REVISION SUMMARY
This bulletin was revised extensively because the TSX (L4) and TSX Sport Wagon 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.

training to correctly and safely maintain your vehicle. These procedures should not be attempted by “do-it-yourselfers,” and you should not assume
