This bulletin applies to 2017 Honda Clarity Electric vehicles. The high-voltage lithium-ion battery in this vehicle has an eight-year or 100,000-mile warranty. But unlike earlier vehicles with high-voltage batteries, this model does not set a DTC when the battery pack capacity value has reached the level for battery replacement under warranty.
To check the battery pack capacity in the Clarity Electric, you must use i-HDS. Go to the Electric Powertrain Data list and look at the battery pack capacity signal. If the value reads less than 55 Ah and the battery is still under warranty, the battery is eligible for warranty replacement.
