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

05/01/25

REVISED:

02/06/26

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.
Warranty Claim Submission Minimum Requirements:
1. Completed A/C Performance Check Worksheet(ALL PAGES)
2. Involvement of Techline and DSQM through normal escalation process
3. Submission of a Quality Monitoring Report (QMR) prior to repair order closure, including the
A/C performance check worksheet attached (this is a new worksheet)
WARNING: Failure to complete and provide any of the above warranty submission requirements
will result in claim rejection.
For any questions related to Warranty claims, contact the Claims team directly.
The information in this document is designed to help guide retailer staff through the
recommended diagnostic technique, appropriate fail code selection, and QMR requirements.

CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD
RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.
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.

Subaru of America, Inc. is
ISO 14001 Compliant
ISO 14001 is the international standard for
excellence in Environmental Management
Systems. Please recycle or dispose of
automotive products in a manner that is friendly
to our environment and in accordance with all
local, state and federal laws and regulations.

TOOL REQUIREMENTS:
Subaru of America requires the use of Traceline dyes to assist in diagnosing refrigerant leak concerns.
Traceline TP3840 can be sourced from many local auto parts suppliers. Traceline TP9815 and the
required tools can be purchased at www.subaruretailersolutions.com.

SERVICE PROCEDURE & CLAIM PROCES FLOWCHART:
The following basic flow diagram is meant to support retailers with the proper diagnosis and
reporting requirements for AC performance related concerns.

REFRIGERANT LEAK DETECTION PROCESS:
IMPORTANT: To ensure proper diagnosis, please refer to the SOA Techclips A/C Leak Check
Training video prior to performing the following steps. (MUST be logged into STAR-U to access)
WARNING: The Initial Setup & Performance Inspection steps 1 - 5 MUST be completed prior to any
evacuation or recharging of the AC system. If the pressures are within specification evacuation and
recharge are NOT necessary.
INITIAL SETUP & PERFORMANCE INSPECTION (PRIOR TO LEAK INSPECTION):
1. Connect AC manifold gauges and insert a thermometer in center vents.
2. Refer to the service manual procedure to inspect refrigerant pressures and performance: (Click

3. Conduct an AC performance test: The following characteristics indicate a potential refrigerant leak:
1. Pressures on both the high- and low side are low
2. Pressures on high- and low side are equal
3. High-pressure side is low
4. Low pressure side is low
4. Do not recover refrigerant immediately. If the characteristics are not one of the listed above, refer
to the service manual click path Heater & Air conditioner/Ventilation ˃ Air Conditioner ˃
Refrigerant Pressure with Manifold Gauge Set ˃ Inspection. There is no need to evacuate and
recharge for diagnosis.
5. If AC pressure characteristics are one of the four listed in Step 3, evacuate and recharge according
to the applicable service manual and proceed to the Refrigerant Leak Inspection Process below.
REFRIGERANT LEAK INSPECTION PROCESS:
STEP 1: Perform a visual inspection of the A/C components. Look for refrigerant oil stains and any
possible physical damage due to impact.

Step 3 – For vehicles requiring TP-3840 dye: Evacuate and vacuum the system for 30 minutes. For
vehicles requiring TP-3840, inject 3 grams of dye into the low-side service port, then recharge the
system according to the applicable service manual. Finally, run the vehicle with the A/C set to max.
for 30 minutes.
Step 3 – For vehicles requiring TP-9815 dye:
Evacuate and vacuum the system for 30 minutes. Recharge the system according to the applicable
service manual. With the A/C system not operating, unscrew the EZ-Ject dye handle completely and
screw the dye cartridge into it. Hold the cartridge vertically with the small cap on top. Remove the
cap and screw the cartridge firmly onto the coupler. Turn the handle to advance the plunger until
a small amount of dye exits the assembly. Remove the adapter/purge fitting—the coupler is now
purged. Connect the coupler to the low-side service port on the vehicle. Turn the plunger until 3
grams of dye are injected. Start the vehicle and run it for 30 minutes with the A/C set to max.
STEP 4: Using the UV light, check the following areas:
Under Hood
1.

Pipe-to-expansion valve connections (especially high-pressure side).

2.

Pressure sensor connection and T-fitting.

3. Welded joints along the liquid line to the condenser.
Condenser
4.

Pipe/condenser connection (bottom side).

5.

Low-pressure hose connection before the heat exchanger.

6. Welded sections and receiver/dryer.

7.

Inspect condenser face for damage (rock chips).

Compressor & Hoses
8.

High-pressure hose-to-compressor and condenser connections.

9.

Flexible rubber hoses (watch for slow leaks).

10. Service port check.
11. Check compressor (note: shaft seals may allow minor acceptable leakage).
Low-Pressure Side
12. Expansion valve outlet.
13. Compressor low-pressure line & service port.
Evaporator & Interior Components
14. Rear evaporator lines and connections.
15. Evaporator drainage test after running the blower.
16. Inspect inside vents for refrigerant traces.
STEP : Has the source of the leak been identified?
Yes: Perform the repair following the applicable Service Manual. If the vehicle is within 6
months of its production date, consider submitting a QMR to help support quality initiatives.
No: Proceed to Step 5.
STEP : Escalate to Techline:
Has the source of the leak been identified after working to identify the leak with Techline?
Yes: Perform the repair following the applicable Service Manual. If the vehicle is within 6
months of its production date, consider submitting a QMR to help support quality initiatives.
No: Techline will proceed with the normal escalation process and escalate the case for
District Service & Quality Manager (DSQM) involvement.
STEP : DSQM Technical Assistance:
Has the source of the leak been identified during DSQM technical assistance?
Yes: Perform the repair following the applicable Service Manual. If the vehicle is within 6
months of its production date, consider submitting a QMR to help support quality initiatives.
No: A Quality Monitoring Report (QMR) is required for any AC condition where the source
of the leak cannot be identified and Fail Code CHR is used prior to repair order closure. The
report MUST include the following:
