DTC U3000: Control Module: Description

WARNING: This page is about a different car, the 2013 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.

The PSCM is self monitoring and will carry out self-tests at specific intervals (initial power up, power down, during normal operation, etc.). Each self-test requires the voltage supply to the PSCM to be between 10 and 16 volts and the vehicle speed to be below 2 km/h (1.24 mph) for the test to take place. If one or more of the self-tests should fail, then the module will set one or more DTCs.

DTC U3000:05 (Control Module: System Programming Failure) - If an internal error is detected in the PSCM hardware, DTC U3000:05 is set.
DTC U3000:41 (Control Module: General Checksum Failure) - If at any time during normal operation the module detects an internal software error with more than 10 volts supplied to the PSCM, DTC U3000:41 sets.
DTC U3000:43 (Control Module: Special Memory Failure) - If at any time during normal operation with more than 10 volts supplied to the PSCM, the PSCM fails to detect the stored DTC memory, DTC U3000:43 is set.
DTC U3000:44 (Control Module: Data Memory Failure) - If the PSCM is unable to detect the stored VIN in the PSCM during start up, DTC U3000:44 sets in the PSCM.
DTC U3000:46 (Control Module: Calibration/Parameter Memory Failure) - If at any time during normal operation with more than 10 volts supplied to the PSCM the module determines that one or more calibration files are missing/corrupt or that the incorrect EPAS column is installed on the vehicle, DTC U3000:46 is set.
DTC U3000:49 (Control Module: Internal Electronic Failure) - If at any time during normal operation with more than 10 volts supplied to the PSCM the module detects a software or internal hardware error, DTC U3000:49 is set.
DTC U3000:61 (Control Module: Signal Calculation Failure) - If the PSCM detects that assist torque calculation is faulty due to a software failure in the module, then DTC U3000:61 sets.
DTC U3000:96 (Control Module: Component Internal Failure) - This DTC sets if a fault causing the EPAS system to enter the system failure mode occurs for three consecutive ignition cycles.
