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 U3000:42 (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.
