TSC 523964.05 – Y68 Solenoid Valve for Reducing Pressure (TLS), Current Too Low

TSC 523964.05 (TSC )

Code: 523964.05

Shortcode:

Description:

This diagnostic trouble code, TSC 523964.05, is triggered when the control unit measures too low a current at the signal input of the solenoid valve for reducing TLS pressure (Y68). This indicates that the circuit is either shorted to a supply lead or is open.

Reaction:

When this error occurs, the solenoid valve for reducing the TLS pressure may not operate correctly, potentially leading to impaired functionality of the TLS system.

Recommendations:

Inspect Solenoid Valve Circuit:

  • Check for Open Circuits or Shorts:
    • Examine the wiring for any signs of open circuits or shorts to a supply lead.
    • Repair any identified issues in the circuit.

Inspect Solenoid Valve:

  • Check Solenoid Valve Connections:
    • Ensure that the solenoid valve Y68 is properly connected and not damaged.
    • Replace the solenoid valve if it is faulty.

Verify Control Unit:

  • Check for Control Unit Issues:
    • Inspect the control unit for any faults that could affect the current measurement.
    • Repair or replace the control unit if necessary.

Note:

Ensuring proper current flow to the solenoid valve for reducing TLS pressure is crucial for its proper operation. Regular inspections and maintenance of the solenoid valve circuit and connections are recommended.
