REVISION SUMMARY TSX V6 models were added. BACKGROUND American Honda is extending the warranty on the EPS (electric power steering) control unit to 15 years from the original date of purchase with unlimited miles. This warranty covers vehicles where the steering feels heavier than normal, or is hard to turn, particularly when the vehicle is not moving, and either the EPS indicator blinks with no DTCs, or the EPS indicator comes on steady with DTC 32-09 (motor current correlation), DTC 32-08 (EPS control unit internal circuit [current sensor]), or DTC 61-04 (motor harness malfunction). The warranty extension 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. CLIENT 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 diagnosis and, if directed by the results, replace the EPS control unit.
