DTC U3000: Control Module: Description
WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2022 Lincoln Navigator, 2022 Lincoln Nautilus, 2022 Lincoln Corsair, 2022 Lincoln Aviator, and 2022 Ford Transit-350 HD. However, it is still accessible from the selected car via links, so may be relevant.
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 U3000:42 (Control Module: General Memory Failure) - If at any time during normal operation the module detects an internal flash or RAM memory error with more than 10 volts supplied to the PSCM, DTC U3000:42 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 U3000:4B (Control Module: Over Temperature) - If the PSCM detects the internal EPAS temperature is above the maximum allowable value for the allowable time.
- 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 U3000:66 (Control Module: Signal Has Too Many Transitions/Events) - If the PSCM detects the fault mitigation counter has exceeded a pre-set limit, DTC U3000:66 is set.
