DTC U3000: Control Module: Description

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 at or above a specific level (above 6.5 volts, above 9 volts, between 10 and 17 volts, etc.) for the test to take place.

• DTC U3000:46 (Control Module: Calibration/Parameter Memory Failure) - If at any time during normal operation with more than 6.5 volts supplied to the PSCM the module determines that one or more calibration files are missing/corrupt or that the incorrect EPAS gear is installed to the vehicle, DTC U3000:46 sets.
• 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 6.5 volts supplied to the PSCM, DTC U3000:41 sets.
• DTC U3000:49 (Control Module: Internal Electronic Failure) - If at any time during normal operation with more than 6.5 volts supplied to the PSCM the module detects a software or internal hardware error, DTC U3000:49 is set.
• DTC U3000:96 (Control Module: Component Internal Failure) - This DTC sets if there is an internal failure of the PSCM or if multiple failures have occurred over a short period of time. If one or more of the self-tests fail, the module sets one or more DTCs.
