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 U3000:42 (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.
