The steering pad switch assembly outputs the dynamic cruise control on/off signal and various control signals to the ECM.
The ECM controls the dynamic cruise control system according to the signals received from the steering pad switch assembly.
Before replacing the ECM, refer to the Service Bulletin.
The vehicle is equipped with a Supplemental Restraint System (SRS) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the precaution for Supplemental Restraint System.
