|U3000 code tech notes

  • U3000:42 (Control Module: General Memory Failure) - This Diagnostic Trouble Code (DTC) sets if the Power Steering Control Module (PSCM) detects an internal memory data error during the data plausibility check.
  • U3000:46 (Control Module: Calibration/Parameter Memory Failure) - This DTC sets if the PSCM detects an internal calibration data error during the data plausibility check.
  • U3000:49 (Control Module: Internal Electronic Failure) - If at any time during normal operation the PSCM detects an internal hardware error, DTC U3000:49 is set.
  • U3000:4B (Control Module: Over Temperature) - This DTC sets if the PSCM detects an internal over-temperature condition. Steering assist is reduced to protect the Electric Power-Assisted Steering (EPAS) electronics. Steering assist returns to the normal operating level when the system has cooled down.
  • U3000:53 (Control Module: Deactivated) - This DTC sets if the PSCM detects an internal error which causes a permanent de-activation which is not recoverable with an ignition cycle.
  • U3000:56 (Control Module: Invalid/Incomplete Configuration) - This DTC sets if the PSCM detects a mismatch of data structure in the non-volatile memory.
  • U3000:96 (Control Module: Component Internal Failure) - This DTC sets if a fault causes the EPAS to enter a failure mode.

    |U3000 code description

    The Power Steering Control Module (PSCM) monitors various inputs and outputs of the Electric Power-Assisted Steering (EPAS) system in order to keep the system operating at peak capacity. Information provided by sensors (steering torque, vehicle speed, vehicle travel distance, etc.) are all compared to programmed and learned information. Likewise, outputs like the motor and steering rack (travel) are tested against programmed and learned information. The Diagnostic Trouble Code (DTC) will set when the PSCM detects a Control Module Failure Or Erratic.
