REVISION SUMMARY
Under AFFECTED VEHICLES, 2021 Accord Hybrid was removed.
BACKGROUND
American Honda is extending the warranty on the A/C condenser to 10 years from the original date of purchase with
unlimited miles.
This warranty extension only covers vehicles that have a defective A/C condenser from the factory. The A/C condenser
was not manufactured to specification. As a result, corrosion may develop in the form of tiny holes in the condenser tube
walls that allow the refrigerant to leak out.
This does not apply to any vehicle that has a leaking condenser due to foreign object damage.
It also does not apply to any vehicle that has ever been declared a total loss or sold for salvage by a financial institution or
insurer, or has a branded or similar title under any state’s law.
CUSTOMER NOTIFICATION
Owners of affected vehicles will be sent a notification of this campaign.
Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.
CORRECTIVE ACTION
Do the inspection procedure and, only if there is a leak in the A/C condenser caused by corrosion or other manufacturing
condition, replace it.

CUSTOMER INFORMATION: The information in this bulletin is intended for use only by skilled technicians who have the proper tools, equipment,
and training to correctly and safely maintain your vehicle. These procedures should not be attempted by “do-it-yourselfers,” and you should not
assume this bulletin applies to your vehicle, or that your vehicle has the condition described. To determine whether this information applies, contact
an authorized Honda automobile dealer.

INSPECTION PROCEDURE
NOTE: Make sure you review the precautions when working with the A/C system.
1. Evacuate and recharge the A/C system with the appropriate dye for the vehicle.
NOTE:





When using the Robinair R-1234yf A/C Recover, Recycle, Recharge Machine, a system vacuum is automatically
done when it recharges the system. Use the automatic vacuum check for this bulletin.
For additional information on how to check if the condenser is leaking, go to service bulletin 07-030 A/C
Leak Detection.
If the refrigerant level is low, the compressor may not activate. Fill the system with enough refrigerant to engage
the compressor.
If there is a large leak in the system, the vacuum leak test may fail and you will be unable to add refrigerant to the
system. In that case, continue to step 3, and use the ultrasonic leak detector with the system under vacuum to
identify where the leak is. For details on how to use it, watch the Tech2Tech video, "Check for A/C Leaks with the
Ultra Sonic Leak Detector."

2. Turn on the A/C, set the climate control to MAX COOL, and make sure the ECO switch is turned to OFF.
NOTE:



Allow the dye to circulate in the A/C system for a minimum of 60 minutes before inspecting for leaks. Continue to
step 3 while the A/C system is circulating the dye.
If the customer is unable to leave the vehicle for an extended period, have the service advisor schedule a follow-up
appointment 24 to 48 hours later.

9. With the help of an assistant, pull the front bumper away from the side spacers, then release the bumper from the
hooks on the upper beam.
With fog lights only: Disconnect the connectors.
10. Disconnect and remove the horns.

11. Remove the horn brackets.

14. Check the joints between the horizontal tubes and the vertical pipes.

15. Check the inlet and outlet joints and the dryer cap for leaks.
NOTE: Leaks from the O-rings or the receiver/dryer cap are not covered by this bulletin.

Examples of leaks detected with dye
Leaks will appear fluorescent green/yellow under UV light.

Some leaks are visible with the correct angle of UV light. This leak is deep in the groove between fins.

Some leaks may not be visible from certain angles. Aim the UV light from different angles to detect leaks on horizontal
tube surfaces.

Some condensers may have multiple leaks.




If the condenser is leaking, go to the next step.
If the condenser is not leaking, this bulletin does not apply. Continue with normal troubleshooting.

16. Make sure the leak is not caused by a foreign object.
There are several types of damage that can result in a leak. This bulletin is for leaks that are caused by the
manufacturing process. Damage like those caused by foreign objects that break the tube face are not covered under
this warranty extension. A foreign object may damage the fins, but as long as the tube face is not impacted, the leak is
covered under this warranty extension.




Tube face damaged by foreign object – This bulletin does not apply, continue with normal system troubleshooting.
Foreign object damage but tube face is not damaged, or the tube face is corroded – Go to REPAIR PROCEDURE.
No damage or corrosion found but the condenser is leaking – Go to REPAIR PROCEDURE.

REPAIR PROCEDURE
NOTE:
 Only replace the A/C condenser under this warranty extension if it is leaking due to corrosion or manufacturing defect.
 Make sure you review the precautions when working with the A/C system.
1. Follow the equipment manufacturer’s instructions, and connect the A/C recover/recycle/recharge machine to the highpressure service port and the low-pressure service port.

2. Recover the refrigerant from the A/C system.
3. Measure the amount of refrigerant oil removed from the A/C system after the recovery process is completed. Make
sure to put the same amount of new refrigerant oil back into the A/C system before charging.
