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 U3000:46 (Control Module: Calibration/Parameter Memory Failure) - This DTC sets if the PSCM detects an internal calibration data error during the data plausibility check.
• DTC U3000:49 (Control Module: Internal Electronic Failure) - If at any time during normal operation the PSCM detects an internal hardware error, DTC U3000:49 is set.
• DTC U3000:4B (Control Module: Over Temperature) - This DTC sets if the PSCM detects an internal over temperature condition. Steering assist is reduced to protect the EPAS electronics. Steering assist returns to the normal operating level when the system has cooled down.
• DTC U3000:53 (Control Module: Deactivated) - This DTC sets if the PSCM detects an internal error which causes a permanent de-activation which is not recoverable with an ignition cycle.
• DTC U3000:56 (Control Module: Invalid/Incomplete Configuration) - This DTC sets if the PSCM detects a mismatch of data structure in the non-volatile memory.
• DTC U3000:96 (Control Module: Component Internal Failure) - This DTC sets if a fault causes the EPAS to enter a failure mode.
