Power Steering Control Module (PSCM)

The PSCM  manages the EPAS  system. The PSCM  receives vehicle speed information from the PCM via the HS-CAN  bus, the module also receives information from the steering shaft torque sensor to determine the amount of assist that is needed. At lower speeds, the control module will provide greater assist. At higher speeds, the control module will provide less assist. The PSCM  is part of the steering column and is not serviceable separately.

The PSCM  is self-monitoring and has the capability of setting and storing DTCs. Depending on the DTC set, the control module will enter into a "safe mode" and will provide a set amount of assist to the EPAS  system.
