improve Fixed Right First-Time (FRFT) and customer satisfaction, SOA is
introducing a new procedure and fail code for first-time suspected A/C refrigerant leaks for cases
when a Technician is unable to find the source of the leak or believes there was a potential factory
under charge of the A/C system refrigerant.
To ensure proper diagnostic procedures and prevent unnecessary Warranty claims, the current fail
code AVA: A/C Refrigerant Under/Over Charge will be replaced with CHR: AC Concern,
Technician Unable to Identify Root Cause.
Please refer to the updated procedure below. For any questions related to Warranty claims, contact the
Claims team directly.
Additionally, to support quality monitoring efforts and improve data collection for A/C system
performance, submission of a Quality Monitoring Report (QMR) and the A/C performance
check worksheet (this is a new worksheet) will be required whenever fail code CHR is claimed
and when requested in certain circumstances.
The information in this document is designed to help guide retailer staff through the
recommended diagnostic technique, appropriate fail code selection, and QMR requirements.

Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

TOOL REQUIREMENTS:
Subaru of America recommends the Robinair™ LD7 Infrared Leak Detector to be used when
diagnosing refrigerant leak concerns.
•

Detection Capability:
• R134a is 0.05 ounces per year.
• R1234y is 0.01 ounces per year.

•

Proper Technique:
• Move the probe at 1-2 inches per second in a double-pass method.
• Keep probe approximately ¼ inch from the component.
• Focus on low-lying areas. Refrigerant is heavier than air.
