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.). If one or more of the self-tests 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 U3000:53 (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.
