Check the iN VIN status for eligibility.
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.

INSPECTION PROCEDURE
NOTE: 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 high- pressure service port and the low-pressure service port.
2. Evacuate the A/C system. Measure the amount of refrigerant oil removed from the A/C system after the recovery process is completed.
NOTE:
• Make sure to put the same amount of new refrigerant oil back into the A/C system before charging.
• 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.

Page 9 of 11
18. Check the inlet and outlet joints and the receiver/dryer cap for leaks.
NOTE: Leaks from the O-rings or the receiver/dryer cap are not covered by this bulletin.
• 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.
19. 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.
