Normal Operation

The SASM broadcasts the absolute steering angle value to the PSCM over the HS-CAN at predefined intervals during every drive cycle from the first ignition ON status. During normal operation the absolute steering angle from the SASM is compared against a steering angle derived from the rear wheel speed values broadcast by the ABS module over the HS-CAN and an angle derived from the EPAS motor position. If the absolute steering angle values and the derived steering angles do not match, the EPAS system will set to a default level of assistance.

1. U1: CHECK FOR SASM DTCS 
   • Ignition ON, engine OFF.
   • Press Read Vehicle Information button to retrieve DTC s from the vehicle.
