U3000 Lincoln Code - Control Module Failure or Erratic

Quick Answer

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. Common causes include Faulty Control Module, Control Module harness is open or shorted, Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U3000 Lincoln 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.

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.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the U3000 Lincoln code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
