DESCRIPTION
Some customers may complain of a steering wheel vibration (in a rotational direction), when they are not
holding onto the steering wheel. The vibration stops when holding onto the steering wheel or when driving.
This may be caused by improper control logic of the EPS control module. To eliminate this concern, the
EPS control logic has been modified.
Customers having this concern should have their vehicle repaired using the following repair procedure.
