Description:

This diagnostic trouble code, TSC 523847.06, is triggered when the control unit measures too high a current at the signal input of the solenoid valve for building up pressure (Y69). This indicates a short to ground in the circuit.

Reaction:

When this error occurs, the solenoid valve for building up pressure in the TLS may become overloaded, potentially leading to overheating, damage, or malfunction of the valve.

Recommendations:

Inspect Solenoid Valve Circuit:

• Check for Shorts to Ground:
  • Examine the wiring for any signs of short circuits to ground.
  • Repair any identified shorts in the circuit.

Inspect Solenoid Valve:

• Check Solenoid Valve Connections:
  • Ensure that the solenoid valve Y69 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 cause high current measurements.
  • Repair or replace the control unit if necessary.

Note:

Maintaining proper current levels to the solenoid valve for building up pressure in the TLS is crucial for its correct operation. Regular inspections and maintenance of the solenoid valve circuit and connections are recommended.
