DTC U3000: Control Module: Description
WARNING: This page is about a different car, the 2012 Ford Pickup. 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 at or above a specific level (above 6.5 volts, above 9 volts, between 9 and 18 volts, etc.) for the test to take place.
- 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 U3000:46 (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 U3000:49 (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.
