DTC U3000: Control Module: Description

The PSCM is self monitoring and performs 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 at or above a specific level (above 6 volts, above 9 volts, between 10 and 17 volts, etc.) for the test to take place. If one or more of the self-tests should fail, the module sets 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 is set.
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 is set.
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 one or more calibration files are missing or corrupt, or 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 a faulty assist torque calculation due to a software failure in the module, DTC U3000:61 is set.
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 3 consecutive ignition cycles.
