Safety Recall: Fuel Cell Stack – Power System Problem Message is Displayed

 

AFFECTED VEHICLES

Year Model Trim VIN Range
2017 Clarity Fuel Cell ALL Check the iN VIN status for eligibility

 

BACKGROUND

The fuel cell stack generates electricity to power the vehicle through a process that combines hydrogen from the fuel tanks and the oxygen from the air. The stack is made up of many individual cells that act like batteries. Each of these cells is monitored individually by the vehicle so if there is a problem with the fuel cell, a warning message appears on the dash before the fuel cell shuts off. Because of a software issue, the monitoring system may shut down the fuel stack at the same time the message appears, resulting in an unexpected loss of motive power, which reduces vehicle control and increases the risk of a crash.

 

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.

Some vehicles affected by this campaign may be in your new or used vehicle inventory.

Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the customer or anyone else harmed as a result of such failure. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before leasing it.

 

CORRECTIVE ACTION

Update the FC (fuel cell) system with the i-HDS.

Latest ECU Software

 

Vehicle Communication Interfaces (VCI)

The i-HDS software supports the use of a generic pass-thru VCI that is compliant with SAE J2534-1 and J2534-2. However, Honda recommends the Denso DST-i or the Bosch MVCI for use on Honda and Acura vehicles, as Honda has worked closely with these manufacturers to ensure their hardware and our software interact safely and within the J2534-1 and -2 specifications, for both diagnostics and reprogramming. If you choose to use a generic VCI, please carefully consider the customer and technical support options you will receive from your chosen device supplier. Honda does not provide technical or customer support for generic VCI devices.

The VCI Application Table below lists devices that either are approved and supported by Honda or are known to have completed and passed an independent, exhaustive validation program with our i-HDS software suite.
