Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 U3000:49 (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 U3000:61 (Control Module Signal Calculation Failure) - If the PSCM detects assist torque calculation is faulty due to a software failure in the module, DTC U3000:61 is set.
