CSM 523343.04 — Single Lever Control Trigger Sensor Circuit Voltage Low

CSM 523343.04 (CSM )

Code: 523343.04



This error code, CSM 523343.04, indicates that the sensor voltage in the single lever control trigger circuit is too low. This issue can be caused by a faulty sensor, issues with the wiring, or a problem in the power supply to the sensor.


The function of the single lever control is disabled to prevent incorrect operations due to low sensor voltage.


Inspect Sensor:

  • Check the single lever control trigger sensor for any signs of malfunction. Replace the sensor if it is found to be defective.

Check Wiring and Connections:

  • Inspect the wiring and connections in the sensor circuit for any signs of damage, loose connections, or corrosion. Secure and clean all connections to ensure proper electrical contact.

Measure Circuit Voltage:

  • Use a multimeter to measure the voltage in the sensor circuit. Ensure that it is within the specified range and address any issues causing low voltage.

Evaluate Power Supply:

  • Verify that the power supply to the sensor circuit is functioning correctly. Repair or replace the power supply if it is found to be inadequate.

Reset and Test System:

  • After resolving the issue, reset the system and conduct tests to ensure the sensor voltage is within the acceptable range and that the single lever control function is restored.


Maintaining the correct sensor circuit voltage is crucial for accurate sensor performance and reliable system operation. Regular checks and maintenance of the sensor, wiring, and power supply can help prevent low voltage issues.
