DTC U3000: Control Module: Description
WARNING: This page is about a different car, the 2016 Ford Special Service Police Sedan and 2016 Ford Police Interceptor Sedan. 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 U3000:42 (Control Module: General Memory Failure) - This DTC sets if the PSCM detects an internal memory data error during the data plausibility check.
- DTC U3000:49 (Control Module: Internal Electronic Failure) - If at any time during normal operation with more than 6 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 is set if there is an internal failure of the PSCM due to temperature, power supply or if multiple failures have occurred over a short period of time.
